Work the bristles in a circular motion to agitate the oil and lift it from the cement pores. Oil is hydrophobic, meaning it repels water and sinks deep into the tiny pores and capillaries of the cement surface.
Why Rubbing Worsens Oil Stains on Concrete Surfaces
Over time, the oil oxidizes and binds with the minerals in the concrete, often trapping dirt and dust that further darken the area. Apply the soapy solution directly to the stained area and use a stiff-bristled brush to scrub the spot.
Rinse thoroughly with clean water and repeat the process if necessary. Avoid rubbing the stain, as this spreads the oil over a wider area and grinds it into the surface.
Why Avoiding Rubbing is Crucial for Concrete Oil Stain Removal
Because TSP can be harsh on the environment, many modern alternatives offer similar power with a reduced ecological footprint. The chemical reaction breaks down the oil, after which you can scrub the area and rinse it away with a pressure washer or garden hose.
