I am trying to clean oil stain from driveway, for a long time,but nothing works.
Answer:
If the driveway is asphalt, you'll end up cutting it out and patching it with a cold patch product if its small and professionally if its large. If the driveway is concrete, soak the stain with WD40 and then wash it away witht he garden hose. To make sure the WD40 doesn't dry out, cover it with sawdust or kitty litter or some such and put a garbage can lid over it for a couple of days. You may have to do this 2 or 3 times for good results.
