Regarding cleaning: I have cleaned half a dozen Washitas that were covered with black oily grease and locked up deep in their old wooden cases.
a) 140F tap water with Simple Green added in the Ultrasonic for 20min (yes, the ultrasonic)
b) 140F distilled water with a drop of Dawn in the Ultrasonic for 60min (always stabilize PH after cleaning!)
Sure, if there is a crack the stone may break...but if it has a crack, I *want* it to break. I have no interest spending hours lapping a stone, to find a crack forms later. Good stones wont crack IMHO
I have a 2.62 sg Butterscotch found for $10 that looked like slate it was so oily. It's now my favorite finisher
