Steinway upright verdigris

[David Love]

I don't use perc mainly for reasons of toxicity and clearly the best
solution is to chuck the parts.  When I did try it, some years ago, it did
free things up for awhile but I never followed up the piano.  Recently I had
a Steinway upright in which chucking the parts simply wasn't an option for
this customer (at least for now) and all we could do was try to free up the
action as best as possible so she could at least play it.  Goose Juice seems
to work the best and last the longest in my experience.  Sometimes spending
the client's money on the second best, even temporary, solution is necessary
until such a time that the best solution can be considered.

Perchloroethylene (PERC or dry cleaning fluid) seems to work but it is
considered a highly toxic substance. 

I have tried perchlorethylene (and many other solvents) by rinsing, soaking,
blowing, and agitating in an ultrasonic cleaner. The centers 

1) get looser

2) never feel right and 

3) ALWAYS tighten back up. Sooner or later, but always.

 

I no longer want to spend the client's money to combine effort with risk,
and just chuck the parts.

 

from Wikipedia:  In the early 20th
<http://en.wikipedia.org/wiki/20th_century>  century, [perchlorethylene] was
the most effective available treatment for hookworm
