Solid-A-Sorb is a fine granule, 100% Diatomaceous Earth premium all-purpose absorbent. A bit more coarse than sand, the additional surface space allows it to quickly clean up water, oil and grease and provide gritty traction for slick surfaces. Create a clean and safe environment in garages, warehouses, workshops and machine shops. Absorbs oils, coolants, solvents and water-based fluid.
