Test Driveway Oil Stain Removal Method First
The Poultice Process A poultice is essentially a targeted mask that pulls deep-seated oil to the surface. Use a stiff-bristled broom or a scrub brush to agitate the dried paste, loosening any particles that are stuck to the surface.
The age of the stain also dictates the method; a fresh spill is reactive, while a decades-old stain is often about oxidation and requires a more aggressive strategy. You must allow sufficient time for the chemical reaction to occur—usually between 24 and 48 hours.
