How to verbs grease stains within driveway? ...
Answers: use a good degreaser such as simple green and a stiff bristle brush. spray some simple green on the grease stain and let it sit a couple of minutes, next scrub it and rise off and it should be pretty honest. you may have to repeat the steps a few times if it a stubborn stain
If the drive is concrete, I use a powdered laundry detergent sprinkled on the stains and dampened down near water. Let it sit a few hours and after scrub off. Kitty litter will soak up excess grease but will not clean the stain.
