[CAUT] Critter-damaged balance punchings in Yamaha P-22s

[maxpiano]

Some technicians here in the Carolinas who shall remain unnamed found a 
PERMANENT solution.  It may be harder than catching a mountain lion to find 
the insecticide as its distribution as an insecticide was outlawed in the 
1960's or '70's.  If you open a piano that has grayish-white powder under 
the keys, be cautious and do not taste.  It could be arsenate of lead (a 
once-common garden insecticide) mixed with paris green (also an arsenic 
compound, added to disguise the other, which was pink).

I ran across another piano with this about a month ago.
