How do you get motor oil off of flagstone?

To remove motor oil from flagstone, start by absorbing as much of the oil as possible using paper towels or rags. Then, sprinkle a generous amount of baking soda or cat litter over the stain to absorb the remaining oil, allowing it to sit for several hours or overnight. Afterward, scrub the area with a mixture of warm water and dish soap, using a stiff brush to work the solution into the stone. Rinse thoroughly with water to remove any residue and repeat the process if necessary.
