<html> <body> Hi Dave,                The spray on Teflon works very well.  (TFL50)  The can comes with an extension hose, makes it very easy and fast, to reach the damper springs, and damper spoons. Regards Roger <blockquote type=cite class=cite cite="">Barbara,   I deal with lots of Kawai uprights.  They seem to develop squeaky damper lever springs, spoon-felt interface, and pedals after awhile?  I've begun using teflon powder on all contact points.  A hobby brush works well to get it in the groove (is this also called a grub??) and on the springs, and I've taken to using the tapered end of a felt mute to get between the spoon and the end of the lever so I can apply it to the felt.     The other day I had a "click" when the sustain was depressed that it took me awhile to figure out.  Turns out, the action bracket wasn't wedged tightly enough into the nose-bolt, and was moving when the damper assembly was hoisted by the pedal.    Ya never know....   Dave Stahl Dave Stahl Piano Service 650-224-3560 <a href="http://www.dstahlpiano.net/">http://dstahlpiano.net/</a> </blockquote></body> </html>
