The Leaky Car Disaster
Oil is the nemesis of driveways. But the material you choose determines if the stain is permanent.
Concrete: The Sponge
Concrete is extremely porous and chemically reactive. Oil soaks deep instantly. When you try to clean it with acid or heavy scrubbers, you often damage the cement paste, leaving a rough, etched spot that is cleaner than the rest but scarred. The stain rarely comes out 100% because the oil bonds with the cement.
Granite: The Fortress
A driveway paved with Steel Grey Granite Cobbles is different.
Density: Granite is much denser. The oil sits closer to the surface.
Chemical Resistance: You can use harsh solvents (Acetone, Brake Cleaner, Poultices) on granite without damaging the stone. You cannot do this on concrete or asphalt without eating the surface.
The Removal Protocol for Granite
- Absorb: Use cat litter to soak up wet oil.
- Poultice: Mix baking soda and acetone into a paste. Smear it on the stain 1/4 inch thick. Cover with plastic. Tape it down.
- Wait: Leave it for 24-48 hours. The acetone breaks down the oil, and the baking soda sucks it out like a vacuum.
- Rinse: Wash away the powder. Repeat if necessary.
This method can completely remove a motor oil stain from granite, making it look brand new. On concrete, a shadow usually remains forever.
