Go to home depot and ask. There is an acid that is used, but I can't remember the name of it.
I've never had this problem, but I have heard that Dawn dish soap will take care of it.
A big oil spot in the middle of your driveway can make the most meticulously maintained home look dingy. Whether a leak from your car or someone else's created that mark on your concrete driveway, garage floor or sidewalk, it can all be lightened enough as to be barely visible. Try the first suggestion, then work your way down the list as necessary. Whatever you do, don't procrastinate. Bare concrete floors are porous and permanently stain if oil, grease and dirt are not removed quickly. End each remedy by hosing down and air-drying the treated area.
Pour cola on the oily or dry stained areas, and leave the cola on overnight. Squirt a generous amount of dishwashing liquid into a bucket until you have a good lather. Rinse with the soapy water, then with a garden hose.
Sprinkle baking soda or an absorbent powder such as cornmeal or sawdust on the oily spots. If the stain is dry, wet it first to make a scouring paste. Scrub with a stiff brush or push broom.
Sprinkle automatic dishwasher detergent on the oily concrete. Leave it for several minutes, then pour boiling water on the stained area. Scrub with a stiff brush or push broom, then rinse.
Try a commercial concrete cleaner such as Garage and Driveway Cleaner by Red Devil Co. or a grease solvent such as Benzine. Follow the manufacturer's instructions.
Sprinkle trisodium phosphate (TSP) on the oily concrete. If the stain is dry, wet it first. Let it stand for 30 minutes. Scrub using a stiff broom. TSP is a dangerous product; if you must use it, wear rubber or latex gloves, safety goggles and protective clothing. Also, never wash a TSP product down storm drains.
As a last resort, combat tough spills with muriatic acid and a pressure washer. Apply the acid following the manufacturer's directions, and let it soak for several seconds. Follow with a pressure washer set at 2,500 to 3,000 lbs. per square inch (psi), or 176 to 211 kg per square cm. Like TSP, muriatic acid is a dangerous product; likewise, if you must use it, wear rubber or latex gloves, safety goggles and protective clothing, and never wash such a product down storm drains.
After trying any of the strategies above, sprinkle baking soda over the cleaned area to neutralize the solution you've used.
Use cat litter on stain. Also heard putting sand on the oil stains will soak up the oil. Degreaser works
