Lots of blasting in our subdivision has created some great stepping stones for a project in my yard. I picked out the best and arranged to have them moved to my lot. They used a cherry picker which, unfortunately, was leaking some kind of fluid ...probably hydraulic oil. So each and every stone has large oil stains all over it. The stones are (were) gorgeous. Needless to say, I am totally bummed. Not sure exactly what kind of stone, but one landscaper called them "nice" meaning that was the name of the stone. they are quite varied and are probably not all the same material. (I am in hudson valley, dutchess county, ny area).

Is there anything I can do to remove these stains? If not, I'm hoping that maybe some of them are clean (and flat) when flipped. (they are generally around 5' in diameter and 5-8" thick).

I'm resigned to just not using them and moving on to Plan B (which I haven't figure out yet!!). I know that every time I walk those steps, all I'd see is those oil stains. argghhh!

Thanks.
