Don't use anything with water in it on knuckles. The standard way to clean knuckles is with naptha and a small brass bush, outside, with the parts of the action stuff will drip on covered with aluminum foil. Wear your mask and gloves and such, and brush the knuckles with the naptha in the direction that will cause the "nap" to raise so that it will increase friction during jack contact during downstroke of the key, but let the jack slide smoothly back over it when the key is let up. This will "fluff up" the compacted knuckle material some. Then lubricate. Thumpe -------------- next part -------------- An HTML attachment was scrubbed...
