Hydrogen peroxide releases oxygen on contact with tissue, which produces the familiar fizzing. That action loosens debris and kills some germs, and it is what makes it useful for cleaning and for softening ear wax.

What Hydrogen Peroxide Is Used For

Cleaning minor wounds and grazes of dirt and debris
Softening ear wax, as a diluted ear drop
Mouth rinse for gum inflammation and mouth ulcers, well diluted
Disinfecting surfaces and equipment

Common Side Effects

Stinging and temporary whitening of the skin
Irritation of the gums with repeated use
Dryness or itching of the ear canal

Precautions

Only the dilute strengths sold for medical use are appropriate on the body. Higher concentrations cause burns and must never be swallowed or put in the eye. It is no longer recommended for repeated wound cleaning, since it damages healing tissue along with the germs, and clean water is usually better. Do not use ear drops if the eardrum may be perforated or if there is ear discharge or pain.
