Hydrogen Peroxide

Updated: 10/10/2019

Hydrogen peroxide is kind of a super-chemical. It’s dangerous enough to kill all the cells in an area but safe enough to put on your skin or inside a few cavities. Using hydrogen peroxide only takes a minute or so of preparation, as adding water to it is usually the only step needed. It’s also something that can be taken anywhere and easily adapted to fit your specific situation. If you have some hydrogen peroxide laying around, be sure to try some of these 18 great uses for hydrogen peroxide.

18. Use Hydrogen Peroxide to Keep Your Bathroom Clean

Clean Bathroom

Hydrogen peroxide works great to keep the surfaces in your bathroom clean, even after months of neglect. Soap scum building up in the bathtub is notoriously difficult to remove, but by simply spraying the tub with hydrogen peroxide and letting it sit for 30 minutes, the scum can be very easily removed without all of the tedious scrubbing. Hydrogen peroxide can also be used to effortlessly clean your toilet bowl by letting the bowl soak in the chemical before eventually flushing and wiping the bowl completely clean.

17. Can Give You Great Skin

Great Skin

Much like an astringent, hydrogen peroxide can give you great skin. Using hydrogen peroxide as a face wash can thoroughly clean your pores, which will end up ridding you of all current acne and help prevent you from getting any more. For a face wash, the type of hydrogen peroxide you use should be no more than 3%. It may help to wash your face normally first, dry your skin, and then rinse again with hydrogen peroxide, as dry skin will absorb the chemical better.

16. Fight Most Bodily Infections

Fight Infections

Since hydrogen peroxide kills most of what it comes into contact with, it is able to fight off most bodily infections pretty handily. For most areas of infection, simply allowing the area to come into contact with hydrogen peroxide for a short amount of time can be enough to rid the area of infection. For something internal like the flu, try putting three drops of hydrogen peroxide in each ear (it has to be both)  and letting it sit in there for at least 10 minutes before draining.

15. Change Your Hairstyle


As a general rule, it is good to avoid letting hydrogen peroxide touch your hair on a normal day. If, however, you want to change your hairstyle, it may be a cheap and good idea to splash your hair with a little of the chemical. Adding highlights to your hair is a very easy process. Simply spray some hydrogen peroxide on your damp hair using a spray bottle, let it sit for 15 minutes, and rinse it off in the shower for brighter hair.

14. Fix Your Feet

Foot Soak

Much like how hydrogen peroxide can give you great facial skin, it can also make your feet smoother than they have been in a long while. Skip your next pedicure at that expensive place you normally go to and try to do one yourself. It doesn’t take long and is very simple to do. Allowing your feet to soak in warm bathwater and hydrogen peroxide for around 30 minutes will leave your feet looking very clean, remove any stench, and make them very smooth.

13. Clean Your Toothbrush

Clean Toothbrush

For something we put in our mouths at least every morning and night, toothbrushes are not something that we normally clean. Toothbrushes usually sit out on the bathroom counter, unsheathed and open to all types of bacteria, including those that come from an open flushing toilet. If you are worried about having a dirty toothbrush, try soaking your toothbrush in a cup of hydrogen peroxide for at least 30 minutes. The soaking should ensure that your toothbrush is clean and ready to go.

12. Get Rid of Earwax

Get Rid of Earwax

Earwax is something that we all have to deal with, but it doesn’t always have to be a problem. Though most earwax can be eliminated by simply using a tissue, there is still hidden earwax that may not be cleared out so easy. Since using q-tips is heavily frowned upon, try adding a few drops of hydrogen peroxide and olive oil to your ear to clear out excessive earwax. You may have to wait a few minutes before it fully liquefies and becomes easy to drain.

11. Purify Your Humidifier


Using a humidifier in your room can provide many benefits, such as better sleeping habits, a soothed throat, and an overall cleaner breathing environment for you to live in. Over time, however, the water in the humidifier can end up containing plenty of harmful bacteria that will end up growing mold in the water and contaminating the air around you instead of purifying it. Luckily, this can easily be fixed by adding a pint of hydrogen peroxide for every gallon of water that ends up in the humidifier.

 10. Hydrogen Peroxide Can Kill Nail Fungus

Nail Fungus

Nail fungus is caused by exposure to warm and damp environments and allowing fungi to grow uncontrollably in the nail bed. At the start, nail fungus can start as a simple yellow or white spot underneath the fingernail, but can quickly grow into a serious condition that can cause the nail to discolor and possibly break altogether. Luckily, a 50/50 mixture of hydrogen peroxide and vinegar can kill the fungus. Just soak the nail in the mixture for a short amount of time and allow it to dry completely before clothing.

9. Hydrogen Peroxide Can Prevent Swimmer’s Ear

Swimmers Ear

If you swim a lot, the possibility of getting swimmer’s ear may be something that you are concerned with. Swimmer’s ear is an infection of the outer ear canal that is caused by water lingering in your ear long after you have returned to dry land. Swimmer’s ear can normally be fixed by using special ear drops, but if you are unable to obtain some, you can just use hydrogen peroxide. Pour a few drops in each ear that is affected and eventually the infection will disappear. Try using this remedy as a preventative measure for best results.

8. Use Hydrogen Peroxide to Treat Your Corns and Calluses

Treat Corns & Callus

For many people, the sight of corns on your feet can be very bothersome and possibly painful. Calluses can also cause insecurity regarding how a person feels about their appearance. There are many ways to remove corns and calluses from your hands and feet, ranging from inexpensive to expensive, but one simple and cheap way to remove them is by using hydrogen peroxide. Soak your feet in a mix of hydrogen peroxide and water, and the corns and calluses should be gone in no time.

7. Use It to Heal Boils

Skin Boils

Boils are not usually something that people like to talk about, as they can be embarrassing, but they are definitely something that is natural and easy to eliminate. Boils are simply a skin infection that starts in a hair follicle or oil gland. Most boils can heal entirely on their own if given the chance, but if you are absolutely determined to get rid of them, hydrogen peroxide is once again your go-to remedy. Soaking your boil in a mix of hydrogen peroxide can cleanse the boil and eliminate it entirely if done correctly.

6. Hydrogen Peroxide Is Great for Removing Organic Stains

Remove Stails

If you have a pesky organic stain that just won’t seem to go away in the washing machine no matter what you do, it won’t hurt to try one more approach. Organic stains like blood, sweat, wine, or other substances can potentially stick around until it is time to trash the clothing. In order to get a few dozen more uses out of your clothes, try adding a cup of hydrogen peroxide to your next wash load and see if you can tell the difference.

5. Use Hydrogen Peroxide as a Sinus Cleanser

Sinus Cleanse

Don’t let the upcoming allergy season ruin your day and keep you sniffing and clogged up for hours on end. Sometimes, getting a nasal spray or another over-the-counter remedy can be too expensive or time-consuming to purchase. If you are running low on funds or just don’t have the time to grab it at the store, try cycling some hydrogen peroxide through your nasal passages to clear them out. For best results, you may want to test it out on a day when you don’t have much to do to see if it’s right for you.

4. Hydrogen Peroxide Can Clean Your Floors

Cleaning Floors

Looking at your light-colored carpet can sometimes seem like a painful task. You don’t remember spilling anything on your carpet, yet you have discovered multiple stains of varying colors. As you probably know by now, removing stains from the carpet is no easy task. Luckily, if the usual methods don’t work, you can always try spraying hydrogen peroxide onto the stains. The first time you do this, however, it may be wise to spray an area that is not easily visible, as it may not come out exactly how you want it.

3. Hydrogen Peroxide Will Make Your Lunchbox Fresh Again


After bringing your lunchbox to work daily or simply leaving it in the car for too long, it’s possible that your lunchbox has started to have its own unique odor. To avoid your co-workers giving you an assortment of strange glances when they smell your lunchbox, try spraying your box with a bit of hydrogen peroxide, let it sit for a bit, and then wipe it off. When you are done, it should be as clean as when you got it.

2. Use Hydrogen Peroxide to Clean Your Cutting Boards

Clean Cutting Board

Depending on what you normally cook, it could be unsafe to have a dirty cutting board sitting around your kitchen. For starters, if you only have one cutting board in your kitchen for all-purpose use, it is possible that you are cross-contaminating your food and putting yourself at risk. Secondly, it is very hard to clean a plastic cutting board, even if you use a dishwasher. Before the next time you cook, try spraying the cutting board to kill any possible leftover germs.

1. Use It to Clean Your Teeth

Clean Your Teeth

One very beneficial property of hydrogen peroxide is its ability to very effectively clean your teeth, soothe toothaches, and clear up bad breath. In fact, hydrogen peroxide is already present in many toothpaste brands. Brush and floss your teeth as you normally would, but instead of using a standard mouthwash, rinse your teeth with a small amount of hydrogen peroxide and water. This process is so powerful that you will want to restrict this to only three times a week, as this prevents your mouth from forming natural barriers to bacterial ailments.
