Who has the best suggestion for removing oil stains from a concrete driveway? Some of it is old and some is recent. I have tried lots of cleaners but so far no luck. Thanks all....

 

carb cleaner and a wire brush...

 

if you are very careful..muriatic acid (HOME DEPOT)..it will actually etch the concrete if left on to long.
Another thought is to make a pultice (think mud pack) out of concrete mix (the bag stuff) and scrub it into the stain.

 

scrub it with the wire brush, and the carb cleaner!!! +1

 

put kittie litter on it immedietly after it is spilled to stop the oil from staining it in the first place

 

I used a strong cleaner, scubbed with brush then took a pressure washer to it....oil is gone but floor has a faint stain where the oil was.

 

bash that area of concrete with a hammer until the stain is gone....
scrub it with the wire brush, and the carb cleaner..+2

 

they best way is to burn it off with a roofers tourch you can buy one at about any home improvement store and just hook it up to a propane cly from like your grill

 

I would have cleaned it off immediately but it was visitors in a POS pontiac and I didn't see it 'til the next day. Lots of good ideas expressed though,'preciate it....

 

How about engine degreaser?? Or oven degreaser??? Or are these too obvious? I like the sledge hammer approach myself but hey, thats just me!!! Oven cleaner should take care of it no prob, and since its not asphalt you don't have to worry about it eating through your driveway.
