Driveway Cleaner

Paint thinner
Cat litter

Pour paint thinner from the can onto driveway spots. Saturate the spots and an area about 12 inches beyond them. Spread a thick layer of NEW cat litter over the entire treated area so that none of the driveway surface is visible. Let the cat litter stand about one hour to absorb the greasy stains. Use a stiff-bristle push broom to sweep up the soiled cat litter. You may need to repeat the process.
