I am about to do a regulating job on a Welmar Grand.  Someone has =
previously rubbed a graphite stick onto the entire area of the underside =
of the key frame as well as the entire keybed.  They obviously did not =
realise that graphite was unsuitable and that only a small portion of =
the two areas actually come into contact.  How do I get the stuff off?  =
