The Best Techniques for Removing Oil Stains from Concrete

Published: April 14, 2025

Oil stains on concrete driveways, garages, or patios are not just unsightly—they can also become a slippery hazard and make future resurfacing projects more difficult. Fortunately, with the right materials and methods, most oil stains can be successfully removed.

In this guide, we’ll walk you through the best techniques for removing oil stains from concrete surfaces and restoring your space to a clean, professional look.

1. Act Fast: Fresh Oil Stains

The sooner you address the spill, the better your chances of fully removing the stain. Use the following steps immediately after a spill:

Step 1: Blot up excess oil with paper towels or an absorbent cloth. Do not wipe—it spreads the oil.

Step 2: Cover the area with absorbent material like kitty litter, sawdust, or baking soda. Let it sit for several hours or overnight.

Step 3: Sweep it up and dispose of it properly.

Follow up with a degreaser or detergent to scrub away any residue.

2. Use a Commercial Concrete Degreaser

For older or set-in stains, a concrete-specific degreaser is often the most effective solution. These products are designed to break down petroleum-based contaminants and pull them from the porous concrete surface.

  • Apply the degreaser as directed
  • Scrub with a stiff-bristled brush
  • Rinse thoroughly with a pressure washer or hose

Repeat if necessary.

3. Try a Homemade Solution

For mild stains or eco-conscious cleaning, try a DIY paste made from:

  • Baking soda or cornstarch
  • A few drops of dish soap
  • Warm water to form a thick paste

Apply the paste, let it sit for 30–60 minutes, then scrub and rinse.

4. Poultice Method for Deep Stains

For deeply embedded oil spots, use a poultice—a thick paste that draws oil out of the concrete as it dries.

  • Mix an absorbent material (like diatomaceous earth) with a solvent such as acetone or commercial degreaser
  • Apply to the stain and cover with plastic wrap
  • Let it sit for 24 hours, then scrape off and rinse

This is ideal for garage floors or commercial spaces with heavy staining.

5. Pressure Washing for Large Areas

For wide or heavily stained surfaces, pressure washing is often the fastest solution. Use a degreaser beforehand for better results, and ensure you’re using the appropriate pressure setting to avoid damaging the concrete.

Preventing Future Stains

  • Apply a concrete sealer to create a stain-resistant surface
  • Place drip trays under vehicles
  • Clean spills as soon as they occur
