Answer 4

It depends on how old the stain is and how much the concrete has already absorbed.  

If the stain is fresh, pour a liberal amount of cat litter, sawdust or Oil-Dri granules (or equivalent) to completely cover the stain.  I like to step on the granules to make sure they get completely worked into the stain.  Let sit for a couple days, then sweep up.  You may also try dry concrete mix.

If the stain is not completely gone or the stain is old, I would recommend a liquid based solution.  Try things around the house first - like detergents or WD-40, then scrub with a brush.  If you have one, try a pressure washer.  If that does not work, then you may have to buy a product designed to remove oil stains from concrete.  One such product is Eximo.  I've read promising things about it on several websites, but it is like $20 a bottle.  check with your local home center for additional products.

Do not use solvents or gasoline, as these may eat or etch the concrete.

Answer 5

Put clay kitty litter on it to absorb as much as you can. Then scrub it good with Dawn dishsoap and HOT water. :)
