21 Uses for Hydrogen Peroxide

Hydrogen Peroxide Uses.


Hydrogen peroxide (H202) is a clear liquid that looks exactly like water, but is a bit thicker. The over-the-counter types that most consumers are able to purchase is actually only 3% hydrogen peroxide (and 97% water). It is safe to use, but the pure stuff can be very dangerous if not used correctly.

I love using hydrogen peroxide around my home. It is very well known for it’s antibacterial qualities and that’s mostly what I use it for – but there are other uses as well.

Here are 21 ways that you can use hydrogen peroxide:

  1. Add about 2oz. of hydrogen peroxide to your dishwasher detergent for a bit more sanitizing.
  2. Use a 50/50 mixture of hydrogen peroxide and water as a mouthwash to freshen breath and kill bacteria.
  3. Create your own toothpaste by creating a paste out of hydrogen peroxide and baking soda. The hydrogen peroxide also acts as a whitening agent, so your teeth will be clean and white.
  4. Wash fruit & veggies to remove dirt and pesticides. Add 1/4 cup of hydrogen peroxide to a sink almost full of cold water. After washing your produce, rinse thoroughly with cool water.
  5. Pour a bit of hydrogen peroxide on your clean cutting board, let it sit for a few minutes and then rinse clean with cool water.
  6. Wipe out your refrigerator using hydrogen peroxide.
  7. Soak your sponges for about 15 minutes in a 50/50 mixture of hydrogen peroxide and warm water. Rinse the sponges thoroughly when you’re done.
  8. Remove baked-on food from pots and pans by creating a paste out of hydrogen peroxide and baking soda. Rub into your pots/pans and let sit for an hour or two. Scrub lightly and wash as usual.
  9. Pour half a cup of hydrogen peroxide into your toilet bowl, let stand for 30 minutes, then scrub clean.
  10. Remove stains from clothing by soaking in 3% hydrogen peroxide for about 15 minutes. Then, wash as usual.
  11. For whiter whites, add one cup of hydrogen peroxide to a load of white laundry.
  12. Keep a small spray bottle filled with hydrogen peroxide and regularly spray doorknobs and light switches to keep them clean and germ-free.
  13. Hold one cap-full (the little cap that comes with the bottle) of hydrogen peroxide in your mouth for about 10 minutes and then spit it out. Do this every day for a few weeks and your teeth will be whiter. Only do this for a few weeks. Extended use could do more harm than good.
  14. To prevent wilting, spray a mixture of 1 tablespoon hydrogen peroxide and 1/2 cup water on lettuce, drain, cover and refrigerate.
  15. Apply a bit of hydrogen peroxide on pimples to help get rid of them.
  16. Eliminate bacteria in your shower/bathtub by spraying with hydrogen peroxide.
  17. Add 1 cup 3% hydrogen peroxide to the rinse cycle when washing your shower curtain liner. This will help to remove soap scum and mildew. Here’s how I wash shower curtain liners.
  18. Add musty towels to a mixture of 1/2 cup hydrogen peroxide and 1/2 cup vinegar. Let stand for about 20 minutes and then wash as normal.
  19. Kill weeds by spraying with hydrogen peroxide.
  20. Add about 2oz. of 3% hydrogen peroxide to your bottle of dish soap for extra cleaning power.
  21. Get rid of underarm stains on your shirts by rubbing the affected area with a mixture of 1 part dish soap and 2 parts hydrogen peroxide. Let it sit for about 1 hour and then rinse in cold water.

Do you use hydrogen peroxide? What do you use it for?

    It also works well for removing organic stains from granite counter tops. Make a paste out of corn starch and hydrogen peroxide. Cover the stain with the paste and cover with plastic wrap. Tape the edges and leave for 24 hours. Wipe clean. *Always do a test spot in an inconspicuous area first*

  2. Mimi

    Does it work on white erase boards markers? My kids got it all over their clothes… Can’t seem to get rid of the stains…

  3. Heather R

    Great tips! I usually use it for cleaning. I clean with vinegar and then follow over the surface with the peroxide for disinfecting.

  4. Carla

    I once did tip #3 (the toothpaste) and my gums turned white. It was kinda scary, but luckily it was only temporary.

  5. Karen

    Actually hydrogen peroxide is NOT a good idea to use on wounds, pimples or in your mouth. That information is outdated. We now know that hydrogen peroxide actually damages healthy tissue. I would not recommend it for any of the uses you outlined for use on the body.

      Agreed.. also, baking soda is NOT recommended as a toothpaste because you can erode the enamel on your teeth permanently! If you do want to use baking soda on your teeth, use it once in a while only!!!

    Someone sent me an article on this several years ago and have been using it for several of the applications metioned in the article. Love it!!!

    This is also amazing at removing blood stains from clothing and it doesn’t (bleach) the colours. Great tip if you have ever had the kids scuff a knee or elbow among other things.

    I mix a cup of hydrogen peroxide with 2 tablespoons of the blue Dawn and I use that to scrub my carpets – we have two dogs and they love sitting on the landings – gets out all the stains – unfortunately if your carpet is old (like mine is) you will have to scrub the ENTIRE area as the area you clean will most likely end up cleaner than the rest of your carpet

  9. Olivia

    Doesn’t peroxide bleach out carpets and fabrics?? I experienced bleached spots on pillow cases and towels when my daughter used it for pimples. Why did it happen to me? They were ruined. Any ideas?

    • Cassie Howard

      It depends on the material, Olivia. You have to test in a very small area first, to make sure it will not ruin the fabric.

    I use a mix of peroxide, baking soda, and a few drops of liquid dish soap to spray my furniture keeps smelling clean, also use the same mixture on my dog after she gets sprayed by a skunk, works wonders.
