<html> Well, Dale, as we say here-bouts........ Nada. Zip. No-ting. We replace the cloth and the pins, and we haven't had any problems. Perhaps our 18% ambient RH helps. Don't know. We've been rebushing S&S verdigris parts for six years, although much more in the last year, and haven't gotten any feedback about re-infection. In years past (30ish), I never had any problem even when I just repinned, so long as I washed the cloth with 1,1,1, TCE. Not the friendliest stuff to have around, but effective and safe when used carefully. If you'd like, I'll send you a sample, and you can try to induce verdigris in your climate. It would be neat to find out, no? I agree that using the high quality original, (often lighter), part is nice when the geometry is right. I really like whips from the teens and twenties. The sandblasting doesn't make them white, and I would hate to use bleach, but they look just fine. All new cloth and skin, burnished jack tips and balance, etc. Again, let me know if you want a sample. I guess that goes for anyone that has a serious interest, although I can imagine Salvador's face when I tell him we need to do another couple of hundred freebies!  Later, Guy Nichols At 11:53 AM 12/27/2005 -0500, you wrote: <blockquote type=cite class=cite cite>  Guy wrote <dl> <dd>     Shameless plug on the wippens.

Steinway curse.     Ahh ,Yes I've done this to shanks including re bushing & it comes back in less than a year,  what a waste of time.  And as  for the wippens  if it comes back then  I've spent $400 for what .......eg-zacctly?  Guy , In principle I love this idea because except for the green shluck these are perfectly good  & expensive Maple parts were all throwing out. Know what I mean?   Maybe we could figure out a cheap way to just cut off the birds eye & insert a new one  with uncontaminated wood & voila I can use all those old parts I've saved for years.   Tell me more about how you neutralized the green schtuff. You got my attention.  again    Sincerely    Dale Erwin</blockquote></html>
