Made for heavy-duty cleaning, these extra-large commercial sponges are super absorbent for large spills and long-lasting. These cellulose sponges are 10 times more absorbent than polyurethane sponges. Stronger material means they are less likely to fall apart. Professional-grade, nonscratch sponges clean tough, baked-on messes 50 percent faster than other products. They are great for use in the kitchen, garage and outdoors to clean cast-iron pots, stove burners, broilers, garden tools, grills and more.
