BEFORE YOU START: Please be careful when handling Hydrogen Peroxide. The tips here are suggestions, and each should be carefully considered before putting into practice.

Health & beauty uses for hydrogen peroxide

Who knew hydrogen peroxide could do more than bleach hair?

1. Whiten teeth

white teeth
Pearly white!

Want whiter teeth? Mix hydrogen peroxide with baking soda until a paste is formed to make a weekly homemade stain remover for your coffee or tobacco-stained teeth.

2. Antiseptic mouth rinse

Make your own mouthwash! Combine 1 part hydrogen peroxide with 2 parts water and swirl around your mouth to help kill any stubborn germs on teeth, tongue and gums that can lead to bad breath - all it takes is 30 seconds of swishing.

This is also recommended by orthodontics for those new to braces. The solution will calm inflammation and ease the pain.

3. Whiten nails

If your nails have been stained from endless nail polish applications, soak your fingertips in a small bowl of hydrogen peroxide.

Rinse thoroughly to reveal cleaner nails and whiter French manicure-esque tips.

4. Clear up acne breakouts

Spots are often caused by bacteria. Germs can be easily spread onto the face when you touch your skin or itch your eyes. Hydrogen peroxide can come in handy as a face rinse as it will kill bacteria and also help dry out any existing spots.

Squirting onto a cotton pad and apply gently to the area. Leave for 5 minutes before rinsing clean.

NOTE: Always do a patch test first.

5. Soften corns & calluses

soft feet
That's better!

Sandals don't look so chic on feet with calluses and corns.

You can effectively soften painful corns and calluses with a hydrogen peroxide foot soak.

Mix equal parts of hydrogen peroxide and lukewarm water before popping your feet inside for 20 minutes.

6. Prevent swimmer’s ear

Swimmer's ear is an infection of the outer ear canal caused by bacteria and fungi. It's common in swimmers as prolonged periods spent in water can break down the skin and allow bacteria or fungi to penetrate.

Like to swim a lot but don’t like the inevitable swimmer's ear syndrome?

Mix equal parts hydrogen peroxide and white vinegar in a small bottle with a dropper lid. Apply a few drops into each ear after swimming to prevent infections from forming.

7. Ear wax removal

Although many of us use cotton buds to clean our ears, they're not actually recommended by professionals as they can easily damage delicate ears drums.

A safer way to remedy built-up ear wax is using hydrogen peroxide. Tilt your head and add a couple of drops of hydrogen peroxide into your ear, wait a few minutes then follow with a few drops of olive oil. After another few minutes, tilt your head the other way to drain out any excess fluid.

8. Treat athlete’s foot

Athlete's foot is another fungal infection, but despite the name, it isn't unique to athlete's alone. The damp environment inside our shoes it what often causes bacteria to form and thrive.

Hydrogen Peroxide has excellent anti-fungal properties, making it a great solution for this common problem.

Make a solution by combining equal parts hydrogen peroxide and water then apply to your feet nightly so it can get to work on fighting the fungus.

9. Relieve ear infections

It can work wonders!

If you’re suffering from an ear infection, help relieve the pain with a few drops of hydrogen peroxide in each ear.

It won't get rid of an infection but it can aid recovery.

Diluted hydrogen peroxide is also a great solution for dogs who have chronic yeast or bacterial ear infections. Mix 1 part hydrogen peroxide with 1 part water and apply to your dog's ear with a cotton ball.

10. Disinfect toothbrushes

coloured toothbrushes
Don't let them get dirty!

When was the last time you changed your toothbrush? If it's been a while, it might be a good idea to disinfect it.

Soak toothbrushes in hydrogen peroxide to zap bacteria and other germs that can be found in the bathroom environment.

11. Treat ulcers

Canker sores, more commonly known as ulcers, occur inside the mouth and are caused by a range of factors from stress to stopping smoking.

They can take around two weeks to heal naturally, so it's worth considering a natural remedy to speed up the process.

Mix 1 part 3% hydrogen peroxide with 1 part water and dab onto the ulcer using a cotton wool pad. Reapply to the affected area a few times each day.

12. Treat colds

Colds aren't often serious, but they can be annoying!

Many people claim to have banished their colds almost instantly by administering a few drops of hydrogen peroxide into each ear.

We'd definitely like to try this one!

13. DIY deodorant

Out of deodorant? Don't panic!

You can whip up a quick DIY version with 35% hydrogen peroxide and bicarbonate of soda. Apply under arms and it will keep you smelling fresh all day long.

14. Disinfect small wounds

Not got your first aid kit to hand?

If you’ve got a small cut or graze to deal with, reach for the H2O2 which is a natural antiseptic.

It can be applied directly to minor wounds to clean away dead tissue and help prevent any infections.

NOTE: Hydrogen peroxide should only be applied once as using it on a wound too much may inhibit friendly bacteria which is essential for the wound to heal.

15. Highlight hair

Get that sun-bleached look without the sun or an expensive trip to the salon! Spray hydrogen peroxide over damp hair and let it soak in for 10 minutes, then rinse out. If your hair naturally lightens in the sun then this will work well. Make sure you do a strand test before you commit.

16. Clean contact lenses

Running out of lense solution can be a nightmare! Dirty contacts can be a real danger to the eyes and may cause infection.

When you've run out of lense solution, the best way to clean your lenses is with hydrogen peroxide. It helps get rid of the common build-up of proteins that can diminish contact lenses over time.

Use H2O2 as a quick, cheap alternative to expensive solutions, but always use it sparingly otherwise it too could damage eyes.  Read LiveStrong's article on how to clean contact lenses before you attempt to do it.

Stain removal's never been easier!

For 'organic' or 'natural' stains such as coffee, blood, wine and sweat, there's nothing better than hydrogen peroxide.

If your seasonal wardrobe has been in storage for a few months, you can help de-funk that musty smell by mixing hydrogen peroxide with vinegar and spraying onto fabrics.

Considering what our toilets have to put up with, it's no doubt they get a little grubby from time to time.

32. Disinfect cutting boards

Where to buy hydrogen peroxide

Like the sound of some of the uses for this cheap budget product? You'll need some hydrogen peroxide to get started.

Depending on what you plan to use your hydrogen peroxide, you may need several different types. 3% hydrogen peroxide is the most popular and cheapest, however it contains other ingredients which can be more harmful - it's less 'pure'. 35% hydrogen peroxide, or 'food-grade' hydrogen peroxide, is recommended wherever possible.

    PLEASE REMEMBER THOUGH THAT IF YOU DILUTE IT AND STORE IN THE BOTTLE IT WILL LIBERATE OXYGEN AND THE BOTTLE CAN EXPLODE. Best to make up a small amount at a time. Not being alarmist, have made this mistake myself. Tip the peroxide in a cup or similar, dilute it there and after use discard any diluted solution..Please!

    1. Author Joanne A on October 15, 2018 at 10:31 am

    Is it true that mixing Hydrogen Peroxide and baking powder will get rid of perspiration crusty buildup in the under arm area of shirts?

    1. Author Joanne A on April 12, 2023 at 5:21 pm

      Mixing hydrogen peroxide and baking powder may help remove sweat and crusty buildup in the underarm area of shirts, as hydrogen peroxide can break down the proteins in sweat stains and baking powder can neutralize the acidic odour and loosen the stain. However, it is essential to test this solution on a small, inconspicuous area of the fabric first to ensure it does not cause any damage or discolouration.

    I have recently been into my loft to recover baby clothes which have been wrapped and boxed for several years. I was amazed at how well most of them have kept some look brand new. The odd ones (some unworn) however have spadmodic yellowing. This has happened on various fabrics. Some are wool others are typical romper suite material etc. Some of them look like iron mould spotting which has amazingly washed out with a little soaking in washing powder others are stubborn but I admit I have only tried a few as I preferred to seek help before setting in any stains which could have been removed with advice. Please can you help me????

    1. Author Joanne A on April 14, 2023 at 12:10 pm

      To remove yellowing and spotting from baby clothes, try soaking them in water and white vinegar, using a stain remover, baking soda and water paste, or using a gentle, pH-neutral detergent. Always test any stain removal method on a small area first, and avoid using hot water or bleach.

    If I used it on my carpet do I dilute it and what’s the ratio

    1. Author Joanne A on January 20, 2023 at 12:14 pm

      Hydrogen peroxide can be used to clean carpets, but it should always be diluted with water before use. A standard dilution ratio is 1 part hydrogen peroxide to 3 parts water.

  17. Author Josie G on April 12, 2023 at 11:06 pm

    Great article, thanks! I've been using hydrogen peroxide for decades and still learned some new uses from this article. It's also great for helping to heal any new piercings. Just dilute 6% HP with equal amount of water then soak a cotton bud and apply to piercings (or dip your pierced bit/s in a small bowl of the solution). It fizzes and you'll see all the gunk come out. No need to rinse. Repeat daily. It's also good for clearing up nail fungus. Again, dilute 6% HP with equal amount of water and soak nails in a bowl if you can, or apply with a cotton bud soaked in the solution. No need to rinse. Repeat twice weekly, or weekly is fine too. Finally, it's also good to apply to teeth to clear any hidden gunk. Same solution as before, applied with a soaked cotton bud (you may need more than one). Don't be alarmed by the fizzing action - it's fairly entertaining :) Spit the residue into a tissue and keep going for a few minutes, maybe with a new cotton bud as the more they get soaked the more they tend to disintegrate. Afterwards rinse & swoosh your mouth to get rid of any residual debris.

    1. Author Joanne A on April 13, 2023 at 12:13 pm

      It's essential to consult with a healthcare professional before using hydrogen peroxide for medical purposes, especially for piercings. In addition, using hydrogen peroxide on teeth should be done cautiously to avoid potentially damaging tooth enamel.
