Oil Eater Naturals range in size from 16 x 18 in. to 28 in. x 150 ft rolls. Pads are made of natural plant by-products that feature woven construction. Oil-only pads and rolls soak up oil and repel water; universal pads and rolls soak up oil, water and other liquids; and absorbent socks control larger spills and protect drains. Pads will absorb up to 20% more than melt blown polypropylene pads.
