Hydrogen Peroxide Hacks You Wished You Knew Sooner

Sharing is caring!

Alright. I confess. I am that person that has been absolutely clueless about hydrogen peroxide hacks for ages. 

These hacks make my life a lot easier and also allow me to use less harmful chemicals as alternatives. Yep, I’m talking to all you DIYers out there who make your own cleaning products- you’re going to love these ideas. 

However, there are some good reminders we want to keep in mind when using hydrogen peroxide to keep everything safe and kosher. 

Let’s get to that all-important question:

What Should You Not Put Hydrogen Peroxide On?

You should not put hydrogen peroxide on colored fabrics and natural fibers without testing a small area first. You also should not put hydrogen peroxide on marble and granite continually. 


If you’re using hydrogen peroxide to disinfect your marble or granite countertops, you want to use it with caution. Using here and there is ok, but using it continually can actually cause the finish to slowly break down. With continual use, it could also cause some discoloration.

Since hydrogen peroxide is considered an oxygen bleach, A.K.A non-chlorine bleach, it can potentially cause some discoloration in fabrics. So-test, test, test before you directly apply hydrogen peroxide on your clothes/towels/sheets, etc., in that load of laundry.

DO NOT, I repeat, DO NOT mix hydrogen peroxide with vinegar. The combination creates peracetic acid, which can be super harmful to you.

A few notes to consider in regard to your body: You should never ingest hydrogen peroxide, use it as a lightening agent for your hair or skin (without talking to a doctor first, if you so choose), use it in your eyes, or use higher concentrated peroxide without protecting your hands. If you do choose a higher concentration, use gloves to prevent any irritation. 

Ok, so I avoid everything I should, but do I need to rinse off hydrogen peroxide when I use it? Great question.

Do You Need to Rinse Off Hydrogen Peroxide?

In short, yes and no. If there is any potential of ingesting the peroxide somehow, someway, or you are dealing with mold and mildew, you would want to rinse items thoroughly after you use hydrogen peroxide. 

If you are simply cleaning your toilets or mirrors in the bathroom, cleaning and disinfecting doorknobs, toys, the floors, and the like, you do not need to rinse after using hydrogen peroxide.

For example, when it involves some items in the kitchen, like disinfecting dirty sponges, cleaning off fruits and vegetables, cleaning a cutting board etc, or using peroxide to disinfect your toothbrush or retainers, you would want to rinse off the hydrogen peroxide. 

In regard to laundry, use your normal wash cycle to rinse the peroxide off the fabrics. Do not let fabrics sit in hydrogen peroxide for hours or days before rinsing or washing. Leaving peroxide on for an extended period of time can cause discoloration or weakening of the fabric fiber’s strength. 

Unbeknownst to me, there are loads of hydrogen peroxide hacks to use in day-to-day life! I would honestly let that same bottle of hydrogen peroxide sit in the bathroom cabinet for months (even years!) and only take it out when I had a cut or scrape and wanted to give it a good cleaning. 

Let’s take a stroll around the house and find some hacks for that brown bottle tucked away in the back of your bathroom cabinet.

Hydrogen Peroxide Hacks For The Kitchen

Wash Fruits and Vegetables

Fresh produce isn’t always as fresh and clean as we think. With frequent pesticide use nowadays, lots of handling by multiple people on the way to the market or store, and the chance of bacteria on our fruits and veggies, thorough washing before eating is always a good idea. 

There are many options out there, but an easy and non-toxic way of cleaning off all those germs is a 50/50 mix of water and hydrogen peroxide. You can soak, or spray, your produce down with the mixture, let it sit for a few minutes, and then rinse with clean water.

Sanitize Cutting Boards

Plastic and wooden cutting boards come into contact with a multitude of food, and germs for that matter. To keep cutting boards clean and kill off any bacteria that can accrue, pour your 3% hydrogen peroxide directly on the board. Let it sit, and watch it fizz and sanitize! You can use a clean sponge to scrub the hydrogen peroxide all-around your cutting board and then rinse completely.

Disinfect Kitchen Sponges

Speaking of using a sponge, these little absorbent babies can get dirty and grimy pretty fast! Using them to clean dirty dishes, our countertops, our stoves, and our sinks regularly, causes them to also harbour lots of bacteria.

Using equal parts hydrogen peroxide to water in a large bowl, immerse your sponges into the mixture and allow them to sit for a few minutes. You’ll see lots of fizzing. Be sure both sides of your sponge get immersed in the solution. Rinse under clean water. Finally! Odorless and disinfected sponges ready to use.

Clean your Refrigerator

You’ve been there. I’ve been there. Goodness gracious, we’ve all been there! 

We’ve left our food in the fridge a little too long and now those leftovers are starting to smell, the cilantro is wilted and stuck to the produce drawer, and we’ve waited too long to clean that sticky bottle of BBQ sauce which has now made a lovely ring on the bottom of our door organizers. Are we doomed? No way! 

Clean out your fridge as you normally would and use a spray bottle to spray hydrogen peroxide directly to your shelves, drawers, and refrigerator walls. Let it sit for a few minutes to kill any of the bacteria inside and knock out those smelly odors. Wipe down with some water to rinse and let dry. You’ll feel like you’ve never had such a clean fridge!

Hydrogen Peroxide Hacks For Cleaning The Bathroom

Whiten Grout and Get Rid of Soap Scum

The longer we go without cleaning our grout regularly as we should, it seems to turn from a bright white to another far less desirable color, very quickly I might add. Soap scum can also accumulate pretty quickly at the bottom of our showers, tubs, or sinks. Solution? 

To whiten grout and clean soap scum in a non-toxic way, and without the strong chemical smell that makes you dizzy almost immediately, make a paste with about 2 parts baking soda and one part hydrogen peroxide. (If it’s too thick, add a little more hydrogen peroxide. You don’t want it watery, but you also don’t want it clumpy.) Apply the paste on your grout, sinks, and floors of your shower and tub and scrub well with a firm bristled brush. Let sit for at least five minutes and wipe off the paste with a wet rag.

Clean Mold and Mildew

Due to hydrogen peroxide’s antifungal properties, it is a great choice when trying to kill off the spores of any mold and clean away mildew. As I mentioned earlier, peroxide is an oxygen bleach, so it is a nice alternative to the strong chlorine bleach out there. However, this also means it does take a little longer to work, so patience is key here!

Spray hydrogen peroxide considerably onto the mold and mildew and let sit for around 10 minutes or so, once the fizzing stops. Then use a firm bristled brush or rag to deep clean the area and scrub away. Bye-bye fungi!

Streak-free, Shiny Mirrors

Like you would spray a glass cleaner, spray hydrogen peroxide directly on your mirrors or glass you want to spiff up, and use a lint-free cloth to buff. Beautiful streak-free mirrors in minutes, without too much elbow work!

How To Use Hydrogen Peroxide In Your Laundry

Remove Tough Stains and Blood Stains

Whether it’s berry stains, grass stains, blood stains, etc., apply a paste of baking soda and hydrogen peroxide then scrub with a brush to lift the stain. A toothbrush is helpful here. Also, allow the mixture to sit for a few minutes then wash as normal.

This has been my lifesaver!

Be sure to check your laundry before you put them in the dryer to make sure the stains are removed. This is because the heat from the laundry dryer can cause them to set, and once that happens, it’s extremely difficult to get them out. If the stain remains, use some more hydrogen peroxide and baking soda paste and scrub, scrub, scrub. Remember to rewash or at least rinse.

Although this can help to get some stains out after they have been left for a while, immediate action after a stain is always best and most effective!

NOTE: As mentioned above, before you test this method on any whites and colored fabrics, do a test area to make sure it does not cause any discoloration before you use hydrogen peroxide on any large stains.
