This video shows you how to clean oil stains from a garage floor using cat litter. Use the cheapest kind you can find and pour it on the stain. Next crush the cat litter into the floor using your feet. For a bigger stain, use more oil and you should let it absorb first. Next use a broom to sweep up the cat litter and the stain should be gone. If it isn't completely removed, just repeat the steps and it should be removed.
