Grease Beast scrub pads are specially designed to clean up dirty, greasy surfaces fast and safely. The Grease Beast scrub pad foam material was originally designed to clean up the oil spill in the Gulf of Mexico. The innovative heavy-duty scrub pads are oleophilic and absorb grease, grime, dirt and oil like a magnet. They suck the mess right up. The hydrophobic properties of the pads mean that they don't retain water, which therefore inhibits the growth of bacteria and mold. Our scrub pads are the first ever cleaning pad that will never smell bad and are Ideal for various cleaning tasks around the house. 40x more durable than the competition, completely safe to use and environmentally friendly. Scrub pads are plant-based and made from renewable resources. They contain no petroleum by-products, adhesives, glues, chemicals or other harmful materials. The no scratch scrubber side is made from natural walnut shells.
