  • 1.  Rust on the key end spades of a lift action (spinet) piano

    Posted 2 hours ago

    My adventure in piano repair today involved replacing the rubber grommets on a Wurlitzer spinet piano.  This grommet fits into a metal spade driven into the end of the key.  I am trying to figure out why some (maybe 10%) of those metal spades were very rusted while the rest were not (ie: zero, zilch absolutely no rust at all).  There didn't seem to be any pattern to it (like what a spilled drink might cause).  Any thoughts on why this might have happened and how I can prevent it from happening again would be greatly appreciated.

    Sounds like mice pee, or maybe cockroaches. 
    There is nothing you can do to stop that, short of getting rind of the animals
