I have some massive oil stains in my driveway. In the past few weeks, i've scrubbed with everything imaginable and pressure washed.. still stained.
I bought some stuff called pour-n-restore last weekend, but have only gotten a chance to try it on a test area so far. It seems like the stuff REALLY works. It was $7.00 for a small bottle (2 sq feet coverage) and you just pour it on there and wait about 5 hours and sweep it up (turns to a powder).
I'll post up some pictures once it's done before and after.
