honing out a OLD master cyl and the stones keep getting gunked up. i hate to just keep replacing them. they get a layer of oil like gunk on them and i can tell they aren't doing right. i usually put a tad of brake fluid in to use as fluid but i've never had it do this before. does anyone out there have a way to clean them without messing them up and keeping them flat. thanks, hr
