The secret to oil stain removal for asphalt is using the right method, not the most pressure. In Wisconsin, we match the cleaner and pressure to the surface so it comes out clean without damage. For asphalt, that means low-to-moderate pressure wash.
Method and pressure
Cleaning solution: An asphalt-safe degreaser; avoid solvent-based products.
Cleaning asphalt safely
Asphalt is softer than concrete and is held together by its binder, so it is washed at lower pressure. Washing removes dirt and some oil staining before sealcoating, but old, absorbed oil stains rarely disappear completely.
Avoid: High pressure and harsh solvents that loosen the aggregate and break down the binder.
How often: Before sealcoating, typically every 2-3 years.

Do you use high pressure for oil stain removal for asphalt?
For asphalt: usually 1,500-2,500 PSI; hot water helps with oil. What we avoid: high pressure and harsh solvents that loosen the aggregate and break down the binder. The cleaning solution does most of the work, followed by a gentle rinse.
Is oil stain removal for asphalt safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule oil stain removal for asphalt?
Before sealcoating, typically every 2-3 years. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do, and sealers and stains need dry weather to cure. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
