What Causes Oil Stains on Driveways — and How They're Removed
What causes oil stains on driveways is usually simpler than homeowners expect — slow drips from an aging vehicle, rather than one dramatic spill, that soak into concrete's porous surface over months or years before anyone notices the discoloration.
What Causes Oil Stains on Driveways: Where They Actually Come From
Because concrete is porous, oil doesn't just sit on the surface — it migrates into the pores and cures there, which is why an old stain looks darker and more stubborn than a fresh one, and why rinsing alone rarely makes a dent in it.
What Causes Oil Stains on Driveways: Why Pre-Treatment Matters More Than Pressure
Removing an established oil stain relies on pre-treatment, not pressure. A degreasing solution needs time to break the oil down chemically before rinsing, since cranking up water pressure on an untreated stain mostly just polishes the surrounding concrete while the stain stays put.
That's the process to expect from a driveway cleaning visit in Frontenac — pre-treat first, then rinse, so oil staining actually lifts instead of just fading temporarily until the next rain brings it back to the surface.
