Quick Tip : Disinfect with Hydrogen Peroxide

Disinfect Safely with Hydrogen Peroxide - Clean Mama

If you’ve been reading here for any length of time, you know that I love making my own cleaners and coming up with natural ways to clean just about everything.  It occurred to me that I haven’t shared on the blog one of my favorite ways to disinfect the gross stuff around the house (I have some hydrogen peroxide tips in my book, The Organically Clean Home).

Use a Sprayer and the Hydrogen Peroxide Bottle - Clean Mama

Hydrogen Peroxide

What is it?  Its chemical compound is H2O2 – water and oxygen.  It’s a colorless and odorless liquid (it looks like water) with non-toxic whitening (bleaching) properties.  These same properties are also EXCELLENT at killing germs.  It’s typically sold at a 3-6 percent dilution.

How can it be used?  Because of its non-toxic-ness it can be used to disinfect toothbrushes, clean wounds, lighten hair, and CLEAN!

Where can it be used to clean?  Bathrooms and kitchens and laundry rooms – it’s especially good for disinfecting, mold removal, and stains on white clothing.

Are there any precautions?  Hydrogen Peroxide is unstable when it comes in contact with light so you need to keep it in the original brown bottle.  If it comes in contact with colored clothing, carpet, towels, etc. it will bleach the fibers.  It also has an acidity of 11.75 so DO NOT use it on stone (granite, marble, etc.) as it will etch the surface over time.

Where can I find it?  Target, Wal*Mart, any pharmacy and Amazon.

How can I use it?  Use straight out of the bottle if you’re pre-treating a stain (on white clothing).  Mix up with a little baking soda for a cleaning paste, scrub and rinse clean.  This works great for icky grout.  My favorite method? Simply put a sprayer on the bottle, spray on a surface that needs disinfection, let it sit and then rinse clean.  If you want to give germs the one-two punch, you can spray a surface with hydrogen peroxide and follow with white vinegar.  Let it sit and rinse clean.  This is a very potent combination and the two ingredients should NEVER be combined in a container, always keep them separate.  (Personally, I am fine with just the hydrogen peroxide and I don’t spray one after the other.)

Spray on Cutting Boards - Clean Mama

Spray on cutting boards – I only do this if I’ve cut up raw poultry or meat – and run through the dishwasher or hand wash.

Spray in Kitchen Sink to Disinfect - Clean Mama

Spray in the kitchen sink to disinfect – let it sit and rinse clean.  I always spray quite a bit in the drain part to disinfect the drain and garbage disposal area.

Spray Bathroom Sinks - Clean Mama

Use it in the bathroom to disinfect toilets and sinks.  Spray liberally, let it sit for 10 minutes or so and wipe clean.

If you’re using a cloth to wipe surfaces down after spraying with hydrogen peroxide, make sure that it’s white so you aren’t bleaching out any colored cloths.  The Clean Mama Home white bar mops work great!

    I read in a book once that they did a study and if you spray vinegar,followed by spraying hydrogen peroxide and let sit, it disinfects as well as bleach! Thanks for the tips! 🙂

  2. I read somewhere about using Hydrogen peroxide mixture to spray in shoes to get rid of odors. I made a mixture and used it and it worked like a charm, But I have forgotten the combination, I also wanted to know if you could use a few drops of an essential oil like orange, lemon etc without making any negative changes
    Love reading your tips

    • Sorry Judy, I’m unsure of that mixture and I wouldn’t add any essential oils to the container 🙂

    • Can I leave this to sit and not rinse and it still work? I’m thinking of things like light switches and door knobs and toys and such. I have 5 kids and we all have the plague and Itd be amazing if I could just spray it and leave it. We could even make “a game” out of it😂

    Thanks so much for your valuable suggestions for cleaning. I’m 73, and haven’t heard about some of these good ideas. I really enjoy having my little apartment clean and smelling nice! My worst problem is the kitty litter box so I change it often and mix baking soda in it.

  4. I was wondering if spraying Hydrogen peroxide would work to clean a microwave. Thanks for your site; it’s very valuable to me. 🙂

  5. Mira Born says:

    I’ve used hydrogen peroxide in my laundry and around the house for years. Not once have I seen it bleach dark fabric, in fact I’ve used it in the washer with darks without any problems. Can you explain in which situations we should be careful around colored fabric using hydrogen peroxide (e.g. letting it sit beyond a certain amount of time)?

  6. Easiest way to clean a microwave oven is to fill a 2-cup Pyrex measuring cup and microwave for 4-5 minutes. The interior of the microwave will be steamy and moist. Wipe down and perhaps wash the glass plate. Works on even the worst of microwaves although a really nasty one might require a second “steaming”. So simple and quick.

    I have several Reader’s Digest condensed books that are from 1986 + and have been apparently stored in the
    garage or cellar. They look yellowed on the pages. I have read the hydrogen peroxide spray will help but I cannot
    seem to find the formula again on the internet. Please help.

  8. Melissa Lamb says:

    Where did you find a spray nozzle to fit a hydrogen peroxide bottle?

  9. Is it safe to use hydrogen peroxide on granite? I have a problem spots around the faucet where it has turned white probably hard water stain? Any suggestions from you or your readers will be appreciated

  10. I’m SO glad you posted this! I’ve been trying to convert to all natural cleaning products but a lot of times I need whitening action. Now I can get rid of bleach!! Yay!

  11. I read that you can add lemon, lavender, or tea tree oil to hydrogen peroxide for cleaning. I put lemon essential oil in my hydrogen peroxide. Was that wrong?

    • I haven’t tried that but I would just be concerned about the chemical makeup of the hydrogen peroxide long term….Did it work for you?
