Also the WD in WD-40 stands for water displacement. It was never designed to be used as much more than a penetrating and water displcaement ( such as in the distributor cap in your car). It is almost guatanteed to start a squeek if sprayed on moving parts in a piano. In action centres it will gum it up by attracting dust etc. Mike Swendsen Calgary> > >
