Tough, durable, and economical: Eight layers of 100% polypropylene are thermally bonded to be so durable they won't rip, tear, or fray even when saturated. Fast absorbing: Unique dimple pattern speeds up the wicking of oil throughout the mat for faster, easier cleanup. Cleanly absorbs oil: Highly absorbent, fine-fiber construction won't leave behind liquids or fiber residue. These oil absorbing mats are convenient for any kind of oily mess big or small, and are sure to be a staple in your shop or garage. Perfect for outdoor and marine applications. Clean spills on water: Oil absorbing mats float on water; absorbing only the oil and wicking away the water.
