Much to my surprise, I discovered that we actually have a waterstone at work, but I could tell immediately that someone had used oil on it, an assessment quickly confirmed by one of my colleagues.
I suspect that it's ruined, but I'm willing to at least give a shot at restoring it, since it would be nice to have a waterstone in the kitchen. I'm not willing to put a lot of time and effort into it, but
I was told that it happened only once, so it's possible that the oil may not have completely penetrated the stone. Plus it's really dished. I figured I'd flatten it and try soaking it in a dilute degreaser to see if it can be brought back.
Does anyone have any experience with this sort of situation? Any pearls of wisdom?
