Have you tried Simple Green?
Another good thing is Tri Sodium Phosphate....make sure you wear gloves, safety glasses and us LOTS of water to rinse it away. http://en.wikipedia.org/wiki/Trisodium_phosphate |
gasoline......... im telling you from expereince.. it works....

Eventually the sun will bleach out the oil stains.

This is from my previous post. Note that the muratic acid is a last resort, and it says to sprinkle on baking soda to neutralize the chemicals.
Instructions Difficulty: Moderate Things You’ll Need: * Muriatic acid (available at a hardware or janitorial supply store) * Stiff Brush Or Push Broom * Garden Hose * Plastic Bucket * Commercial Concrete Cleaner Or Grease Solvent * Cola * Safety Goggles * Automatic Dishwasher Detergent * Rubber Or Latex Gloves * Dishwashing Liquid * Pressure washer (to rent one, look under Pressure Washing Equipment in the yellow pages) * Baking soda, cornmeal or sawdust * TSP Step1 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. Step2 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. Step3 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. Step4 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. Step5 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. Step6 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. Step7 After trying any of the strategies above, sprinkle baking soda over the cleaned area to neutralize the solution you've used. |
Xylene works great for that, especially concrete in the garage. Its pretty much like paint thinner but instead of smeiring it like thinner does it will kindof soat it up. Just pour a puddle.. scrub with a rag, and hang the rang up somewhere safe. Anything that comes into contact with thinner or xylene im cautious of combustion.

Simple green works pretty good, but this orange stuff we had at work worked the best. I just can't remember the name of it.

Might be an idea to wear a filter respirator if using Xylene.
