Hydrogen Peroxide Magic 2.0


A few years ago I started compiling a list of ways to use one of my favorite cleaning ingredients, and eventually published that list as a blog post. That post was titled “Hydrogen Peroxide Magic!”, which is fitting because this stuff has so many uses that it does feel like a magic potion! Apparently a lot of you agreed with me, because that post is one of our ALL-TIME most popular!

But I knew when I posted that list that it wasn’t complete… not by a long shot! So it seemed like high time for us to revisit hydrogen peroxide, and discover a few more uses for one of the most useful items you can have in your house.

But before we begin, I thought it might be helpful to mention that we generally recommend using a 3% solution of hydrogen peroxide. This is probably the most commonly available type (it will say 3% right on the bottle), and it’s the safest to use. All of these tips were written with 3% hydrogen peroxide in mind, even if it isn’t explicitly mentioned. But enough about that!

Canker Sores

Use hydrogen peroxide to help heal painful canker sores. Swish a tablespoon or so of hydrogen peroxide around your mouth for about 10 minutes, to help disinfect the area and reduce inflammation.

Cleaning Glass

Screw a spray bottle top right onto your bottle of hydrogen peroxide, and use it like you would a bottle of Windex to clean glass and mirrors. It’s surprisingly effective, and streak-free!

Stain Remover

Treat stains from organic matter like blood, sweat, coffee, and wine. Spray hydrogen peroxide onto the stain and rub it in to help release the stain. This works best with fresh, wet stains, and may bleach some dark fabrics. Test in an inconspicuous spot beforehand to make sure.

Bathroom Cleaner

Hydrogen peroxide makes an effective and affordable mold and mildew cleaner! Spray down the surfaces in your bathroom that are affected by mold or mildew, and allow it to sit for several minutes. The gunk should be easy to remove, and the hydrogen peroxide leaves it disinfected as well!

Sinus Infections

Relieve the painful congestion of a sinus infection with the help of a little hydrogen peroxide. Mix 4 parts filtered or distilled water with 1 part 3% hydrogen peroxide, and pour it into a neti pot or a nasal sprayer. Hydrogen peroxide helps relieve congestion and reduce infection and inflammation, without creating a dependence like other nasal sprays can.

Whiten Fingernails

If you paint your nails a lot, you’ve probably already noticed that your nails can yellow over time. Get rid of the yellow tinge by applying a cotton ball soaked in hydrogen peroxide to each affected nail. Let them sit for a few minutes until the stains disappear. Make sure to apply a lotion or cuticle cream afterwards, since hydrogen peroxide can be rough on skin.

Pet Poison Control

We love our pets, but it often seems as though they are determined to eat things that are bad for them! If your dog has ingested a lot of chocolate, or any other food or substance that could be toxic, it may be necessary to induce vomiting, and you can do that with hydrogen peroxide. Measure out 1 milliliter (mL) of 3% hydrogen peroxide per pound of your animal’s weight, up to 45mL. Use a turkey baster to feed the peroxide to your pet.

This method works for dogs as well as cats, pigs, and even ferrets. However, it is NOT recommended for use on rodents, horses, rabbits, or birds.

Hydrogen Peroxide Magic 2.0

Clean Contact Lenses

Hydrogen peroxide-based cleaning solutions for contact lenses, such as Clear Care, are actually more effective a cleaning your contact lenses than traditional multi-purpose solutions. Hydrogen peroxide effectively dissolves lipids and proteins, leaving your contact lenses super clean!

However, the reason these products come with special cases or tablets to add is that the hydrogen peroxide needs to be neutralized through a chemical reaction before you can wear the contacts again. Otherwise you’ll be in for some very unpleasant eye sensations! So make sure to follow all of the directions that come with your hydrogen peroxide-based contact cleaner!

Cooler Cleaner

Pop a spray top on your bottle of hydrogen peroxide, and use it to clean and disinfect the inside of your coolers and ice chests.

Shopping Bag Saver

You can also use your spray bottle of hydrogen peroxide to clean your reusable shopping bags! You’ll feel a lot better bringing home fresh produce in a disinfected bag. Collect all your nonporous reusable bags (usually the ones made of recycled plastics), spray them down, and wipe them clean. Reusable bags that are more fabric-y can be thrown right into your washing machine.

  • A few years ago I had a tooth infection but couldn’t get to the doctor/dentist right away. It was bad enough that the pain was keeping me awake at night. I used 50/50 HP and water and rinsed my mouth 5 times a day. The infection went away.

  • H202 is fabulous to use in your washing machine, when washing colors or whites. It comes in a half gallon bottle and sold in most supermarkets. I buy a brand called “Seventh Edition.”

  • Don’t mean to go off course here, but on colors that you might worry about bleaching problems from HP, you can use rubbing alcohol instead. My ex is a firefighter and they sometimes use that for removing blood. Just a suggestion…God bless… :-)

  • Hydrogen peroxide was very helpful for me when I had braces for 2 years. I had constant canker sores. I found that using a cotton swab (q-tip) dipped in hydrogen peroxide more effective than swishing it in my mouth. I would roll the swab against a canker sore and re-swab it to make sure it was on there well. (Use different swabs for different sores in your mouth.) I found that my canker sores healed a lot faster with this method.
    Thanks for the post for other uses.

  • This is a very informative website – thank you very much!! I can just add that I use 10% undiluted peroxide for any wounds that doesn’t want to heal quick enough. It bubbles and cleans the area beautifully, and within seconds healing starts :)

    Kind regards

  • when I get a sore throat I put a few drops of H.P. in my ear and let it sizzle and pop a few minutes (head tilted) put a tissue or cotton pad up to ear and drain. Do that a few times a day and it starts to feel better.

  • To lessen the effects of bleaching fabrics and at the same time maximizing the stain removing effects of hydrogen peroxide try adding a few squirts of dishwashing detergent to the hydrogen peroxide.
    Unbelievable for pet stains on carpet’s or chairs !!!

  • I put peroxide in with my husband’s work clothes to soak. He is a heavy equipment operator. He also bleeds from aspirin He takes, I use peroxide on his stains he is amazed that I get the stains out of his white t-shirts. I wish peroxide came in gallon jugs.

  • Love your website! I have well water and I am looking for a cleaner to get rid of the orange look on my tub and tub surround. I washed my plastic shower curtain with bleach and detergent, but it still looks orange. Is there a homemade cleaner for this? Thank you.

  • We received beautiful pristine white high thread count linens for our wedding. We had a pesky mosquito that was annoying us each night. My husband finally spotted it and SPLAT! Blood on the new linens! I took peroxide with a spray top and sprayed the blood stain. It was miraculous! I literally watched the stain disappear before my eyes. I sprayed it once (watched it foam), sprayed it twice (watched it foam again), took a paper towel and barely blotted it, then sprayed one last time. The stain was gone! Absolutely gone! No one would ever know there was ever a stain. This happened one more time and I called my husband over to watch the magic of the science…he was stunned.

  • It also is a quick (not permanent) way to “scare” away fleas, it doesn’t kill them but they don’t like being in the area that has been sprayed with it. I used it to keep them out of certain areas that were highly lived in to keep them away from me and my pets favorite area while I cleaned. I don’t know if it’s the burn or smell that they hate the most, but once sprayed they seem to disappear.

  • I use peroxide in my ears when I feel a cold coming on….you can google it for instructions…took a bottle to mexico and used it in my nieces ears that got clogged with sand from the ocean..it worked

  • Peroxide and mouthwash is great for soaking dentures. However, it can make natural teeth sensitive so use sparingly for teeth whitening and mouthwash. I don’t think I’d dare try it as a sinus wash. If it’s not safe for eyes, it’s not safe for mucas membranes. Also, although it’s relatively inexpensive and may work in a pinch for some cleaning situations, there are other more effective cleaning recipes on Jillee’s website.

  • Jillee, I love this lady as she has improved the life of this old widower. So many helpful ideas that save time and money. Vinegar, Salt and many others. Now Peroxide. If I could just do the 3 second T shirt fold. Keep up your blog and successful battle.

  • When you remove your bridg from your mouth add Peroxide to your cup let stay over night in morning rince clean when washing dirty hands add some peroxide it will buble all imbedded dirt out when you have a sore throuth gargle with some peroxide

  • I use two or three drops in my ears when they feel itchy (allergy) or on the verge of an ear ache.
    I keep an apothecary bottle with a dropper full and ready to go at all times…
    If the bottle with the drops are warmed in a very HOT mug of water it feels much better.

  • to remove SKUNK spray on dog use one 32oz bottle of Hydrogen Peroxide, 1/4 cup Baking soda, and a little dish washing soap apply for 15 minutes, and rinse. Keep away from eyes. You can cut it down in same ratio for a smaller pet. I follow with a shampoo bath. Very effective.. ask me how I know. lol

  • If you are sensitive perhaps you should skip this…if you have hunter cats read on. I have always had cats. A few of them have been VERY successful hunters! They, of course, bring their prey back to their ‘den’ to continue to play with and then kill and eat. More often than not this causes blood stains on the carpet. Hydrogen peroxide to the rescue! I pour it directly on the stain; let it sizzle; mop up with paper towels and repeat. It is very effective. You should test an inconspicuous area first. I’ve yet to have problems with a carpet lightening but better safe than sorry.

  • If you have tile floors you’ll notice how dirty and grimy the grout lines can get, pour a little hydrogen peroxide on it and scrub with a old toothbrush and, wow! Not only will they look nice but they will smell nice too!

    • Yes, it works brilliantly on grout. I never tried hydrogen peroxide on it’s own for this; I make a paste with hydrogen peroxide and baking soda…tooth brush. <3

  • BEST PET CLEANER…….Amazing how you use DAWN & BAKING SODA ALONG WITH HYDROGEN PEROXIDE !! ! ! ! THAT combination I use one large bottle of H.P ,, 2 TABLE spoons of Baking Soda & then One good squirt of DAWN,… GENTLY shake in a bigger bottle cause it will foam over a bit.. My aunt has two dogs who potty on papers in her home & sometimes miss., I pour the formula on it…& put a paper on it and step onto the pee and this mixture takes up EVERY BIT of the urine and removes ALL SMELL.. I don’t even put it in a spray bottle cause I use about a quart a week…Others I have shared this with say that after cleaning after their pets,,especially CATS…..MARKING?? THEY DON’T COME BACK TO THAT SPOT…so they found that spraying their houses at the animals nose level no more cat spray. !! ! !

    • Thank you, Kit. I have 2 cats and 2 dogs. One of my cats is a senior kitty, and frequently “misses” the litter box. I have used the chemical sprays to clean the area, but the cat can always “smell” it anyway. I like the idea of using no harsh chemicals. Thank you! Also, thank you to Jillee for the great job you do!

  • For many years I have cleaned my bathrooms then wiped them down with peroxide…feels so much cleaner using this method for me…and of course I am a retired nurse.

  • Although Peroxide is great for many many things, keep in mind that it will dye any clothing items it comes in contact with. Have used it as a stain remover on white clothing, the stain disappeared, however the peroxide left a yellowish mark on the clothing.

  • I buy hydrogen peroxide with a spray top already attached at Family Dollar. Then I refill it from the larger, cheaper bottles.
    I have a B&B and find all sorts of stains on things and I’ve never found anything yet that HP, Dawn and/or baking soda won’t remove.

  • For those of you brave enough to try it, use Hydrogen Peroxide on open cuts & sores. It will sting, definitely bubble a lot but will thoroughly get rid of germs, etc.
    I have also used it to clean jewellery but the metal mustn’t be plated has to be pure.

    • Please do not use it on open cuts and sores. This is old advice and wound care experts no longer recommend that. It causes the fibroblasts, cells responsible for healing the wound, to be destroyed (along with the bacteria), so healing takes longer.

      • actually, it cleans the wound wonderfully and does not effect healing time. rinse, dab dry with clean wound pad, then cover if necessary. been used for eons and still does the job.

      • If treating children, definitely dilute. I use 50/50 H2O2:H2O. Doesn’t sting and child trusts me next time.

  • I love using peroxide for blood stains. Most of the time it will come right out if it’s a fresh stain. Then I’ll use some baking soda and dawn if it’s stubborn. Only use on light colored fabrics. I always try to keep a bottle on hand. Great for dealing with some of that girly stuff.

  • For blood stains and other stains use Soda, dawn detergent and peroxide. Pour peroxide on stain add small amount soda and dawn detergent. Use small brush and scrub the stain then throw into washer stain will be gone.

  • Doctor told me to pour hydrogen peroxide into my ears to clean the wax out. It popes and bubbles does not hurt and cleans well.lay down with ear up pour in peroxide. Let boil n pop. When done poping have towel handy and turn over and catch. Lie there till drained out and do the other ear while waighting to drain. Works good.
