17 Uses for Hydrogen Peroxide You Never Knew About

Keep a bottle in every room of your house to whiten teeth, clean mirrors, prevent stains, and more.

Use hydrogen peroxide as a mouth rinse


Some uses for hydrogen peroxide aren't intuitive, but they still work! Save money on mouthwash by mixing equal parts hydrogen peroxide and water and swish it around your mouth. Bonus: It’ll help naturally whiten your teeth in the process. Check out these other easy ways to whiten your teeth naturally at home.

Disinfect toothbrushes and dental appliances


Dental hygiene is one of the most effective uses for hydrogen peroxide. Though toothbrushes should be replaced every three months or after you have a cold—not doing so is one of the top tooth-brushing mistakes—you may not always have time to run to the drugstore to buy a new one. In the meantime, soak your toothbrush in hydrogen peroxide to kill the germs. It works for retainers and mouth guards, too.

Clean your fruit and veggies


If you’re looking for an alternative to expensive fruit and vegetable washes, spritz a little food-grade hydrogen peroxide on them instead to help clean bacteria away. Rinse thoroughly before consuming. When you're finished, use these tricks to keep fruit and veggies fresh longer.

Clean your grubby sponges


Have some funky sponges in the kitchen or bathroom? The many uses for hydrogen peroxide can also help you get rid of their dirty appearance and weird smell. Soak sponges in equal parts hydrogen peroxide and water, then rinse thoroughly. If that doesn't work, it's time to toss it. After all, it is one of the 9 everyday items dirtier than a toilet seat.

Get out that stubborn bloodstain


Most uses for hydrogen peroxide involve brightening or bleaching an object, which makes sense, because the chemical compound is a kind of bleach. That means it'll do wonders on stained white fabrics. Pour some directly onto a stain and let it sit, then blot it out and rinse it in cold water. You can also use these common items that remove blood stains if you don't have any hydrogen peroxide on hand.

Spritz hydrogen peroxide in an empty dishwasher or cleaned-out fridge. After letting it sit for a while, you’ll be able to wipe the mess cleanly away. Follow these 9 steps to give your fridge the most thorough cleaning.

Get softer, cleaner feet

Clean musty towels


As many uses as there are for hydrogen peroxide, there are even more household uses for vinegar. So combining them gives you the ultimate clean.

Don’t worry, the vinegar smell won’t linger.

Whiten your clothes without bleach


Just like with the bloodstains, hydrogen peroxide can be used as a general bleach for whites in your wash. Instead of bleach, add half a cup to your wash cycle. Did you know these eight weird things can also remove stains?
