Abstract
A workpiece cleaning element incorporates an injection molded resin core having integral spacers formed at a central portion of the resin core. The resin core is formed from a suitable material that does not leech chemicals or become brittle in the presence of cleaning fluids. A substantially resilient cleaning material located on the resin core includes a plurality of raised ribs that perform contact scrubbing of the workpiece. Each rib includes a longitudinal channel formed therein that divides the rib into a leading cleaner surface and a trailing cleaner surface. The ribs are arranged on the cleaning element in a pattern that promotes effective removal of debris from an inner position on the workpiece to the outer edge of the workpiece.
