ABSTRACT:
Removal of soil or stains from carpeting by a dry cleaning process, in which a pad including yarn selected in accordance with the carpet material and an intermediate reduced area of metal foil is rotated in contact with a carpet area moistened with a first cleaning solution including volatile hydrocarbons such as lower petroleum fractions, detergents, a surfactant, and water, over which a second solution of water and hydrogen peroxide is applied. Pad rotation establishes a controlled electrostatic field, and vapor, liquids, soil particles, etc., are drawn into the pad.
