Use inexpensive clay cat litter to cover the stain. Use your shoe to grind the clay into the oil stain.
Use a broom and dustpan to sweep up the cat litter. Dispose of the litter as a potentially hazardous waste material. If unsure of how to discard the material, contact the local waste-management company for further directions.
Pour cola on the oil stain. Use a stiff brush or broom to scrub the area. Continue to add soda to keep the area damp for at least 30 minutes. Do not allow the soda to dry.
Use water from a garden hose to rinse the soda from the concrete. A gray stain will remain on the surface.
Mix a cup of chlorine bleach, a cup of laundry detergent and a gallon of hot water. Pour the solution over the stain. Do not use detergents that contain ammonia. Scrub the stain with the mixture and rinse again.
