Nudoo is a USDA authorized upholstery and carpet shampoo. Concentrated. Fortified with brighteners, detergents, foaming agents, solvents and penetrates. Upon dilution with water and applied by hand or through machines, a rich dry foam is produced which lifts and brings soils to surface where they are carried away by machine or vacuum. Dries to a non-tacky residue. Prevents resoiling of carpet.
