Allen asked: "What I found surprising was that this phenomenon could occur in pianos only 4 years old. Joe, are there any manufacturers not using some kind of lubricant (whether emralon, dag, or something else) in spring grooves? They all seem to have something in there. Do you think just cleaning out the grooves (during restoration or even regulation work, esp. on older pianos) and polishing the spring is the best course?" Allen, The short answer: Yes. I like to clean ALL of the "Crap" out of the spring grooves. This eliminates a lot of cussin' later, IMHO. Just because a "manufacturer" does this B.S. doesn't give it credence, IMO. Of course, if I clean all that crud out of the wippens, it is no longer a S & S!<G> Regards, Joe Joe Garrett, R.P.T.
