Graphite Removal

[A440A@AOL.COM]

 <<  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?   >>

Greetings, 
   An eraser will only  burnish the stuff into the wood.  What has worked for 
me in the past is to turn the keyframe upside down, securely supported (off 
the key pins), 
and use a new, single-edge, razor blade as a small scraper.  It cleans off 
the top .002" of the frame and will remove most of the graphite. Moving back 
and forth, keep the blade as vertical as possible while still being able to 
comfortably draw it along the wood.  I normally clean keyframes like this. 
     Don't fall in love with the razor, when it gets dull, get a fresh one.  
A frame may use two or three blades, but will reward you with clean wood to 
begin an action on. 
   The keybed?  I would use the blades there too, but it sure is easier to 
cut yourself if you get in a hurry and your hand stumbles over the edge.......
