Finding an oil stain on your colored concrete is disheartening. Whether the oil is on your concrete driveway, garage floor, patio or sidewalk, the stain diminishes the appearance of the entire surface. Blasting the stain with water from the hose isn't enough when it comes to oil. Take a more aggressive approach to getting rid of the stain. Your colored concrete will still be intact, but the unsightly oil spot will be gone.
Spread a generous coating of cat litter, sawdust or cornmeal. Use a broom to spread it around, so the absorbent substance will soak up the oil.
Leave the absorbent substance on the spot for 24 hours. Sweep it up with a broom and dust pan.
Fill a bucket with hot water. Saturate the oil spot with bleach-free, grease-cutting dish soap, then scrub it well with a stiff scrub brush. Pour the bucket of hot water over the spot and scrub the stain again.
Rinse the spot with clean water, then let it air-dry completely. Inspect the concrete once it has dried for any traces of the oil.
Sprinkle bleach-free powdered laundry detergent onto the spot if it's still there. Drizzle water over the detergent, then scrub the paste into the concrete. Let the detergent paste sit on the concrete overnight, then scrub with a stiff scrub brush the next day. Rinse with clean water and let the area dry completely. Repeat this process again, if necessary.
