These sponges feature a medium-duty scouring pad on one side and a cellulose sponge on the other side. The cellulose sponge absorbs water while the green abrasive pad powers off stuck on food, residue and stains away from surfaces. Use with plain water or neutral pH detergent. Sponge works well on sinks, countertops, tables, walls, pots and pans and rinses clean easily. Bulk packaged 40 sponges per case.
