Hydrogen Peroxide Cleaning Uses (and Safety Tips)

Hydrogen peroxide (the 3% solution sold in brown bottles) is a useful household cleaner. It breaks down into water and oxygen, and it has a mild bleaching effect, which makes it great for whitening and stain removal.

How to Use It Safely

• Keep it in its original brown bottle. Light breaks it down and makes it less effective.
• You can screw a spray nozzle directly onto the bottle.
• Never mix it with vinegar in the same container, which forms a corrosive acid.
• Never mix it with bleach.
• Test on fabrics and colored surfaces first, since it can lighten colors.
• Wear gloves if you have sensitive skin.
