Prosoco Stand Off® Oil and Grease Stain Remover is a poultice cleaner for removing stubborn oil and grease stains out of pavers, concrete, stone and other porous surfaces. It's easy to use. Just pour the Stand Off Oil & Grease Stain Remover on the embedded stain. This product spreads out to make an instant poultice with no mixing, troweling, plastic covering or tape needed. As the poultice dries, the Stand Off pulls the contaminants out of the substrate, capturing them in its highly absorbent blend of batter-thick surfactants, solvents and powders. After about 5–8 hours, simply sweep up the dried poultice and its absorbed contaminants for easy disposal.
