WD40

[Robin Stevens]

I followed a music teacher from school to school for many years who had a
bad habit of applying WD40 to every slightly sticking note he found!! In
every case the WD40 over a period of time reacted with the brass centre pins
causing a green gunk to grow on the pin making it completely  unworkable. I
would stick with Protek. Short term fixes like this, the same as putting a
drop of machine oil on the striking point of a Hammer to soften it have a
habit of biting you on the Butt down the track. ;-((

Well I'm glad it worked for someone else too!   I guess one would only ever 
try it in the case of a probably low-grade piano where "proper" repair is 
uneconomical, where in its current condition it's unplayable, and where the 
customer just doesn't have the means to replace it.
