Rust preventative approved on Boston unwound strings.

[Andrew and Rebeca Anderson]

Hi,
I talked to Kent Webb today about some info needed for a school I'm 
working at and asked about the "grease" I found on the Boston upright 
piano strings

Turns out there is an approved rust preventative utilized on Boston 
piano unwound strings.

Pretty thoroughly applied from my observations.  Evidenced by hammer 
felt and other detritus sticking to the strings. :-\

That's the end of that story.  Getting these pianos stable with 
humidity varying  21% now from 72% Rh (+/- 5% by my instrument) in 
September is another story still being written. :-X

Sincerely,
Andrew Anderson
