Affresh Washer Cleaning Kit contains 3 Power Puck tablets and 4 Grit Grabber cloths. The tablets remove and prevent odor-causing residue that can occur in all brands of HE washers. Affresh cleaner is a formulated, slow-dissolve, foaming tablet that gets under residue, breaks it up, and washes it away leaving the washer smelling fresh and clean. Simply place one tablet in the wash basket (without clothes) and run a Normal Cycle (hot option) or Clean Washer Cycle. The Grit Grabber premoistened cloths have been formulated to penetrate, dissolve and remove odor-causing residue from the rubber door seal. Now consumers can clean where they can't reach with the Power Puck tablets and where they can with the Grit Grabber cloth.
