Sprinkle kitty litter over the grease spill to soak up as much of it as possible. Sprinkle until the kitty litter no longer absorbs the grease. Let it sit for 10 minutes to give it time to absorb all the grease stain.
Scrub the kitty litter into the brick with a stiff, nylon-bristle brush. Don’t use a wire-bristle brush, which will scratch the brick driveway.
Sweep up the kitty litter, and throw it away.
Add 2 tablespoons laundry detergent to a bucket of hot water.
Dip the scrubbing brush into the soapy water, and scrub it over the bricks until the grease is gone. Use as much soapy water as possible.
Rinse the brick with clear water from a hose, and let it air dry.
