[pianotech] Spilled wine

[Joe Wiencek]

Dear list,
I service a Bechstein B, housed in the Consulate General of Germany  
residence in New York City that has a wine stain on the treble bridge,  
where John Negroponte spilled his drink a few years ago.  Of course,  
it looks bad, but the tone is poorer now for this libation.  It is a  
bare wood bridge cap.  I am hoping someone out there might have an  
idea as to how to treat the cleaning.  My concern is that the shape of  
the bridge cap will change or be negatively affected by the cleaning  
process.  I am not sure which is an appropriate method- removing with  
some sort of solution, or sanding, or both?

Any ideas that might help restore our image in the eyes of German  
public?
