I recently picked up a vintage thuri for a rather good price, but the wooden case it was in smelled of oil. The stone itself really didn't so I lapped it, but was wondering if there is something else that can be done to ensure there is no oil on it.
I've read that thuri's are somewhat porous (hence the reason not to use oil). Would washing this stone in a bath of soapy water do anything to the hone or anything to get rid of any oil if there is some?
