Bleach refers to a chemical substance used primarily as a cleaning agent or disinfectant. It is a strong oxidizing agent and is commonly used to remove stains, whiten fabrics, and disinfect surfaces. The most common type of bleach used in households is sodium hypochlorite, which is a solution of chlorine in sodium hydroxide.

Bleach is effective in killing bacteria, viruses, and other microorganisms, making it a powerful disinfectant for cleaning and sanitizing purposes. It is commonly used to clean and sanitize bathrooms, kitchens, floors, and other surfaces. In laundry, bleach can be used to remove tough stains and to whiten white fabrics.

However, it is essential to use bleach with caution, as it can be harmful if ingested or if it comes into contact with the skin or eyes. It should always be used according to the manufacturer’s instructions and should be kept out of reach of children. Additionally, bleach should never be mixed with other cleaning products, especially ammonia or products containing ammonia, as this can create toxic fumes.
