Sifter Parts & Service provides FDA-approved polyurethane screen cleaning balls and cubes to prevent sifter screens from clogging with product. Polyurethane balls are more abrasion resistant than screen cleaners made of other materials and provide a longer service life. Unlike rubber or neoprene, the polyballs are non-porous and oil, moisture and chemical resistant.
