Abstract: The present invention is a powdered stain remover formulation which when mixed with water exhibits bleaching and stain discoloration properties together with the required detergency, and also exhibits mildewcide and bacteriocidal properties. The formulation includes calcium hypochlorite; a surfactant to promote detergency by emulsification, such as sodium dodecylbenzene sulfonate and a polyacrylic acid salt, such as sodium polyacrylate, to further promote cleaning by chelation. The stain remover formulation is applied to the stained surface by spraying, rolling or brushing. In this manner, water stains, tobacco, soot, mold, mildew and other stains are readily removed from the desired surface, such as sprayed textured walls and ceilings, tiles, masonry, fiberglass and plastic furniture.
