Recently I have switched professions. Got feed up with the lack of professionalism, talent, and overbearing micromanagement by unqualified people in my area. Thus going from sharpening 1-2 times a week, to not touching my stones on over 3 months. Apparently I didn't put them away completely dry last time using them and my flattening plate got ridiculously rusted on me. It also embedded rust on a 1k GS it was paired up against. Is there anything I can do to restore the plate or is it a gonner?
