Scrubbing Technique The effectiveness of the cleaning agent is largely dependent on the mechanical action applied. Mechanical Action and Degreasing Agents Once the surface is prepped, the removal process relies on breaking the bond between the oil and the cement.

This ensures that the cleaning solution can make direct contact with the stained concrete rather than being diluted or obstructed by surface grime. 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.
Whether the mark comes from a leaking vehicle, a spilled cooking fat, or a workplace spill, the porous nature of cement acts like a sponge, drawing the oil deep into the surface. If the stain persists, repeating the process is often necessary.

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. Unlike water-based spills, oil is hydrophobic, meaning it repels moisture and does not dissolve easily.
