Abstract: A portable apparatus for cleaning articles comprises a flexible waterproof pouch with a flexible absorbent lining and a watertight closure. A workpiece article to be cleaned is inserted into the pouch. External manipulation of the pouch causes the lining to abrade the workpiece, thus cleaning it. Soap solution, detergent solution, or cleaning fluid poured onto and absorbed by the absorbent lining enhances cleaning. The absorbent lining may have an abrasive surface which further enhances cleaning. The apparatus when not in use is flat and flexible and may be conveniently carried in a user's pocket. The watertight closure prevents escape of the liquid absorbed in the absorbent lining onto the user's clothing or person.
