Why oil stains are stubborn
Concrete is porous. Oil soaks in, and the longer it sits, the deeper it goes. Water alone can’t lift it.
For fresh spills
- Cover the spill with cat litter or sawdust right away to soak up as much as possible.
- Sweep it up after a few hours.
- Scrub the spot with a degreaser and a stiff brush, then rinse.
For older stains
Older stains need a stronger degreaser left to sit, then hot water and a surface cleaner. Our garage and driveway pressure cleaning uses this approach.
Setting expectations
Most stains fade a lot. Very old stains that have soaked deep into the concrete may leave a light shadow.
Keep stains from coming back
- Fix the leak at the source.
- Use a drip mat where you park.
- Seal the driveway so future spills sit on top and wipe up more easily.
