How do you wash gasoline off vinyl siding?

To wash gasoline off vinyl siding, first ensure the area is well-ventilated and avoid open flames. Mix a solution of warm water and dish soap, then apply it to the affected area using a soft cloth or sponge. Rinse thoroughly with water to remove any residue. If stains persist, a mixture of vinegar and water may help, but always test in an inconspicuous spot first.
