Gunk and grime are no match for this open-celled synthetic sponge with aluminum oxide scouring surface that's ideal for pots, pans, and utensils. Great for heavy-duty and general cleaning, the green abrasive surface is permanently bonded to one face of the sponge, while the other face is a soft, absorbent, flexible, synthetic material. Not recommended for glass, plastic, or coated surfaces such as enamel or ceramic pots and pans.
