How To Make Homemade Soap In A Crockpot

This post has been a year and a half in the making. I hope you’ll be as excited about it as I am! ;-) Ever since I started blogging and making my own homemade versions of household products I have wanted to try making soap! But I was completely intimidated by the whole process. First of all it involved math, which is not my strong suit. (OK…it’s not much math…but still). Then there were the “special ingredients” and finally, the “special equipment” needed. Well, I finally decided to tackle all my excuses for not making soap and when I did, lo and behold, it was probably one of the easier things I’ve done! That’ll teach me! (Probably not, but I can hope.)

Let me first dispel some of the silly notions I had about the soap-making process:


1.) Math. It turns out there are actually online soap calculators that do all the math for you! How cool is that?  I really should have known. You really can find anything on the www nowadays. You will need to know some simple addition, but I believe in you!


2.) “Special ingredients”.  Would you believe me if I told you I already had all but one of the ingredients I needed in my kitchen already? Well, you soapmakers will, but I’m talking to the rest of you. There were literally only 4 ingredients in the soap I made, including the water! Olive oil, coconut oil, lye and water.  Oh, and essential oil for scent if you like (but that’s optional, so it doesn’t count.)

3.) “Special equipment”.  I may have been the only person on the planet who didn’t own a stick blender before last week.  Every time I tell someone about my soap-making exploits I ask them if they have a stick blender and everyone has said…”Sure!”  So I guess it’s not that special of a special piece of equipment, but it was to me, until now. I bought an inexpensive Oster Immersion Blender at the grocery store for $24.99 and while I was there I picked up the other piece of “special equipment” I needed…a scale. Now, I used to have a scale, but for the life of me I can’t remember what became of it. This one also set me back $24.99, but I probably could have gotten away with a less expensive model. I chose THIS one because….are you ready for this???….they were buy one, get one free! :-)  You know what that means!!  One lucky reader is going to get a scale and an immersion blender to make their own soap! (More info at the end of the post.)

OK…now that I’ve dispelled some of the “myths” of soap-making….let’s get down to it, shall we?

I have to start by profusely thanking Angela at Living From Scratch for her tutorial. It was after reading through her careful, clear and complete tutorial that I finally felt like I could do this thing! So thank you Angela!


Oh, I forgot to mention, there is one more fairly important piece of equipment that is needed for this particular soap-making endeavor….a crockpot.  But I’m guessing the VAST majority of you already have one of those. If you don’t, run down to the local thrift store…I bet you’ll find one there for cheap!

First thing you have to do if you want to make soap is find a recipe. I decided to make Hot Process Soap (vs. Cold Process) because I wanted to get in touch with my roots and that’s how soap has been made for centuries! Not really…I decided on HP soap because it cures much faster than Cold Process and I’m a very impatient person. :-)  How’s that for honesty!?

You can approach this a couple of different ways. You can find a recipe online (just Google or Bing it and you’ll find a gazillion!) or you can use an online soap CALCULATOR. Basically you tell the calculator what type of oils you want to use in your soap (it lists pretty much any oil you can THINK of!) and it spits out the oil and lye measurements for you!  It’s pretty slick. It took me a little while to figure it out….but once I got it…I was convinced I will be making more soap using this thing. :-)

soap calculator

So following Angela’s lead…I decided on an 80% olive oil and 20% coconut oil mix for my soap. I also wanted to try just a small batch at first…so I put 16 ounces in the calculator for the weight of the oil I would be using…and like MAGIC it came up with my “recipe”.

  • 12.8 ounces Olive oil
  • 3.2 ounces Coconut oil
  • 6.0 ounces Water
  • 2.2 ounces Lye

Are you beginning to see why the SCALE is so important? The scale made this a CINCH.

Place your bowl on the scale (and this is where a TINY bit of math comes in…but if *I* can do it…*you* can do it!) and then add the amount of olive oil needed to the weight of the bowl. So my bowl was 35.4 ounces. I needed to add 12.8 ounces of olive oil. Adding the two numbers together I got 48.2. So all I had to do was pour in the olive oil until the scale reached that number.

Then do the same thing with the coconut oil. It was actually kind of FUN channeling my inner mad scientist. ;-)

Pour the oils into your crockpot set on Low.

After you have measured/weighed your oils, it’s time to add the water and lye. Lye was one of those “special ingredients” I talked about before….and I won’t lie….it’s not EASY to find. BUT, all I had to do was ask the nice gentleman at our local hardware store to order me some and I had it in my hot little hands two days later. It’s used as a drain cleaner, so you will want to look for it in the plumbing section. This is what my container looked like. You just need to make sure it’s labeled as 100% lye, NaOH.

make your own bar soap

Since it IS a drain cleaner…you can imagine how CAUSTIC it can be. It can burn skin on contact and is fatal if ingested, so you must handle with extreme care. I didn’t use any special protective gear, but I was extremely careful not to come in contact with it and made sure the area was well ventilated while pouring and mixing it. Once it’s added to the oil however, you don’t smell it at all.

If you are concerned about working with lye you can avoid it by purchasing melt and pour soap base at a craft store. That way all the lye-handling has been done for you. :-)

make your own bar soap

So, next step. Measure your water into a heat proof glass container and then add your lye to the water. IN THAT ORDER. Adding water to the lye will result in an unfortunate volcanic reaction. Stir until the lye is completely dissolved. This part gives off some pretty strong fumes, so be careful and make sure you got some ventilation going!

Next step…pour the water and lye mixture into the crockpot with the oils. Time to get out that stick blender I’ve been dying to use! ;-)  Mix until smooth and slightly thickened.

Put the cover on your crockpot (still set on Low) and wait 30 minutes.

make your own bar soap

After 30 minutes, it should just be starting to get thick around the edges, but runny in the middle. You can see from the pictures, the progression after that is fairly rapid. By one hour you should be to the point where you can turn off the crockpot, give the mixture a stir and add any fragrance if you so desire. *I* so desired!

make your own bar soap

So I added the first thing that came to my head…one of my favorite combinations….Lavender and Lemon.  I totally GUESSED on this step and added approximately 10 drops of each. I must have had beginner’s luck on my side because the soap turned out to have just the right amount of scent for me!  Not too much…just enough.

make your own bar soap

Now all that’s left to do is pour it into a mold (I used a ratty old plastic container I had lying around) and wait.

Mine had hardened enough overnight to unmold and cut. The soap will actually continue to harden for another week or two, so cutting it right after taking out of the mold is recommended. I easily cut mine into small bars with a large kitchen knife.

make your own bar soap

I can’t tell you how much I enjoyed this project….from beginning to end!  There’s just something about making your own SOAP that is incredibly satisfying. I keep a little bar of it on my kitchen sink at all times…a) because it feels and smells wonderful! and b) because it makes me smile!

I know this was a LENGTHY post…but I hope some of the enthusiasm I had for this came through. If you’re thinking you might want to give this whole soap-making thing a try…make sure and enter to win the digital scale and immersion blender giveaway!

  • Those of you who love making your own soap must have a lot of time on your hands. At my age, I have been retired for 18 years, and I worked until I was 67. If anyone thinks I will waste my time making soap they have another “think” coming.

  • Why would anyone want to go to all that work to make their own soap?
    I need a hypoallergic soap and I use Dove, either the cake soap or the liquid lotion Dove, for sensitive skin.

  • Excellent web site you have got here.. It’s hard to find quality writing like yours nowadays.
    I truly appreciate individuals like you! Take care!!

  • Hi! Do you know if they make any plugins to safeguard
    against hackers? I’m kinda paranoid about losing everything I’ve worked hard on. Any tips?

  • Hey there! Do you use Twitter? I’d like to follow you if that would be ok.
    I’m undoubtedly enjoying your blog and look forward to new

  • Hey Admin,

    I was searching for some homepage soap recipes today when I came across onegoodthing.

    Awesome stuff!

    Actually, I just launched a guide that teaches people how to make luxury soaps at home. I usually charge $X, but I’d be more than happy to send it over to you on the house. All I’d ask is that you’d consider mentioning it on your blog or writing a review.

    Let me know how that sounds.



  • I’m not really sure how I ended up here reading about soap making but I couldn’t stop reading it and now you’ve inspired me to make my own soap! This looks easy and fun. Thank you. By the way, you might try putting your bowl on the scale before turning it on and it will be 0.0 with the bowl so you don’t have to do any math. That’s how mine works anyway.

  • […] DIY Soap in a Crockpot: Would you believe you already have most of the ingredients needed in your kitchen to make homemade soap in a crockpot? There were literally only 4 ingredients in this DIY soap recipe including the water. Olive oil, coconut oil, lye and water, and of course, a crockpot! […]

  • I got 2 crockpots , so I’m going to make this soon so I don’t have to buy the laundry soap.
    I been scared to make this for years , but now I wont’ too. I really enjoyed you on the The Mom Conference today , U are my favorite. Now I gotta go make my laundry soap and your recipe for fabric softener crystals. I made the fabric softener liquid today. :)

  • I was wondering if you have a good Crock pot recipe for Goat Milk soap you would care to share. Please feel free to email me. Thank you so much!

  • […] How To Make Homemade Soap In A Crockpot {A Photo Tutorial} | One Good Thing by Jillee […]

    • I would . I have a extra crockpot bowl I intend to use . All I have to do is get a hand blender and lye! My sister in in law keeps the bowls and utensils ( even a extra hand blender) just for soap making. I’m going to do that too.

  • WHERE IN THE HELL ARE YOUR GLOVES!?!?! You should NEVER handle dangerious chemcials like lye without proper safety equipment. Also, when handling a strong base like lye you should have a some vinager handy in a spray bottle. That way if you do get any lye on your skin you can neuralize it with the vinager.

  • I saw that you had to add the weight of the bowl to the weight of the oil,lye… If you want to completely eliminate the math! ;) you can put the bowl on the scale, reset it back to zero (with the bowl still on so it thinks the bowl is part of it:)) then add what you are weighing! Super easy and requires no math skills whatsoever (I may or may it have done a happy face when I found this out)! Hope
    This helps you in the future!

  • Have you used this homemade soap to make your liquid hand soap? If so, did it turn out ok? I really like your liquid soap, but would like to get away from using the commercial bar soaps completely.

  • […] you to Jillee for her fabulous recipe! I am blogging about it so you can know you too can make soap and also to […]

  • I want to make heart shaped soaps for some friends in goddie bags for Valentine’s Day. Can I use food coloring for this soap. If so, when may I add it to the recipe?

  • Hi Jillee,
    I made my first HP Crockpost soap yesterday from a different recipe. I remembered you had made soap using the soap calc . net so between your post here and working the calc on the site myself, I’m trying to come up with a “recipe”. First of all I don’t see on your calc image above WHERE you see you needed 6oz of water and 2.2oz of Lye. I don’t see either of those amounts on the image above. Second when I use the calc for my recipe, keep in mind I’m just playing with it right now, I have everything selected just as the detailed instructions say, I’ve got my butters and oils and so on but when I click the calculate recipe there is NO Lye oz or water oz to be found, just that 38% water which is always there. Even when I put in your recipe, I don’t see the lye oz or water oz …

    WHERE did you find the lye and water oz on the image/site?

    Thank you!
    btw, my first HP crockpost soap smells divine, curing up now :) i forgot to spray the mold I used with PAM or at least line it with freezer paper and had to cut the mold in half to get the soap out … oh well lesson learned

  • Hello, I love the homemade laundry soap and the hand made soap. Do you know how to make laundry bar soap? It works a little better on clothes, and I would love to figure out how to make it for myself. Thanks :)

  • I absoluately love your post! Thank you for sharing and showing all the details. I have been hestating on making one even I have everything set to make it. Can’t wait to make my own!

  • this soap does not look right. did you ever use it? did you have any adverse reactions to the soap? ok in my studies (its never happened to me but ive always been told to beware) homemade soap that has some white spots in it in not to be used. the white spots in it are generally parts that did not completely go through the saponification process and may still be caustic!

  • We Love Being Outdoors, But Poison Is Not My Friend. I Find That Lye Soap Washes The Oil Off Better Than Regular Store Bought Body Washes. I Still Have A Reaction But It Is Much Less If I Make Sure To wash Off Before Bed.

  • Some scales have a “tare” function where it will 0 out the weight of the container on it so you can measure from 0, some do not, I had a cheaper scale that didn’t have a tare function, so I discovered if I put the container on the scale, turn it off, then turn it back on, then it registered 0 (with the container on it) and I was able to measure whatever I put in the container from 0, this obviously only works on digital scales. :)

  • I’m interested in why you say that it’s the “hot process” technique that has been used for centuries. Especially since for most people hot process is synonymous with “melt and pour”. The only difference in what you’re doing and cold process is that you’re keeping it heated for a certain amount of time, which technically you do in cold process as well, it’s just not the same temp as a crock pot.
    You’ll also want to let your soap cure for at least 3 weeks before using it. Most homemade soap is not mild enough to use right away.
    Also, plastic should never be used in the soap making process, even if it’s as a mold because the soap will break down and contaminate your soap.

  • I second the previous comment about “zero-ing” out the scale. My scale has an additional button marked “tare.” The tare function is used to set the scale back to zero. So first I would place my container on the scale, and then push the tare button. That sets the scale back to zero (basically ignoring the weight of the container). I add the right amount of olive oil, and again push the tare button. Once again, the scale shows zero, and I can then add the next ingredient. Hooray for no math!!

  • Just FYI, don’t allow the soap mixture to come into contact with aluminum products. My mom used to make her own lye soap and ran out of newspaper to line her cardboard boxes for the soap to cure in. She forgot about the aluminum rule and lined her boxes with aluminum foil. The soap mix bubbled and hissed and created noxious gasses.

  • […] night. I’m terrible at explaining the process of saponification so I’ll link you to One Good Thing By Jillee, which is an excellent blog that has great […]

  • I’m glad I ran into this site. I was trying to find information about toxicity making soap in a crock pot because I know there’s a lot of information about lead in them so I wonder if using a crock pot to make soap could get some toxic material into the soap. I think this is important as the objective most of us are looking for is precisely avoiding toxic ingredients. If anybody has information, please share, thanks

  • Do you “Zap Test” your soap? I’ve seen lots of Hot Process soap recipes that include the Zap Test. I don’t understand why I need to zap my tongue with soap for HP but not for CP? I actually followed this process for my first batch and it turned out fine.

  • Do you need to let this soap cure after its cut? If so for how long? Also, if I wanted to add oatmeal, or seeds would I do that when I add the EO for scent?

  • Homemade soap is not all that difficult. There are several websites with directions. One thing not mentioned in Jillee’s directions is:BE VERY CAREFUL WITH LYE (NaOH). Lye must be added to water!!! Never add water to lye!! Gloves and safety glasses should be worn, especially for novices. Stick blenders are great, but must be kept in the mixture while running, or splashing can produce burns. Get the kids and the pets out of the area and make sure there is good ventilation. Anne Watson puts out a good book. Kathy Miller has a good website. Bramble berry has some directions. You must follow directions. This is not a product to experiment with!!! Make a basic recipe, check out some reputable websites and see how the make variations.

  • Ah, hah!
    My comment says Tuesday, June 11, 2013 at 9.34pm, but on the east coast of Australia it isWednesday, June 12, at 1.40pm.
    How time flies.


  • I came across this site after typing, ‘vinegar and baking soda cleaning products’.
    It is a complete eye opener.
    All the things (and more) I have wanted to do, make or bake are in front of me. What tickles my fancy?! home made underarm deodorant, soap, heck I feel like I have been given the keys to the M&M factory. Where do I start.
    Oh well, since hanging up my work boots I have plenty of time.
    Thank you so much for your web site. From across the ocean in rainy Brisbane,


  • Hi,
    I was wondering if you can double the recipe for the crock pot soap? I am going to make it, and would like to make a bigger batch.
    Thank You so much for the awesome directions and photos.
    Thank You,

  • You don’t need math for the scale. There should be a tare button on it. Put your bowl on the scale and hit tare. It will zero it out so you are just weighing what is in the bowl

  • I wonder if you can add to your tutorial how incredibly important goggles are. If the lye gets in your eye it will precipitate the proteins in your lens and make it opaque. You do NOT want this to happen! I work around a lot of dangerous chemicals, but caustic (as we call it) is by far the one everyone is cautious of. Full gloves, full eye protection and immediately shower if it gets on your skin. Vinegar would neutralise it, but it’s exothermic so you could add a thermal burn to your chemical burn.

  • I have read a lot about making soap. Haven’t made it yet, but think there is other precautions you forgot to mention about the lye. From my understanding, you are not to use the bowl, blender or crockpot for anything other than making soap now. I may be completely wrong, but would rather error on the safe side with chemicals like lye.
    I am interested in trying this recipe with a little old crock pot that I have.

    • I still do not recommend making soap when I am able to buy it on sale, with a coupon it is so, so much easier. This is 2021, nearly 2022, and not 1821!

  • I just made my first batch of soap using Jillee’s recipe. Has anyone tried making a double or triple recipe in a single batch?

    Thank you.

  • I was so excited when I read the homemade soap recipe, I knew I already had everything I needed. As I’m typing my soap is making. I brought my computer in the kitchen, got everything out and got started. I’m so excited .. omg!!! And it already smells soooo good … thank you a million times over. And will definitely try the rest of the homemade recipes. I love this …..

  • Paulina: The lye water reacts with your oils and a chemical reaction takes place where you no longer have lye and oils. You now have soap! Properly made soap has no lye left in it whatsoever and is super-mild and awesome on the skin. No danger here. The whole thought of lye used to scare me until I actually made homemade soap myself and saw just how superior and completely natural it can be. The stuff for sale in the store isn’t soap but chemical laden “beauty bars”, not soap.

  • I love how easy it is to make hot process soap in the crockpot instead of doing cold process. You have instant results too and you don’t have to let your soaps cure 4-6 weeks. Instant gratification. You can totally mix this up with adding oats, ground almonds, poppy seeds, mix up your essential or fragrance oils and color with pigments and oxides. The sky’s the limit! If you want some inspiration, check out these olive oil hot process soaps at Ginger Grey Soaps. You can get really fancy!: http://www.gingergreysoaps.com/category/olive-oil-soap

  • I have a question, if the lye is poison and can cause severe burns, how come its safe to use the soap with it? I would think its not that healthy for the skin?


  • I have read many recipes using crock pots on various web sites. Some say need a dedicated crock pot for soap making and others say to just clean it with vinegar, soap and water. Since, I have never done this, but am excited to try this method, I am wondering which is correct. Do I need a dedicated crock pot or not?

  • I don’t know when or if you’re going to see this comment, but I am trying to figure out that dang soap calculator and can’t!! What are all the percentages and stuff I need to put in? I have Palm oil and shea butter, that I wanted to use too, but I just don’t get it!! I am really blonde and need things spelled out!!

  • I tried making this crock pot soap, and my soap turned out way too soft. I did some research and I think what I did wrong was I didn’t use the stick blender long enough to reach “trace.” I think a little more emphasis on trace would be a good idea in this tutorial. I do plan on trying again and I’m sure now that I figured it out I’ll have success. Thanks for this idea, would never have thought of doing this and I’ve been wanting to make soap for a long time. God bless!

  • I love making my own candles, and have plenty of scent, can’t wait to try this. I just found your site from a friend… WooHooooo!! This is gonna be fun. I have already tried the laundry soap!!

  • […] first batch of soap, I used this recipe from the blog One Good Thing From Jillee.  I had my youngest son help me and had him mix the lye […]

  • I have a question, i have grapeseed oil would that be a good subsitute for olive oil? I have EVOO as well but plan on using grapeseed oil for my body butter recipe. Also does this soap need to cure for 4wks? I have looked at other recipes using lye for soap that you have to cure the soap for about 4wks to have the lye turn the oils into soap i cant spell the actual word for it at this moment lol. I have raw shea&cocoa butter coming in next week I figure they would be a great addition to any soap making i may do as they are super good for the skin as well. thanks for any feedback.

  • I wouldn’t use anything that has touched household lye to ever touch food. No matter how well you wash it, it will never be truly clean. Would you drink out of a cup that once had motor oil in it?

    To those who do use lye – it is very CAUSTIC. It can cause serious BURNS and BLINDNESS and you should wear protective clothing (at least gloves and goggles). Also lye MELTS PLASTIC once MIXED with WATER. Make sure your stick blend has all metal blades. Use a wooden spoon when mixing the soap after the lye/water mixture has been added. Lye in powder form is stored very safely in plastic.

    With all that said, the soap that I made turned out fantastic. After a trip to the local thrift store to pick up all the “hardware” I now have dedicated soap making tools and a fantastic recipe. I have made several batches and started giving them out as gifts.

    THANK YOU!!!

  • Is it safe to use the crockpot for normal use after making the soap ? Or should i be only for the soap. I know i have looked at other recipes and they all say not to use the utinsil, cooking pots or containers for anything other than soap making.

  • I have a question: It may be a totally stupid question, BUT: Why do you use Lye in soap if it is very caustic and can burn? Is there a way to make soap WITHOUT Lye?

    Thank you! :-)

  • Hi, sorry if I missed this somewhere, but I have a question on making this soap; how does it suds up? I can tell from the coconut oil and olive oil that it will be nice and soothing and creamy, but how does it actually clean and wash, does that come from the lye?? Thanks for the tutorial, I am going to have to give it a try. Can’t wait to hear more about the book! =)

  • I tried the crockpot soap. I don’t have a stick blender, so stirred and stirred. My soap didn’t boil properly. And we had 2 power failures while it was cooking. Eventually I stirred it up and poured into a mould. But its all flakey and “bitty”, although it works well as soap. Any suggestions – apart from buying a stick blender:)

  • I love this! I just have a concern though…after using lye on the stick blender, crock pot, kitchen knife, and bowls, are these items still safe to use with food after cleaning them? Thank you for a wonderful post.

  • question: why is lye used in a soap one would use on their body if it should not be touched alone? This is not the only recipe I have found for soap and am concerned about the use of lye. Why is it not harmful in the end product?

    any thoughts or comments appreciated.

  • Hi Jill,

    First of all I want to thank you for all you share, I am definitely gonna be trying a lot of these recipes… :) Okay, my question here is about your home made bar soap… Since “LYE” is a drain cleaner and CAUSTIC and can BURN skin on contact, is fatal if ingested, has to be well ventilated when pouring and mixing it. My question is, how can this be good for your skin as an ingredient for a body soap, especially if a person has very sensitive skin? Our if someone uses this on a baby’s skin? Just wondering and concerned before I attempted this recipe for my family or to share with friends… :)


  • I adore your blog Jillee. I think you are hilarious, and brainy. I will look you up on FB soon, and perhaps I will even follow you on twitter. Be BLESSED.

  • I make my own laundry detergent and fabric softener and am totally psyched to try some of the other homemade solutions you have in your blog. I can’t wait to get started!

  • Hi there…love the website, however being an experienced soapmaker I wanted to offer a strong word of caution to you and those who will read this page on soapmaking. PLEASE WEAR PROTECTIVE GEAR!! I’m obviously not talking about a hazmat suit, but seriously, plastic goggles and plastic gloves are a must when handling sodium hydroxide (lye). Lye is a caustic chemical which can blind you and also can leave chemical burns on the skin. Splatters from the stick blender with raw soap can and will happen (ask me how I know!). I love making handmade soap, but caution and care should be used when handling a toxic, caustic chemical such as sodium hydroxide. Just my 2 cents!

  • I will be making this soap soon!!! I wonder if you can put it in little silicone mold to make it into different shapes. It would be super cute for teacher gifts too. Thanks for all your great recipes & ideas!!

    • I was wondering the same thing. If it’s not too thick, I want to put it in heart molds for Valentine’s Day gifts. Guess I’ll find out this weekend!

  • I MADE SOAP!!!! TWICE!! I’m SO excited!!! I have always wanted to make soap! I was like you, a little scared. I thought it was a huge process and a bunch of ingredients I didn’t have…I had it all, except the lye, but it was easy to get!! SO I was wondering if I could make body wash out of the soap instead of turning it into bars. I’m a huge fan of making the body wash from your recipe, so I figured I could just add more water to the soap instead of pouring it into a mold. I know the water ratio was for Dove brand soap, but I thought I’d give it a go. It might be a 1/2-1 cup too much water, but I noticed the longer it sits, the thicker it gets, so in a week or so it might just be perfect! So, yes, you can make liquid body wash from the homemade soap recipe!! Then I made bars of soap, adding ground oatmeal and sugar to make it a little like a scrub bar. Thanks so much!!! It’s been fun following you!

  • I really don’t like the contest announcement threads. Hard to get a related comment in and get a discussion going.

    Homemade soap to use in the homemade laundry soap.

    Does anyone know of a blend which will make a soap that can be used this way?

    Some people mentioned using Castile Soap instead of Fels. How do the results compare?

    Castile soap is just olive oil and lye. Super easy to make yourself. But does it work in the diy laundry soap?

    • I have heard of several people using castile soap in their laundry detergent. I have never used it before so I cannot say how it would work in a laundry detergent. My guess is that if it is good at getting grease and grime off your hands it should do well.

  • I’m not sure if its the same on yours as it is on mine but with my scale, i set my container on the scale and then turn it on. it gives me a zero reading at that point. Not necessary to weigh the bowl then figure out the total with what you add. hope it works for you too!

  • My grandmother and aunts use to make this when I was a little girl (that was a little while ago ) LOL
    I remember how clean it wouls get my clothes after playning in the dirt all day long. I use to think that it was the water they used (kid logic I guess) but I am going to make this as soon as i get a chance. It is so funny how some these same reciepes where not passed down to me. (I guess that they thought I was just a kid from the city) But I now have one so I can try it. Thanks so much :)

  • Hi Jillee!!!
    I have been reading and following your blog for a couple of weeks now and everything is amazing!!!

    My Daughter has severe eczema. that seems to flare the worst in the winter… now i love the idea of the homemade soap but i worry it will trigger a reaction. right now i am only able to use neutrogena rain bath on her, would you be able to help with any suggestions that may help make her more comfortable in the winter ? thanks!

    • Hi there, random passer-by here :)

      I find that with my eczema, I have the best reactions to soaps with no weird things in them. I had the worst luck with face soaps–for example–until I tried Coal Face from Lush. It’s a little awkward to have acne and eczema outbreaks… I tried Clean and Clear, Neutrogena (which worked, if I rotated it out with something else), but nothing worked quite the same way as the Lush products.

      I personally worry most for my own sake about many of the shelved products, b/c I’m not sure which of the many ingredients, fragrances or dyes are going to trigger a response. With the homemade stuff, I could at least go, “looks like that fragrance is bad for me, because that’s the only thing contained in here”. You know?

      That’s just my own experience, though; I’m not a doctor or anything :) What works for me might be awful for someone else. But hopefully it helps to hear someone’s experiences :)

    • My daughter’s skin is so bad this year we haven’t been able to use anything but very expensive CeraVe. I am very worried about reactions, but I really want to save money. The homemade soap recipe looks a lot more pure, but will the lye be too strong? any ideas?

  • I have made home made liquid soap from hotel soaps, and homemade laundry soap. I love that one it is easy and no smell on my clothes.. this one looks like fun.

  • I love canning my own crock pot apple butter. So delicious and in big enough batches I can give some away to friends and family. I think it will be interesting to try making soap.

  • My mobile app is giving me fits trying to scroll through all the comments and then comments. so I’m just going to have to finish all my comments in this last 1. :-) I signed up for Pinterest, and also tried to register for your forum, but sadly it would not let me. it kept giving me an error saying the referral didn’t work.. but just so you know, I found you from Lifehacker.. and I’m so glad I did! looking forward to following you. Have a great day.

  • I haven’t made anything yet, but I’m excited to find your website. I found you off of Lifehacker, and I’m really excited to try this. Lots of comments here, but I only comment to let you know that I’m excited to try this soap and thank you for posting it.

  • If your scale has a tare button all you have to do is place tour bowl on top before you turn it on or hit the tare button after it will automatically take you to zero, then you can measure out your olive oil then hit tare again and it will go back to zero again keep doing this ion each addition, voila,,no math..

  • I love making my own laundry detergent and the citrus peel enzyme cleaner, that stuff is amazing! Ive been giving it away to family and they love it too. Id love to make my own soap!

  • I have been making my own laundry soap for a while now and love it…. and I was just thinking yesterday I might try the citrus ensyme cleaner from your site!

  • I enjoy reading and learning about all the homemade DIY cleaning products that you make for around the house. I can’t wait to try some of them out. Including this soap in a crockpot, SO easy. (I am also a fan on FB).

  • I followed your recipe for homemade laundry detergent and am using it for the first time today, seems to be doing great!
    I will be making my own beeswax candles hopefully within the next week.

  • Hi I make the old fashion kind of bar soap. I made different soaps for different skin problems. and would love to try your crockpot recipe. I never had a scale but am sure going to get one. Also used beef fat and olive oil in the soaps as beef fat makes a harder soap..I have a bar here over 5 yrs and still going. I render the fat which I get free from butchers.. One thing I have read many times here..people are worried about the lye in the soap. well once my bars are out of the molds I stack them in a cool dark place for 3 wks..the lye is gone and the soap is cured and safe to use.Stacking them so air can circulate well. I have used cinnamon to give colour. aslo melted crayons for that too. Oatmeal makes a good scrub. sand also is a good scrub..sounds not nice but works well. Once you try homemade soap on your skin/face. you wont go back to store bought stuff. I am allergic to many things . Also I grate these bars to make laundry soap.. Diapers come out white and clean smelling. Now I am so keen to make more natural cleaners etc. I cant wait to see what you have on your page. I just signed up weeks ago..give or take. and I will be a faithful follower from now on. Oh.. and now I am going to try your washing soap. I use vinegaer for many things.. a rinse for hair. ..have an orange vinegar cleaner on the go. Smell so orangy and no vinegar smell. Lemons are great too.. wipe your counters down with lemons after squeezin for my liver cleaner.. hot water. linden tea or chamomile with a little honey. tstes good too.. Thanks again am glad I signed up for your letter..Much appreciated.. Have a great day

  • Soap is most definitely on the top of my list to make next. I like to make my own shea butter blends for my hair and skin (body butter)! I kinda eyeball it, but the bulk is shea butter. I melt the shea butter down in a microwave safe bowl (or on the stove) add in olive, avocado, almond, grapeseed and/or coconut oils as well as essential oils like lavender, peppermint, tea tree, or another. Let it cool and put it into your desired storage container and let it harden. It will get harder over time, but pretty soft to the touch. I love it for my skin and hair :)

  • There’s so many things I want to try to make. Soap (bars) is at the top of my list though. I love the idea of adding herbs & essential oils for differing scents! Thanks for sharing!

  • Oh my goodness. You have no idea how happy this post makes me. My Grandma and Great Grandma used to stand for hours over a big pot (witches kettle) in the back yard making. Lye soap. I have wanted some so badly. But didn’t have the pot nor want to stand over it all that time. And it is quite pricey to buy it. I certainly will be making my own now

  • I love making my own deodorant- I swear out family tried every natural product on the market and either they didn’t work or they caused allergic reactions (or both!). Finally, I looked online found a four ingredient recipe (all of which I already had) and mixed up a batch in about two minutes. That was over a year ago and we’re still using the same recipe since it works SO well!

  • I want to make skin care products (lotion & lip balm) getting the ingredients together. Am looking forward to trying to make homemade soap. Have made my own laundry soap in the past, loved it! It was the liquid-y/gelatinous kind. Kinda messy but very frugal!

  • we have been making our own laundry soap and dish soap for about 5 years now and have never regretted the switch and although its not “making” something, I use vinegar or vinegar/water for many cleaning tasks. Also recently tried dog/cat/animal repellent and am assessing if it works or not. we make homemade canned dog food when ever we butcher. Things I would like to make: homemade deoderant!!!

  • I currently make laundry detergent and am going to check out your tutorial for fabric softener crystals next! I love the soap recipe! I’ve been thinking about trying it for awhile now, I guess it’s time :)

  • I am hooked on DIY! SO to pick just one DIY product is not that easy. I would like to try the crockpot soap, but what I really would like to know how to do is how to make something that is gentle and safe to use to make my dog smell fresh. It has to be something that is easy to use as my dog care to be groomed! I just want to thank you for introducing me to all the wonderful DIY products!

  • I have been making handmade bath and body products for many years. I am however one of those Jill of All Trades Master at None, lol. I love making homemade soap but it can get really expensive and it just so happens my scale and my stick blender are broke. I would love to win and make some homemade soap again! I am a registered member of One Good Thing By Jillee Forum! Thanks for the giveaway!

  • I love making my own lotions, body butters, and shower oils using my beloved coconut oil and cocoa butter. I would also love to make soap one of these days!

  • Like you I have wanted to make soap so a very long time,,But I thought I would need special items,and trying to figure out all the measurements would drive me crazy.I am So doing this,thanks to your easy instructions.Thanks!

  • love to make: homemade laundry soap (gotta try the homemade washing soda now too!); homemade shampoo & conditioner; homemade deodorant; homemade toothpaste; homemade teas; unique homemade jewelry; and anything i can re-use or recycle into something new : )

  • I make my own powdered laundry detergent!! I love it and it is lasting forever!! I want to make more homemade items and really enjoy this site!! What has been really neat is that my great aunt made homemade detergent when she was a kiddo (think Depression Era) and it has given us new things to talk about and to share! Thank you so much for sharing with us Jillee!

  • I have only made homemade laundry soap, but am looking forward to learn how to make other homemade items! So thank you for the site and looking to learn a lot from you! Thanks

  • My fiance recently picked up the craft of soap making and LOVES it. Due to hard times, he hasn’t been able to make his own for a while. He loves finding new oils and exfoliants, colors and scents!

  • I just found this web site about a month ago. It has became my favorite site and favorite email I receive everyday. I have learned so many things on how to make my own things, all I can say is THANK YOU JILLEE. I really have enjoyed so many of your post. I have to say that my favorite DIY is making liquid bath soap from bar soap. Thank you for your time in putting this information out for all of us to learn.

  • I have used the whitening recipe and the stain remover recipe. Have saved bunches of recipes on Pintrest thinking I would make homemade soap. I’ve been extremely interested in making the shampoo bar. Love your blog, it is very educational.

  • Hi, I have made homemade laundry soap, and tried your electronic screen cleaner(love), your soft scrub(love) and I can’t wait to give this soap making a try. Thank you for writing an informative and entertaining blog!

  • […] DIY Home Thursday, January 24, 2013 How To Make Homemade Soap In A Crockpot {A Photo Tutorial} […]

  • I was browsing looking for DIY cleaners and found your blog. Love the idea of making my own soap and will have to try it. So far, I’ve only made laundry detergent but am looking to expand more as I dwindle out those old store-bought cleaners.

    I’ll look for you on facebook too. I look forward to reading more of your posts!

  • two things about making cold process soap in your crock pot. One you shouldn’t use the same crock pot for food and soap. Two the Lye will erode the shiny glaze off of the ceramics eventually.

  • First I just want to say I love all your ideas. I make a lot of my own cleaning supplies, all purpose cleaner, bathroom cleaner, dishwasher det., laundry det. I have been wanting to make soap but am also intimidated by lye, but I think after seeing you do it I feel I can too!
    Thanks for all the great info!

  • My soap making friend passed away several weeks ago. I could never get her to share her recipie with me and I fear its lost forever. Her soap would wear down thin enough to see light thru it. Your excellent post has renewed my urge to make soap and I am thinking this is a little angelic message from my very much missed friend. Thanks a bunch, gonna give it a try.


  • I have enjoyed making laundry & cleaning supplies, an am branching out into cosmetic, once I saw the ingedients of a face powder & could not pronounce some of them. Thank you for your advice.

  • I’m working on making my laundry detergent and all household cleaners. You’ve been such an inspiration. I’d love to make my own magic erasers. I LOVE the product but can’t stand buying it…and what’s in it anyway? :)

    …liked you on FB
    …registered on your forum
    …don’t do Twitter or Instagram :(

  • I love to make your homemade”shout”, a year’s worth of laundry detergents and I am in the process of making the homemade “clorox” wipes. Plus your mom’s English muffin bread is our main bread around here. I am going to start following you on facebook so I don’t miss anything else, like the soap. I don’t have one of those blenders either.

  • I have always wanted to make homemade soap! I just made the Body Butter recipe you shared on your blog and my whole family LOVES it! Thank you for your posts!

  • I definitely will be buying some lye so I can try this recipe and also glycerin so I can try making the foaming hand soap. My daughter (and me too!) love handmade soaps. I’m sure she will enjoy either helping me make this recipe or just making it herself. One particular recipe that I’ve tried is a liquid laundry detergent but I am planning on making the powdered version next time.

  • Just read article on making soap in the crock pot. What a novel idea, I remember making soap w/ my grandmother and what great memories. I really would like to try this method.
    I already make my own laundry product following the recipes on this site and there wonderful.
    Thank you for all the knowledge, and thanks for the give away for the tools to make this attempt possible.

  • I love this recipe. I’m looking forward to making the soap. I think I will add little toys to the soap. I’ve learned it can be a huge motivator for the kiddos to use the soap

  • I make our laundry soap, dishwasher soap,lemon cleaner,shampoo, toothpaste, pet shampoo, but have never tried making bar soap. Really excited that it looks easy and fun.
    I have extreme allergies to chemicals and perfume so making unscented cleaners with natural ingredients was necessary but has turned into lots of fun!!
    Thanks for another great idea.

  • I have always wanted to make my own soap, it looks like such fun! esp when i go to the specialty soap stores on vacation, and see all of their “flavors”!
    I have just not wanted to have to store designated bowls, pots, etc that can’t be used again for food! I only have so much storage space. This looks like the perfect idea, I wish I had kept my old crockpot, that I just got rid of last month, but once again, storage space!!

  • I just made my first batch of homemade dry laundry detergent. Can’t wait for the first load to come out of the dryer! We also make homemade fabric softener. Love the site!

  • Hi Jillie,
    You’re starting a soap revolution here! ;-)

    I’d like to share 2 great finds, both of which I’m totally kicked about!
    1. Window cleaning
    This I believe is a tip from a professional. I haven’t come across this on your website.
    Need- bucket, water, dawn dish washing soap, a big sponge, clean towels/rags, and a good quality squeegee.
    – Add a little bit of dawn soap to water(cold water is fine), just enough to get some suds
    – Soap the glass surface with the sponge
    – Squeegee the soap off the glass,wiping it on the towel as you go along. Be careful to only place a completely dry squeegee back on the glass.
    The squeegee actually takes the soap film off the glass–so there is no need to clean the soap off with water. Trust me, try it!
    A few extra tips: Soap the glass in sections and squeegee off, the soap solution dries pretty fast and you want to work quickly; Don’t work on glass with the sun hitting it, again the soap solution dries faster; Make sure you have a good quality squeegee that doesn’t squeak; For windows not accessible from. outside, search for videos on youtube on how to remove a window pane. It is pretty easy to do.
    It requires a little practice to perfect this technique AND get fast and efficient, so don’t despair if your first window took too long. The next one will be faster!
    I’ve cleaned my entire house with this, and some windows were not cleaned for 5 years! Clean windows without using chemicals or spending a ton are _very_ gratifying! I’ve also called window cleaning companies to find out if there is anything one can put on the windows so rain drops don’t show next time around. There is nothing!! The only trick is clean windows leave less spots than dirty windows when it rains!

    2. Low flush toilets out of regular toilets!!
    This tip is from the book A guide to natural housekeeping by Christina Strutt. Put some (clean) rocks/bricks in your toilet tank! It displaces enough water to save on the amount of water required to flush! Yay! One could also fill a plastic bottle with water instead of rocks.

    One step at a time to getting more green!


  • Jill ~

    I LOVE your blog! I’ve wanted to make my own soap for your years, but (like you) thought it would be WAY too much trouble. You’ve convinced me, here, to try it!

    Scents I’d love to try ?
    * your lavendar & lemon version
    * pepermint for christmas
    * maybe some frutiy scents for spring & summer
    + orange & coconut
    + mango
    + peach pie
    …ummmmm now I’m making myself hungry, too!
    I hope the essential oils aren’t too costly, as I don’t have ANY currently!

    Thanks!!!! ~ mt

  • I love to make my own chapstick and lotion! This recipe is great because I have been very interested in making my own soaps. I would love to learn how to make candles since I use those a lot :P

  • I would like to know how to make dishwasher cleaner and also cleaner for the new high efficiency washing machines. That seems to be the newest thing out but seems expensive!

  • I’m always buying homemade products to give as gifts; most recently it was homemade soaps. You have inspired me to make my own and to try your other cleaning recipes also. Thank you!

  • I have wanted to make soap for year! I have made some from the melt and pour chunks, but it just doesn’t seem as satisfying. I’m one of those who wants to make her own rugs, her own yarn, etc…BUT, mostly, I buy books about how to do it and never get around to actually doing it lol. If only the rest of life would slow down enough to let me become the pioneer woman I long to be.

  • I make laundry and dishwasher detergent plus shampoo, bodywash and toothpaste.
    Have you ever tried putting bar soap in your blender to make “grated” soap? works really fast and much easier!
    Also to turn bar soap into liquid hust grate, pour water over and let it sit overnight. If it isn’t liquidy enough just repeat until you are happy with the consistancy. :)

  • Still loving your site, I am the only other person without a stick blender!!!! Love making the laundry soap for everyone in my family. Now I will try this soap, can’t wait!!!

  • I would love love LOVE to make my own solid shampoo and conditioner cakes, I buy them from Lush now but they’re so expensive in Sweden and they only have so many scents to choose from… imagine being able to make it smell however you want! :D

  • I read all of your blogs, sometimes a day or two late but I really enjoy them. Just about 3 weeks ago I bought a gallon of vinegar & it’s almost empty. Vinegar & Baking Soda are now my favorite cleaning agents.. I also follow you on FB, Pinierest & your Forum.

  • I love your site and it inspires me!!! i love makeing anything homemade to save money! I am a stay at home mom and I love to find ways to help with our money at home! I love making homemade detergents and would love to know how to make the shampoo and since I got on here now I am going to try it out and see how I like it! this really is the most waesome site ever!
    thank you

  • Thanks for this post! I remember making soap with my mom when I was very little (using a kit) and I’ve always wanted to do so again.
    I also have the desire to make my own candles – nothing nicer than a dark room full of soft candle light!

  • Oh dear. You have so many responses/entries! Well, here goes…

    I LOVE making my own laundry detergent! I have been inspired by your many DIY tutorials and now use homemade dishwasher soap, dryer sheets, shower cleaner, and laundry detergent. I am so happy with my laundry detergent and the money I’m saving that I now MAKE AND SELL IT TO OTHERS! Ok, my profit so far is only about $30 after a month, but it’s a start right :)
    I’d love to make this soap. And I’d love these free products. Thanks Jillie :)

  • I love making all ofmy own cleaners now…laundry soap,dishwasher soap, even furniture polish. Now….this soap looks so easy that I think I’ll start making what we use to clean ourselves, too!

  • I haven’t really started making things yet. I’m trying to use up some of the detergents, etc I have. I did start using white vinegar as a fabric softener. I had quit using any softener about ten years ago after noticing that it always left a film on my clothes. I really haven’t noticed any difference in my clothes since using vinegar though.

  • I’ve been dying to make my own soap, but it looked too complicated! I guess I know what I am doing soon! I already make my own laundry soap, fire starters, jewelry, candles, and whatever other my craft of the moment is!

  • I love to make my own furniture. I’ve made a couple bookshelves and our headboard for out bed. When we move out of our apartment and into a bigger place, I’ll have more space to make more. Soap sound like something we’d have fun making… I hope I win.

  • I’ve also just joined the forum. Lovely place you have here.

    I’m so glad my husband sent me the link to this tutorial as featured on LifeHacker!

  • I enjoy making crocheted hats, scarves, slippers, blankets, etc. handwoven purses, candles, intricate paper snowflakes, literary quotation bookmarks, salt and sugar scrubs, wooden/glass/metal items that I hand etch or embellish with a wood-burner, scrapbooking items, hand-carved eggshells… I love learning how to make new things. I’ve been going on a journey of discovery lately and broadening my creative horizons. Your lovely soap tutorial is going to help tremendously. Thank you!
