A few weeks ago I had an accident where a can of shellac on the top of my shelf in the garage fell and splashed everywhere ... indoor and outdoor. Some of the stuff I was able to clean off, some threw away but the stains on the concrete pad outside the garage door is very visible. Someone suggested denatured alcohol, which I have on two occasions tried and scrub scrub scrub, it seemed to fade a little, but so little it may be just my imagination. Are there anything else I can try to get rid of these stains?
