FWIW, I had a piano that had been treated with some kind of elixir (probably WD-40), that was all but frozen. It was a large old upright. I used solvent on the centers, and blew out the residue with compressed air. I found that as I was doing this, that residue was exuding from the bottom of the flange through the pores of the wood. Apparently whatever had soaked the flange was coming out from the compressed air. Simply saturating the flange bushing wasn't enough, but after blowing it all out, the action returned to playable condition (it's been over 2 years since). YMMV.

I my Experience won't last more than about a year. AMHIK Dadle: 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 usefulthough 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.
