Manufacture of the product appears to have been discontinued in the early 1970s. Occasionally a second dose at a 6 month return tuning visit would be necessary. It was taken off the market because of the nasty chemicals that will cause one to grow two heads and four arms, but I think one of the ingredients has similar properties to Xylene. No doubt the chem-heads will chirp in and provide the gory details. <DIV>                Michael Spreeman <A href="http://www.spreemanpianoinnovations.com/">http://www.spreemanpianoinnovations.com</A></DIV> <HR id=stopSpelling> > From: davidlovepianos@comcast.net > To: pianotech@ptg.org > Subject: Verdigris and Goof-Off > Date: Sat, 20 Oct 2007 09:20:13 -0700 > > While removing some action parts with light verdigris today I had this > brainstorm to put a couple drops of Goof-Off on them to see what happened. > I was surprised to find that the loosened up almost immediately.
