Oil stains on concrete driveways are the #1 reason San Diego homeowners call us. Most have tried multiple at-home approaches that didn't work. Here's why and what does.
What doesn't work
Kitty litter: absorbs surface oil. Doesn't touch the oil that's already penetrated the concrete.
Cola or vinegar: not enough surfactant to dissolve oil. Cosmetic improvement only.
Dish soap + scrubbing: works for fresh stains but old stains are too deep.
What works
Hot water (180°+) + commercial degreaser pressure washing. Hot water dissolves penetrated oil and degreaser separates it from concrete. Then pressure rinse removes everything.
For severe stains: poultice treatment first (24-48 hour cleaning agent paste). Then hot pressure wash.
What pros use
Truck-mounted hot water systems heating to 200°F. Commercial-grade degreaser. 3,500-4,000 PSI pressure. Hand-detail on stubborn spots.
The result
Most oil stains 80-95% gone after one treatment. Old stains may need a second pass or a poultice treatment first. Concrete back to original color.
Cost reality
Single driveway with oil stains: $185-345 depending on severity. Cheaper than replacing concrete sections ($4-8/sqft).
The right tools fix in 90 minutes what home methods can't fix in 30 hours.
