    Abstract: A process of cleaning fibrous materials such as carpets and the like by applying an aqueous composition which forms a foam on the material and then dries to a powder which can be brushed off or vacuumed away. The aqueous composition is an aqueous dilution of a mixture consisting essentially of (a) an alkali sulfate derived from an ethoxylated or polyethoxylated alcohol, (b) an alkali salt of a sulfosuccinic acid half ester, and (c) water. Of the solids content the ethoxysulfate salt comprises about 20 to 50 percent by weight and the sulfosuccinate salt about 50 to 80 percent by weight. Up to about half of the content of the ethoxysulfate salt may be replaced by an equivalent amount of alkali lauryl sulfate.
