Restoring shine to a Yamaha

[Paul McCloud]

HI, Michelle:                  
            Whatever was sitting on the finish (oil, or whatever) must
have softened it.  As an experiment, you might try some Howard’s Finish
Restore (Home Depot has it).  It can help restore a dull finish.  Once a
finish gets to this point, it’s basically toast.  I once tried to buff
out an ebony Kawai that had a similar problem.  I spent many hours
trying different things, wax, different compounds, etc., but nothing
worked.  
            Some pianos have a polyester finish, coated with lacquer.
You might try contacting Yamaha to see exactly what that finish is, and
how to deal with your problem.  
            Good luck.

Hi all.  I recently removed about a ¼ inch of dust from a church’s
Yamaha grand.  There were lots of fingerprints on the fallboard so I
proceeded to put on some Cory polish that specifically states it removes
fingerprints. (By the way, this is a lacquer finish.) Well, it
immediately clouded up, I tried buffing it off, it looked terrible, I
applied some Cory wood cleaner which made the wood look very dull.  I
talked to the Cory people who said it was probably reacting with a
previously applied oil-based polish and I should apply a little Windex
to remove the oil.  When I applied the Windex nothing happened.  The
fall board basically looks like someone removed the shine.  
 
The rest of the cleaning job worked out so well and I’m kicking myself
that this has happened to the fallboard.  Any suggestions are great
appreciated!
