Remove oil stains from asphalt concrete by first applying an absorbent material and allowing it to soak up the fluid. Then sweep up the debris and scrub the driveway using baking soda and water. Apply heavy-duty laundry detergent to any remaining traces of oil and scrub again.Continue Reading
Begin removing the stain as soon as you can so it does not have a chance to soak into the surface. Use kitty litter, corn meal, sand or cornstarch to absorb the oil by spreading the material on top of the oil and allowing it to absorb the fluid.
Use a stiff broom and dustpan or flat-edge spade to sweep up the absorbent material.
Apply a layer of baking soda and water to the oil stain. Use a stiff brush to scrub the area before using a garden hose to rinse away the baking soda.
If traces of the stain remain, cover it with heavy-duty laundry detergent and use a scrub brush to scrub the area. Scrub alternately with baking soda and laundry detergent until you remove the stain, then rinse the area with water.
If the stain remains after scrubbing, apply a product specifically designed for cleaning asphalt, and follow the manufacturer's directions for removing oil.
