TC Hydrogen Peroxide 3% is a diluted hydrogen peroxide solution commonly kept in households and first-aid kits. At three percent concentration, it is often used to help clean minor wounds, remove surface stains, and sanitize small household surfaces. Apply as directed on the packaging, and avoid contact with eyes or ingestion. Store in a cool, dark place in its original sealed bottle to maintain stability. Keep out of reach of children and consult product labeling for specific usage instructions, precautions, and disposal recommendations.
