Coming Out Of The Medicine Cabinet…17 Alternative Uses for Alka-Seltzer!

Tis the season for over-indulgence. If you happen to indulge in a little too much food or drink this holiday season…a couple of Alka-Seltzer can be your best friend. But did you know that these fizzy little tablets can do a lot more than ease a hangover or an upset stomach?

Alka-Seltzer is made up of aspirin, citric acid, and baking soda which make it not only useful for medicinal purposes but a great cleaning product as well!

Here are some OTHER uses for the “plop, plop, fizz, fizz you might not know about (I sure didn’t!):

Safely Unclog A Drain

A great natural solution for unclogging the drain!  Just drop four Alka-Seltzer tablets down the drain, followed by a cup of white vinegar and allow to stand for about ten minutes. Flush with a pot of boiling water. Doing this on a regular basis can help keep that drain clear. This also works to deodorize the drain.

An All-Purpose Cleaner  

Alka Seltzer can also be a good all around cleaner.  Plop three tablets into 8 ounces of warm water. Once the fizzing stops, dip a sponge in the water (or you could fill a spray bottle) and wipe down counters, tiles and tubs. You can even place some in your sink and use as mop water. Just add five tablets to one half gallon of water.

    I’ve been using denture tablets for about a year or so now to do a lot of these cleaning tasks. It’s good to know that Alka Seltzer will do the same thing, so now when I need a new box of “bubbly” I can check to see which one is the cheapest that week. You got me on the “Cure Urinary Tract Infections” one. Does it really CURE it or mask the symptoms until you can get to a Dr? How often should you take it?

    Thanks to Jillee I feel like I’ve learned something new everyday!

    • Katherine says

      It can only mask the UTI symptoms because a UTI is caused by bacteria. Alka Seltzer doesn’t contain antibiotics. It says it contains aspirin, so it is only going to help with the pain.

      • dani says

        Actually, baking soda is a common remedy for uti’s. I’m sure the aspirin helps with the pain, though.

      • frances says

        Uti can only exist in an acid environment, alka seltzer removes the acid, hence uti goes away if taken at the early stages

      • tina says

        apple cidar vinegar is the very best thing for uti if you wake up w uti symtoms take abt a shot of vinegar w a glass of water as soon as you get up thn again befor you go to bed the next morning you will fill much better i usually do it for abt 2days thn whn im beter i usually at least drink vinegar and water 1ce a wk because i drink alot of DT MT DEW

    • Rachel Bennett says

      Also, the citric acid (vitamin C) will help increase the acidity of your urine, which helps kill the bacteria. You could take some Vitamin C by itself, as well. I am a nurse, and took care of a lady once who was VERY prone to UTI’s and her doctor had told her to take 4000 mg per day to keep them at bay. You cannot overdose on vitamin C, since it is water soluble — your body gets rid of the excess in your urine! It won’t hurt you and it might help you avoid UTI’s. If it doesn’t work, you can still go to the doctor. The vitamin C will not have hurt anything.

      • Chefmary says

        As a nurse, I was also taught that vit c was benign. I advocated for large doses of vit c especially in the cold season. Until…. My husband got kidney stones secondary to vit c and green tea intake. In big doses, vit c will precipitate out as stones. So… If you take large doses of vit c, don’t drink green tea.

      • Mitch says

        Yes same thing happened to me. I was told “you can’t take too much, you’ll just pee it out”. I was getting a lot of colds so I started taking massive amounts of Vitamin C daily. About 6 months after I started the high dose Vitamin C regimen, I had a kidney stone. After some research I realized it was probably the Vitamin C. 10 years later and no stones other stones.

      • Lily says

        Your reply makes it apparent you’ve never seen anyone overdosed on vitamin c. Diahrrea, vomit, dehydration, and abortion are common in vitamin c overdoses. Some nurse you are!

      • Kim says


        I found your reply interesting. However, I would strongly urge you not to give general medical advice online as it may give readers the impression that they do not need to seek medical care. This is a friendly post, from one nurse to another.

      • Ram says

        It has been specifically proposed that megadoses of vitamin C increase oxalate production (thereby increasing the formation of renal stones); competitively inhibit renal reabsorption of uric acid; enhance the destruction of vitamin B12 in the gut; intensify the enteric absorption of non-haem iron, thus leading to iron overload; result in mutagenic effects; and increase vitamin C catabolism that would persist after returning to lower intakes of the vitamin (Combs, 1992). These and other possible effects of high doses have been reviewed by Hornig and Moser (1981) and Rivers (1989), who conclude that ingestion of even massive amounts of vitamin C (up to 10 g/day) does not usually constitute a health risk for humans. Nevertheless, large doses are contraindicated in cases of renal insufficiency, chronic haemodialysis, unusual forms of iron overload, and in oxalate stone formers.

      I haven’t tried the UTI cute, but my grandmother gets them all the time, and I will be checking this out! It makes perfect sense if you think about alkaline vs acid environments in the body. Wish I knew this sooner. Thanks!

  2. Deb says

    For stinky feet, pour warm water in container and add 2 tablets and soak feet for 3-5 minutes. Alka Seltzer cold plus works best!

  3. says

    Great hints. Especially the one for the coffee maker. You would be able to treat a hangover and have your cup of coffee at the same time. May not taste that good though.

  4. Vicky T says

    I have done several of these using denture cleanser tabs. I have no doubt these work but I certainly would try using “store-brand” or generic brands since Alka-Seltzer is quite expensive, especially when used in large amounts. Still do love the uses though. Great!!

  5. Casey says

    I used them when I was a teenager and had a retainer. I always felt weird buying them at that age, but they sure worked!

  6. says

    I make my own fizzy tablets when I’m making bath bombes! Just mix 2:1 Baking soda and citric acid, spritz with enough water to make it hold together, and pack into small ice cube tray / candy mold. No asprin, and cheaper if you already have the citric acid!

  7. CTY says

    Keep out of reach of Children: Somehow once as a kid, one of us got hold of some travel size two packs. We broke them up and took turns foaming at the mouth like a rabid dog. My brother was the best (as always), he put a whole one in his mouth because he wanted to foam the most, & kept his mouth shut. Yep, you guessed it- it came through his nose.
    Since the digital age–where can I get film canisters?
