I went in with a = shop vac, stiff bristle paint brush, a smaller brush, soft rags, and my soundboard cleaner and spent about one hour cleaning. This was on a Yamaha = G2.  We asked the insurance company to keep the file open on this for a couple = of years to see what damage might occur down the road.  There has been no damage.  I do have to say though, it depends on the fire = extinguisher rating and the chemicals in the extinguisher.    Clarence Zeches   -----Original = Message----- From: = caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On = Behalf Of Wimblees@aol.com</fo= nt> Sent: Saturday, October 04, 2003 11:57 = AM To: caut@ptg.org Subject: Re: Fire = extinguisher   <div> <div> In a message dated = 10/4/2003 9:03:31 AM Central Standard Time, algiers_piano@bellsouth.net = writes: </div> <blockquote style='border:none;border-left:solid blue = 1.5pt;padding:0in 0in 0in 4.0pt; margin-left:3.75pt;margin-top:5.0pt;margin-bottom:5.0pt'> Anyone have any advice = about removing dry chemicals from a piano?

From what I = understand the chemicals in fire extinguishers are pretty caustic, and will corrode the string, pins, center pins, it gets into all the felts, etc. In order to = get the piano back into performance condition, it would need to be completely = rebuilt. </div> <div>   </div> <div> When the D on our stage was vandalized, we were able to convince the insurance adjuster that there = was no guarantee that the piano would ever be in the same condition as it is = now. And that is why we needed a new instrument. We got one, and kept the old = one, which I repaired, but it is now our "secondary" concert = piano. </div> <div>   </div> <div> Wim </div> </div> </body> </html>
