What to know about cleaning asphalt
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.
