Howdy all,
My apartment manager gave me some old hones from the toolshed and one of them looks very promising. No box, no label. It's extremely fine, and just might make a decent finishing hone. The problem is that it had a very heavy coating of grease and dust from years of disuse. I had hoped to able to degrease it and use it with water but so far that hasn't happened. I soaked it for a week in strong 409 cleaner, then a few days in plain water, then another week in 409. It feels totally ungreasy but water just beads up on it like it was wax. Does anyone know a process or solvent for getting the old grease and oil out? I may have to just decide to use it with oil after all but I'd prefer not to.
