Hydrogen peroxide is one of those household staples most people keep tucked away in their medicine cabinet — usually only brought out for treating cuts or scrapes. But here’s the secret: hydrogen peroxide is so much more than just an antiseptic .
This inexpensive, non-toxic disinfectant has a surprising number of cleaning, beauty, and health uses that can simplify your daily routine and help you maintain a cleaner, healthier home.
In this article, we’re sharing 16 unexpected yet practical ways to use hydrogen peroxide around the house — from removing stains and killing mold to whitening teeth and boosting laundry freshness.
Let’s dive in!
π§Ό What Is Hydrogen Peroxide?
Hydrogen peroxide (H₂O₂) is a mild antiseptic commonly used to prevent infection in minor cuts, burns, and scrapes. It works by releasing oxygen when it comes into contact with damaged tissue, creating an environment where bacteria can't survive.
While the 3% solution sold in stores is safe for everyday use, always remember:
- Don’t ingest it.
- Avoid using it on deep wounds without consulting a doctor.
- Store it in a cool, dark place — it breaks down when exposed to light.
Now let’s explore all the clever ways you can put this multipurpose liquid to work!
