[pianotech] squeaking leather key bushings

I agree, but Bosendorfer is in your neighborhood, maybe you can check to see what they use. :-)

I am highly in doubt that Ballistol works well in the long run. 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.

  Steve Brady introduced me to Ballistol a couple of years ago. 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.

I have found Ballistol to be great stuff for keybushings. 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.

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.
