ABSTRACT:
A dry-type carpet cleaning composition is disclosed which comprises shreds of a hydrophilic polyurethane foam which incorporates abrasive particles surfactants, and adjuvants such as fragrance, solvents, anti-static agents and fiber emollients. The foam shreds are effective to clean both wet and dry carpeting since they are highly water-absorbent and can be readily removed from the carpet surface when wet.
