This is constructed with an 80/20 microfiber yarn blend and looped-pile polypropylene scrubbing strips for aggressive abrasive action. The balanced weave allows for soil to be loosened by the scrub strips and picked up by the microfiber yarns. The center construction eliminates the traditional foam and adds a layer of absorbent microfiber fabric for better absorbency and slower release. These pads are industrial quality and withstand hundreds of launderings.
