How to Remove Oil Stains From a Driveway Before Sealing

Why oil stains matter

Sealer needs a clean, dry surface to bond. Oil and gasoline stains repel asphalt-based sealcoat and cause fish-eyes, peeling, and bald spots in the finish.

DIY removal — what works

1. Cat litter or absorbent powder — covers fresh stains, soaks up oil
2. Degreaser + stiff brush — for set-in stains, scrub with hot water
3. Dish soap + baking soda paste — light surface stains
4. Pressure wash — finishes the prep, removes residue

What we do on Barrie sealing jobs

Stains and damaged areas are reviewed for product compatibility. Specialized degreasing, primers or patching must be identified in the approved scope; they are not automatic additions to the standard six-step sealing service.

When stains can't be removed

Deep, soaked-in oil patches sometimes need a primer coat or even spot patching before sealcoat. We'll point these out during the quote.

Bottom line

Don't worry if your driveway has oil stains — most can be cleaned and sealed over. Our standard preparation is described in the residential service details; any specialized stain treatment or repair is confirmed separately in your written quote.
