How to Remove Oil Stain From Asphalt

Asphalt driveways and parking lots are prone to oil stains due to vehicle leaks and spills. These stains not only look unsightly but can also deteriorate the asphalt surface if left unattended. Fortunately, there are several effective methods to remove oil stains from asphalt. Here are some step-by-step instructions to help you get rid of those stubborn oil stains.

1. Absorb the fresh oil: If the spill is recent, sprinkle a generous amount of cat litter or sawdust over the stain. Allow it to sit for a few hours or overnight, and then sweep it away.

2. Pre-treat the stain: Apply a commercial degreaser or dish soap to the stain and scrub it using a stiff brush or broom. Let it sit for 10-15 minutes to penetrate the oil.

3. Hot water and detergent: Boil a large pot of water and add a few tablespoons of laundry detergent or dish soap. Pour the mixture directly onto the stain and scrub vigorously with a brush.

4. Pressure wash: If the stain persists, rent a pressure washer with a nozzle specifically designed for removing oil stains. Direct the water stream onto the stain, maintaining a distance of about 12 inches to avoid damaging the asphalt.

5. Apply a degreaser: For stubborn stains, apply a commercial degreaser specifically designed for asphalt surfaces. Follow the manufacturer’s instructions and rinse thoroughly after use.

6. Baking soda and hydrogen peroxide: Create a paste using baking soda and hydrogen peroxide. Apply it to the stain and scrub gently with a brush. Rinse off with water after a few minutes.
