Why not just brush them out a bit with a toothbrush or something. Sometimes, all the leather needs is to take out the "shiney" beat in part or gunk build up.. Then, no chemicals needed at all...

Remember that it is just an oil. I was told to never use grease or oil on leather because it hardens the leather, even when the instant effect is quite good.

Even though I respect him highly as a technician, I have sparingly used it here & there and have been impressed with it (plus it smells good!). I have added it to the magic liquids in my tool kit. I have heard that Bosendorfer recommends Ballistol to lube leather keybushings, but have not confirmed it.

On grands I remove the key upstop rail and tip the action up on end and use a small artist brush to apply a thin coating to the pins. It seems to work as good as anything - and I've tried most of whats out there. I like that its a fairly "natural" product. If I have the keys out of the piano I put it on a small rag and just wipe the keypins. That way you don't put on too much.

John Ross Windsor, Nova Scotia ----- Original Message ----- From: Gregor _ To: pianotech at ptg.org Sent: Saturday, March 21, 2009 9:24 AM Subject: [pianotech] squeaking leather key bushings 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.
