The OxiClean formula is a combination of ingredients, the chief ingredient being hydrogen peroxide. Another essential part of the formula is the surfactants, or detergents. Combined, these ingredients work together to do some amazing things. OxiClean uses an oxidating technology that allows you to use it on coloured fabrics and carpets, unlike chlorine-based bleaches which can permanently damage coloured fabric. OxiClean seeks out the stain’s surface and lifts the stain away; not the colour.
