Abstract
A dry-type textile cleaning article is disclosed which comprises a friable hydrophilic polyurethane foam body which incorporates abrasive particles, solvents, surfactants, and adjuvants such as fragrance, biocides, and fiber emollients. When rubbed over a textile surface the foam body yields shreds which are effective to remove both liquid and dry soils from textiles.
