For more severe cases, commercial concrete degreasers provide a stronger alkaline solution that accelerates this emulsification process, making the oil easier to rinse away. Blotting the area with an absorbent material—such as cat litter, sawdust, or paper towels—can pull a significant amount of the oil out of the cement before it sets.
Dry Methods to Remove Oil from Cement
Unlike water-based spills, oil is hydrophobic, meaning it repels moisture and does not dissolve easily. When applied directly to the stain and scrubbed with a stiff-bristled brush, the surfactants in the soap work to emulsify the oil, lifting it from the porous surface.
For vertical surfaces or areas where standing oil is present, allowing the solution to dwell for 10 to 15 minutes before scrubbing can significantly improve results. For porous or colored concrete, be mindful that the high pressure or harsh chemicals may alter the surface texture or appearance slightly, so a test patch in an inconspicuous area is always recommended.

It is important to work the solution into the stain rather than just spreading it around the perimeter. Using a stiff-bristled push broom or a dedicated concrete brush, agitate the solution vigorously.
