Put some newspaper down and pour coca-cola on it. Do the kitty litter grind on the rest.

i've just been using cheapo kitty litter... at the end of a work day dump a bit on and cover it well... spread it... stomp a little... leave it over night... sweep up the next day.

If you grind it up into a dust it will pull the oil out even better. have a big motor and pestle in the garage to I picked up for like a buck to do it. Takes hours not days to get the oil out
I'm with the kitty litter crowd. Grind it in and then let it sit a while, then sweep it up. the remaining stain can be reduced by using powered or liquid detergent. Make a thick paste using a minimum of water, spread it on the stain and then cover it to keep it from drying out. Later just rinse it off. Gets about 99% of the oil. Time gets the rest.

Dammit Dave. You beat me to it....

The kitty litter & sawdust is great for getting any fresh spills, but does little for what has dried. The acid is not a good ide as it provokes erosion and weakens the surface of the cement making it more prone to cracking or chipping.
One product that works well is Genesis 950. Genesis 950 has been used in the printing industry for the past 20 years to remove ink from press equipment, floors and clothing. Because of it's effectiveness, garages, detailers and body shops have begun using Genesis 950 not just to remove oil stains, but also to clean transmissions, interiors, tools and rags.
You can get more info on it at www.amerikalstore.com
Genesis 950 works with water to soak into a stain and break the bonds of the stain. Once a stain's bonds have been broken, the stain can actually be lifted from the surface and removed. This makes cleaning concrete and flooring a quick and easy process. To properly remove grease and oil stains from concrete, mix 1 part Genesis 950 to 7 parts water. Apply this mixture to the stained concrete or flooring and let it soak into the surface for about 2 minutes. After it has soaked into the surface, use a push broom or scrub brush on the area. This will get the mixture into the stain and allow the bond of the stain to be broken. After scrubbing the area, power wash the surface with water and the stain will be removed. For heavier stains, the process may be repeated or the mixture may be allowed to soak on the stain for a longer duration of time.
Being an all purpose cleaner, Genesis 950 can also be used for detailing and interior cleaning. By using the same mixture of 1 part Genesis 950 to 7 parts water, dashboards, upholstery and floors can be cleaned with a sponge. The mixture will take out stains, and clean the interior of dust, dirt and grime. Oil and grease can easily be removed from transmissions, chains, rims, grills, and bodys. It is also the perfect solution for cleaning and restoring convertible tops and vinyl.
Half the battle of maintaining a car is maintaining the garage or your driveway. Removing grease and oil stains can be easy if you know how to do it properly and use the right tools.
crud cutter........
purple power works too, just not as well
Stain the rest of the concrete a consistant color? Don't look down?
If you do it right you can end up with calico driveway. The oil makes black spots, the transmission fluid makes red spots, and the leaky battery makes white spots.

Wow LennyX you sound like an infomercial! Are there any special offers?
several cycles of DriveUp, scrub, wash, pressure wash
Driveways are going to get oil spots. Deal with it. They are a badge of honor.
I used Simple Green and my pressure washer. Took several times to get it clean...
The best way to get your oil out of your concrete is to burn it out. Seriously. One of my companies cleans driveways and garages this way. We have a local service business that performs this service for our clients. Your whole goal to getting the oil out of your concrete should be to dry it out first, then apply your acid to reduce the yellow crystallized carbon stain. If you apply acid on your oil stain without drying it out first, your just going to damage the surface of your concrete only hoping the oil stain will disappear. We apply a 5 step process to get oil out of concrete. First-clean the surface oil with a liquid degreaser, second-burn dry and evaporate the oil, third-very mild acid water mix application, fourth-very mild acid water mix application, fifth-very mild acid water mix application.
I put together some step by step videos showing this entire process that we use everyday on our clients driveway at http://howtoremoveoilfromconcrete.com/. By no means am I coming on here trying to sell my stuff to everybody. If you visit my website, you'll see that I am giving away the entire process in a written step by step guide. However, I do sell the step by step videos if you want to see the process performed rather than read about the process. Just trying to help everybody on this forum...
Don't get oil on the driveway in the first place
