Materials such as kitty litter, baking soda, or even dry sand are ideal because they draw the oil out of the concrete and into themselves. Whether the culprit is a leaking vehicle, a spill from maintenance equipment, or tracked-in grease, these stains can degrade the appearance of an otherwise well-maintained surface.
Addressing Oil Stains to Preserve Concrete Integrity
Hold the wand at a consistent distance and angle, moving steadily across the stain. A standard garden hose can remove loose debris, but a pressure washer is the most efficient tool for this task.
Treating Set-In and Stubborn Stains If the oil has already dried or if the stain persists after the initial blotting process, a more aggressive chemical approach is necessary. Allow the absorbent to sit for several hours, or ideally overnight, to soak up the oil.
Maintaining Concrete Integrity in the Presence of Oil Stains
Technique and Settings When using a pressure washer, adjust the nozzle to a wide-angle setting to avoid damaging the concrete surface. The combination of kinetic energy and water flow will emulsify the remaining oil, washing it away down the drain or into a containment area.
