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.

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.

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.

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.

Count this as one of the best tricks to get healthy and gorgeous nails. Take one part hydrogen peroxide to two parts baking soda to form a paste, and gently massage the paste over your nail beds. Let it sit for two to three minutes then rinse away the dingy yellowness.

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. Instead of tossing musty, old towels, add a half a cup of hydrogen peroxide and half a cup of vinegar to your wash cycle as a pre-soak, then wash as normal. Don’t worry, the vinegar smell won’t linger.
