What is Oxygen Bleach? 1  Oxygen bleach is the common term for sodium percarbonate, a compound of natural soda crystals and hydrogen peroxide.  Oxygen bleach is widely available in detergents and other cleaning products and comes in a solid, powder-like form, usually diluted in water before use.
Oxygen bleach is marketed in both liquid and powder forms, but for the sake of grout cleaning, you will want to use the powder form because the liquid typically comes in small spray bottles and doesn't give you the amount of product that you need to completely saturate a large area of grout.
