Magical Uses of Hydrogen Peroxide

Written by The Ready Store

Hydrogen peroxide can be a great tool in your emergency pack. It has hundreds of uses that can help you clean and disinfect in any situation.

Hydrogen peroxide has the chemical property


It is a strong oxidizer and is often used as a bleach or cleaning agent. You can also use it to whiten clothes, fight infections, make your own toothpaste, etc. Check out these ideas below on how you can use hydrogen peroxide for multiple purposes around your home.

Purchasing Hydrogen Peroxide
When you’re purchasing hydrogen peroxide, you have a few different options. Hydrogen peroxide comes in a few different grades, the most common being 3.5% Pharmaceutical grade. This is sold in your local drug stores and supermarket and should not be ingested.

6% grade is used in beauty shops to color hair and shouldn’t be used internally. Higher grades like 30-32% are used to clean electronics and cars.

35% grade is the only grade that is approved for internal use. It’s used in the production of eggs, cheese and other food items.

The only other grade higher than 35% is 90% and is used as an oxygen source for rocket fuel! Ya, don’t eat that either.

Remember that using items over again and finding multiple uses is a great way to save money and help you become more self-reliant and self-sufficient.

Whiten Clothes
Add a cup of peroxide to your laundry as they wash. It gets rid of stains in clothes and carpet. Just pour directly onto the spot, let it sit for a few minutes and then rub and rinse with cold water. Repeat if necessary.

Foot Fungus
Have a nasty itch on your feet? Hydrogen peroxide can help. Simply spray a 50/50 mixture of hydrogen peroxide and water on them every night and let dry.

Infected Cuts
Soak the cut in a mixture of 3-5% hydrogen peroxide for five to 10 minutes several times a day. People have reported that soaking their wounds in hydrogen peroxide has healed gangrene, boils, and skin infections.

Sinus Infections
A tablespoon of 3% hydrogen peroxide added to 1 cup of water (non-chlorinated) can be used as a nasal spray. For more severe sinus infections, increase the amount of hydrogen peroxide in the mixture.

Toothpaste & Mouth Care
Hydrogen peroxide is a great tool for mouth care. You can use it to create mouthwashes, relieve toothaches and make your own toothpaste. Start with a bit of baking soda and slowly add hydrogen peroxide until it creates a paste. Hydrogen peroxide is antiviral, antibacterial and anti-fungal, so it makes a very efficient toothpaste. However, some people have reported that the hydrogen peroxide reacts with amalgam fillings in their mouth, so be careful.

Food Cleaner
Some people add ¼ cup hydrogen peroxide to a full sink of cold water and allow their vegetables to soak and clean before preparation. You can also rinse your meat off before cooking.

Clean Mold
Use a hydrogen peroxide spray to wipe up mold in the fridge or in your house so that it doesn’t spread. Since hydrogen peroxide is anti-fungal and antibacterial, it should stop the mold in its tracks!

    Peroxide and baking soda, a little dish soap, mixed together will get rid of cat urine smell and skunk. I have used this successfully for both.
    Let it stay on the dog as long as you can. Rinse well, and repeat if needed. Dog shampoo works great instead of dish soap.

    Did you mean 3.5 in this statement?: “35% grade is the only grade that is approved for internal use.” Must have left off the decimal point by accident. If so, better correct that otherwise people will strip their throats and stomach and burn the skin off their tongue.

    Or, are you referring to Food Grade H2o2 35%. If so, it must be diluted with distilled water to a mix that is less than 3% H2O2. Some people will need to make it a 1% solution or less if one has a hard time taking it in at 3% solution until one gets used to it. Then increase the amount to a stronger solution slowly over a period of time.

    I use a 3.5% Hydrogen Peroxide to “boil out” ear infections. It is also helpful to those who have problems with water left in the ear after a shower or swimming. Using an eye-dropper, I get the peroxide in the dropper, warm the dropper tube under warm running water and place 6 to 8 drops in the affected ear. Works great!!!

    Just an additional thought about the use of Hydrogen Peroxide to “CLEAN MOLD”. I put the 3.5% solution in a spray bottle and give my bathroom a going over – base of shower, around toilet, sink, baseboards. I go around the metal strip between the kitchen sink and the counter-top. (You won’t believe what foams out) It is safe to use on metals – unlike bleach. I go around baseboards in my closets.

    Don’t wipe it dry – let it evaporate. Keep it up for a week or two and see how fresh the house smells without that bleach odor.

    Hydrogen peroxide has a shelf life, so make sure you rotate out your stock.
    Note: the article references the use for “infectious cuts” and not for cleaning everyday scrapes & wounds. It is best to use clean water for wound flushing. AFTER the wound starts to heal, use HP to help fight infection.

    Thank you Ready Store for putting out this info about Hydrogen peroxide. I store many bottles of it and use it – a lot!

    Periodically soak your toothbrushes in a cup of peroxide to keep them free from germs.

    After rinsing off your wooden cutting board, pour peroxide on it to kill salmonella and other bacteria.

    Clean your counters and table tops with peroxide to kill germs and leave a fresh smell.Simply put a little on your dishrag when you wipe, or spray it on the counters.

    Use it to cean your mirrors – no smearing!

    Bleach was invented in the ’40’s. It’s chlorine and it was used to kill our troops.
    Peroxide was invented in the ’20’s and was used to save and help cleanse the needs of our troops and hospitals.

    Hydrogen peroxide can be used to clean the foot nails’ fungus. Psoriasis causes brown patches on foot with itching. Scaling and brown color will diminish over four to six months when Hydrogen Peroxide (3.5% or less Pharmaceutical grade) is used in addition to Psoriasis skin itching. Take a cotton ball with Hydrogen Peroxide and smear it on the skin.

    Caution: Do not use on sensitive skin with blisters. Do not use on face and other sensitive areas other than foot.

    We use it to clean the blood out of a washcloth, clothing, and other fabrics. My wife had a cut on her foot that bled profusely. Blood got all over the shower curtain, bath mat and vinyl flooring. EMS came and stopped the bleeding, but by the time they left and I started cleaning, much of the blood had dried. This was going to leave several large stains and possible disposal of items. My wife put HP on all the stains and they came out. Unbelievable!

    My son was fifteen when he burned his forearm on a hot engine of a go-cart, while pushing it up a gravel road, uphill. He had the area burned about the size of three fingers width and as long. The inside varied from a hot red around inwardly charred with layers missing. So at least part third degree burn. I was an LPN. Anyway, I asked if he would like to go to the ER…to which he said,”Negative.” I used Hydrogen Peroxide on it for 3 seconds…then we rinsed with cold well water. We used virgin organic coconut oil on a light dressing over it. Several times a day we did hydrogen peroxide (3% store bought at Walmart) for 3 to 10 seconds then coconut oil around edges and on dressing bandage so it would skin. Excellent granulation. Healed fine with no skin grafts nor infection. No scar!

    I used it to heal up a recluse spider bite by that very idea. It destroys the infected skin and stops the infection from spreading. Once the infection is stopped, the skin will grow back. Mine did and I have used it this way 3 times from those bites. It does NOT slow the healing process but does stop the infections growth.

    You said: “6% grade is used in beauty shops to color hair and shouldn’t be used internally.”, that is incorrect, hair salons never use 6%, they use 10%, 20%, 30% and 40%, it is ALWAYS mixed with either a product to color or a powder bleach, it is not meant for straight use on skin and never for internal use.

    The reason the 3% sold for external use and the ones sold for salon use is never to be ingested is the manufacturers add stabilizers to it to keep the strength consistent, these stabilizers are toxic for internal use but fine for external use, each time you open a bottle and expose it to the air, it loses some of of its strength.

    You said: “35% grade is the only grade that is approved for internal use.”, well that is almost correct, the only kind you should ever use internally is FOOD GRADE hydrogen peroxide, it often comes in 35% strength, BUT that should NEVER come in contact with skin or be ingested at that strength, it MUST BE DILUTED, it will burn your skin and mouth if you do not dilute it. I buy 35% food grade H2O2 and dilute it for internal and external use.

    There are lots of good uses for H2O2, a great book I have is called “The One Minute Cure”, it is available on Amazon, it gives all the dilution formulas and the uses of food grade H2O2.

    I worked with 97% HP in the Air Force at Vandenberh AFB Calif. It was used as an oxidizer that passed through a silver screen in the Blue Streak missile. It was the most volitical, scary agent we were exposed to. Highly unstable if spilled and would explode and burn everything in its path. 3% is safe on the skin and has many uses.

    I keep several spray bottles filled with peroxide, and several filled with vinegar. And, I use them to clean/sanitize just about anything and everything (from countertops to vegetable sprays). Years ago, I read about a study trying to determine how effective these two items were at killing germs. I don’t recall which was more effective than the other (individually). But, I do recall that one followed by the other (regardless of the order), killed 100 percent of the bacteria they tested against (and, they tested against some pretty bad bugs).
    It’s cheap and it’s effective. And should a slight bit of residue remain on the cleaned produce (after rinsing), I know it’s not toxic.

We also use a 6.5% grade in our hot tub instead of bromine or chlorine. 1 3/4 C per 500 gallon. Super! No problem with trying to get the balance right. I was told by my tub guy, years ago, to treat every week…we found that we did not have to treat that often to keep the water clean and bright. We have used this formula on our tub for most of the 21 years we have had it and it is still going strong. It does not damage any of the parts on the tub and is more gentle on your body.

I finally settled on a simple concoction of 1/3rd each, with a few drops filling one ear canal at a time; and allowing it to sit for 5 min. If you catch it early, this simple and readily available triple combo (or even just any 2, if that’s all you have available) always corrects it within a couple of days.
