List,

what would you use to eliminate the squeaking of old leather key bushings? I assume nothing that is liquid or greasy? What´s about talkum powder or teflon powder? And what´s about Protec CLP (which is liquid)?

A customer called me today and complained about squeaking. I tuned her piano and eliminated some squeaking 6 weeks ago, but I can´t remember the origin of that squeaking nor what I did to fix it. Given that it was a key squeaking and not an action squeaking I assume that I applied some talkum powder to the leather. If so, it seems that this is not a long lasting solution for that problem. What would be better in the long run?

Maybe that I am completely wrong and that the squeaking had another source, e.g. the center of the jack or whatever.
