Edgewater Industries’ Pour-N-Restore Oil Stain Remover lifts and absorbs embedded oil stains as it dries from a liquid to a powder. This is made possible by combining a powerful citrus degreaser with a non-leaching absorbent, says the company. To use, just apply the product, let it dry and sweep it up. No scrubbing or rinsing is required. The product is biodegradable, and phosphate-free.
