too stiff

[Erwinpiano]

Hi David

   It is my opinion that the contamination is in the wood not just in the
old cloth.  The contaminant usually , as you know , causes the wood to be
quite discolored and waxy looking.  I have repined an entire set of flanges
on a nice old L(mine) once and within less than a year they were just as
tight as before. Yes treated them with pro-tek and within months the
creeping green scourge returned. And definitely not cost effective.  Oh yes
and have also tried perchlorethelene(dry cleaning fluid) and that as well is
temporary.  So there you have it,the readers digest condensed version of
verdigris removal made expensive and difficult. I've been round the
verdigris cure race track plenty and it's a race none yet can win
  Really though ,what a waste of originally fabulous materials.  If I really
wanted to make money I'd find a real scientific cure for this malady and
retire from the rebuilding business,or, well at least I'd hopefully be more
popular with some.

    Best
    Dale Erwin
