I have a norton India slip stone. As far as I know, I have never used oil on it, but when I went to clean it up after using it (water only) on my 325 DMT, my plate started to get clogged up. I had to use acetone to unclog and clean up my plate. So I concluded that my little slip was oiled at one time or another, and it was concerned by a oily felling on the stone that was never noticed before. I have probably only used it a few times.
So that brought a question. Can I soak it in acetone to maybe get the oil out or am I stuck with this?
P.S. I'm already looking into getting some water stone slips anyway, but I was curious
