Clean Green Centers

[David Renaud]

A client has a 100 year old Steinway upright, so sluggish its
unplayable.
The action centers are growing.

Hammer butt centers are terrible.
Wippen, dampers centers are a little discolored but
have far less contamination. Why would this be? Could repeated
lubrication of hammer centers over the years have made things
worse in the long run?

I am rebushing/repinning all double flanges for the lady. This
will make it work. Birds eyes are stained green, will clean out wood
with
alcohol.

I'm curious if the consensus is that all action centers
should be done, not just hammer double flanges, or I could get in
trouble.
