tuning Steinway uprights

[Ronny Boyd]

At a recent guild meeting with a Steinway rep. The question was asked, "why is it so hard to tune the upper treble on a Steinway?" His answer was to use Protex Prolube on the felt that is just above the "V" bar. He didn't know why it worked but it did. So the next time I tuned a Steinway upright I used the Prolube and by God! It workes!! Don't ask me to give an explanation as to why it works but it does. Has anybody else tried this?
