Hydrogen Peroxide Hacks You’ll Wish You Had Known Sooner

Most people know hydrogen peroxide as the stinging, bubbling liquid your parents forced on your cuts when you were younger. Hydrogen peroxide is the chemical compound H202, which acts as a bleaching agent, antibacterial, and antiseptic.

Since hydrogen peroxide is relatively safe, you can use it to whiten your teeth, clean your ears, and care for your skin. You can clean your entire house with hydrogen peroxide alone–if you know how to use it correctly. Here are the best hydrogen peroxide hacks that’ll make your life ten times easier.

According to a 2004 study in the Journal of Dentistry, hydrogen peroxide effectively bleaches teeth. To whiten your teeth, create a solution of 1/2 water and 1/2 hydrogen peroxide. Swish it around in your mouth for at least 30 seconds, or as long as you can stand. Spit the solution out if it hurts your mouth, and don’t swallow it.

The higher the concentration, the brighter the whitening. However, a 2006 study from the same journal reported that higher concentrations could harm the enamel. If you use a higher concentration (25% or 35%), shorten the amount of time that the peroxide is in your mouth.
