Squeaking knuckles - best treatment?

[John M. Formsma]

The micro-fine Teflon powder works, but it might take a couple (or several)
applications for it to remain in the knuckle leather.  I have noticed
squeaking knuckles espcially on Young Chang, but also on a Weber.  Other
cheaper imports as well.  However, I have heard that the problem can and
will exist on all knuckles eventually.

You can get the micro-fine Teflon powder from Bill Spurlock, and I also have
seen it in Schaff's new catalog.

I recently tuned two import grands with significant squeaks on every note as
the key began to be depressed. In neither case did I have the time to pull
the action to confirm diagnosis, but I expect to return and treat the
knuckles.

What is currently the BEST standard practice in eliminating the problem. I
understand that a number of techs are using powdered Teflon products.  Is
there a consensus on using these products?

Thank you,
