Just about every car owner has faced those dark patches that appear under parked vehicles. While these marks might look permanent, there are simple ways to get rid of them.
According to Bob Vila, a home improvement expert and TV host, "Oil stains not only look bad, but they can actually damage concrete over time by working their way deep into the surface." His advice appears in a detailed article about concrete maintenance on BobVila.com.

Our goal is to help you tackle this common problem effectively, whether you're dealing with a fresh spill or an old, stubborn stain that's been there for months.
Things to Do When Cleaning Oil off Concrete
Cleaning oil off concrete requires a systematic approach to effectively remove both fresh spills and set-in stains. The process involves multiple steps that work together to break down and lift the oil from the porous concrete surface, preventing long-term damage and unsightly marks.
Using the right combination of absorbent materials, cleaning solutions, and proper techniques is crucial for achieving the best results.
- Apply absorbent material (kitty litter, baking soda, cornstarch) immediately to soak up excess oil
- Allow absorbent to sit for several hours to draw out as much oil as possible
- Remove and dispose of the oil-soaked absorbent material properly
- Scrub the area vigorously with a stiff brush to loosen embedded oil
- Apply degreaser or soap solution and let it penetrate for 15-20 minutes
- Work the cleaning solution into the concrete with brush in circular motions
- Rinse thoroughly with pressure washer or garden hose
- Create a poultice for stubborn stains and apply overnight
- Repeat process as needed until stain is completely removed
- Verify final rinse removes all cleaning residues
Things to Avoid When Cleaning Oil off Concrete
When cleaning oil stains from concrete, it's essential to understand that using the wrong cleaning methods or materials can worsen the situation or cause permanent damage to the surface.
Improper cleaning techniques not only risk damaging the concrete but can also make future cleaning efforts more challenging and potentially create safety hazards.
- Muriatic acid – Highly corrosive substance that etches concrete surfaces, leading to permanent damage and difficulties with future cleaning.
- Excessive bleach application – Creates uneven discoloration and can weaken the concrete's surface integrity over time.
- General-purpose cleaners – Ineffective for oil removal and waste time and resources with multiple applications.
- Manual scrubbing without proper solutions – Results in unnecessary physical effort with minimal impact on stubborn oil stains.
- Untested chemicals – Risk of unexpected reactions that could damage concrete or create hazardous conditions.
- Hot water pressure washing alone – Can drive oil deeper into the concrete's porous surface.
- Wire brushes – May scratch and damage the concrete's surface, creating rough patches.
- Painting over oil stains – Prevents proper adhesion and leads to peeling or flaking of the paint.
Steps
Cleaning oil stains from concrete requires a methodical approach that combines absorption techniques with thorough cleaning solutions.
The process involves first removing excess oil through absorption, followed by deep cleaning with appropriate solutions and tools, ensuring the concrete surface returns to its original state without causing environmental harm or damaging the surface itself.
Step 1: Cover the oil stain completely with an absorbent material like kitty litter, baking soda, or cornstarch.
Step 2: Allow the absorbent material to sit for 6-8 hours to soak up the oil.
Step 3: Sweep away the used absorbent material and dispose of it properly.
Step 4: Scrub the stained area with a stiff-bristle brush.
Step 5: Mix hot water with degreaser or dish soap.
Step 6: Apply the cleaning solution to the stain and let it sit for 15-20 minutes.
Step 7: Scrub the area again with the brush and cleaning solution.
Step 8: Rinse thoroughly with a pressure washer or garden hose.
Step 9: Repeat the process if necessary.
Step 10: For stubborn stains, apply a commercial concrete oil stain remover according to product instructions.
