Oil stains are the most common complaint we hear from Houston homeowners. Whether it's a slow leak, a transmission drip, or a spill during an oil change, petroleum stains penetrate deep into concrete pores and won't come out with a garden hose.
Why Oil Stains Are So Stubborn
Motor oil, transmission fluid, and hydraulic fluid are petroleum-based, meaning they bond chemically with concrete. Surface cleaning only removes the top layer, leaving a dark shadow behind.
The Professional Approach
At GreaseKleen, we use a three-step process for oil stain removal:
- Pre-treatment: We apply commercial-grade degreaser directly to the stain and let it dwell for 10–15 minutes to break the chemical bond.
- Hot water extraction: High-temperature pressure washing lifts the dissolved oil out of the concrete pores.
- Surface cleaning: Our rotary surface cleaner provides even, deep cleaning across the entire driveway.
Prevention Tips
After cleaning, consider having your driveway sealed. A quality concrete sealer fills pores and prevents future oil from penetrating. We offer post-wash sealing as an add-on service.
For commercial properties with heavy oil contamination — like parking lots or warehouse floors — we have industrial-strength solutions. Get a free quote today.
