Gas Stains on Asphalt Can Be Removed

Gas stains on asphalt are unsightly but often removable. Immediate action is best. Absorb excess liquid, then use a degreaser, dish soap, or baking soda paste. Scrub vigorously with a stiff brush and rinse thoroughly. Repeat if necessary. Prevention is key - address leaks promptly.

Understanding the Stain

• Gasoline dissolves the asphalt binder, causing discoloration.
• The longer the gas sits, the deeper the stain penetrates.
• Fresh stains are easier to remove than old, set-in stains.

Removal Methods

1. Absorb Excess: Immediately soak up as much gasoline as possible with absorbent materials like kitty litter, sawdust, or paper towels.
2. Degreaser Application: Apply a concrete/asphalt degreaser according to the product instructions. Let it sit for the recommended time.
3. Scrubbing: Use a stiff-bristled brush to scrub the stained area vigorously.
4. Rinsing: Rinse thoroughly with water. A pressure washer can be helpful, but use caution to avoid damaging the asphalt.
5. Repeat: Repeat the process if the stain persists.

Alternative Cleaning Agents

• Dish Soap: Mix dish soap with water and scrub. Effective for lighter stains.
• Baking Soda Paste: Create a paste with baking soda and water. Apply, let sit, scrub, and rinse.
