Hydrogen peroxide is a chemical compound that acts as a powerful disinfectant and is commonly used for cleaning and sterilizing surfaces and medical instruments. It is effective against a wide range of bacteria, viruses, fungi, and other microorganisms. Hydrogen peroxide works by breaking down into water and oxygen, leaving no harmful residue behind. It is also a bleaching agent and can be used to remove stains from clothing and surfaces. Hydrogen peroxide is widely available in different concentrations and can be used for various purposes, such as wound cleaning, mouthwash, and hair bleaching. However, it should be used with caution and proper protective equipment, as high concentrations can cause skin and eye irritation.
