Spread this paste generously on the stain, making sure to extend a bit beyond its border. Cover the poultice with plastic wrap and let it sit for 24 hours.cetone may work if the stain is close to the surface. However, if the oil has absorbed deeper into the stone you need to try a poultice that will draw the oil out. It may take repeated applications and may not remove it all.
