Looking for driveway cleaning for asphalt in Maine? We look at the surface first, choose the right method and pressure for it, and give you a price before any work starts. With asphalt, the right approach is 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.
