This Oil-Thirsty Absorbent soaks up the messiest spills fast. Greasweep is made of 100% natural plant-based ingredients and absorbs 35 times faster than clay adsorbents on the market today. Greasweep allows you to save money by using less product on the same spills. Cleaning up Greasweep is as easy as pushing a broom. And because Greasweep is capable of absorbing up to three times its weight in oil, it can be reused over and over until completely saturated. And to top it off, Greasweep leaves no residues. Just sprinkle it on the spill, mix it in, sweep it up and dispose. Greasweep is made of a rice hull that is reduced to the simplest ash form (little or no carbon). These rice hulls are mostly silica and cellulose. The burning process consumes the cellulose and leaves the skeleton of silica. This skeleton resembles a bundle of drinking straws which are used to suck up any liquids, especially oils. Greasweep outperforms Kitty Litter, Clay, Wood Fibers, Fly Ash and many more.
