Hey guys,

I came across a small waterstone a little while ago, and I notice that it has an almost diesel kinda smell to it, and there are very obvious dark stains - like water-colour marks on both sides. Seems like at some point someone added some kind of oil to the stone not knowing the difference I guess..

So my question is: Whats the remedy for oil in a water stone? How can I extract the oil? I've thought of boiling the stone in water mixed with a detergent - but haven't actually tried that yet.. Anyone ever come across this problem before?

Thanks for any thoughts on this.
