The Sellars Absorbent Materials EverSoak Light-Duty Absorbent Pads, No. 22883, are designed to soak up both oil and water as well as grease, transmission fluid, coolants, diesel fuel, and many other fluids. They are made with 70 percent recycled cellulose fibers and are Class A fire retardant when pad is dry. With coverstock only on the top side of the sorbent pad, the pad instantly begins to soak up liquid, keeping the pad firmly in one place while still maintaining its durability. They are made in the U.S.A. and not intended for use with aggressive acids or caustics.
