Perchloroethylene (PERC or dry cleaning fluid) seems to work but it is considered a highly toxic substance. Goose juice or other applications that use baltusrol can also be useful-though questionable for the permancence. You need to work the parts (move them a lot with your hands after application) and also control the humidity with a Dampp-Chaser.

There is verdigree in most of the action centers. I have treated them with engine starter fluid, followed by Protek which usually works on grands, but in this case, there are still quite a few flanges that are still a little slow. Any suggestions? (I apologize that I haven't researched to see if this question has already been answered in this forum, but I just joined tonight and I haven't figured out how to use the archives yet.)
