[pianotech] mold

[Terry Farrell]

Might not be very effective on keysticks - and certainly not effective  
at all on a vertical music rack. But if the piano is moldy there, the  
rest of the piano is most likely experiencing high humidity also - so  
a DC would likely be of good benefit. But one doesn't really need to  
look that deeply at the situation:  Houston + AC on twice a week = DC  
needed.

If the hammer felts are falling off the cores, the cause is most  
likely poor glue-up exasperated by high humidity. I've seen this  
happen on many Baldwins.
