The Right Way To Get Grease And Gasoline Off Cement!!
Don't use kitty litter to get grease and gasoline stains off of cement--you will never get it all. Instead, use powdered dishwasher detergent. Let it sit for about 10 minutes, then scrub back and forth with a stiff broom before sweeping it away. It will break down the grease and soak it up at the same time.
