Terry, Goose Juice will maintain a piano with yearly treatments and since the piano should be tuned at least yearly------- Joe Goss imatunr@srvinet.com www.mothergoosetools.com ----- Original Message ----- From: "Farrell" <mfarrel2@tampabay.rr.com> To: <pianotech@ptg.org> Sent: Tuesday, June 25, 2002 1:36 PM Subject: Re: Slow hammer return > If the piano has verdigris, I think the conventional wisdom dictates a new action. > > If it does not have verdigris, I have had excellent luck shrink-treating the action centers, and if needed, follow-up with Protek CLP, and if still needed, naphtha and mineral oil.

I heated the hammer butt centers with a hair dryer, which freed up the hammers for about 1 hour. The questions is what do you think is the most reliable way to free up sluggish hammers without replacing center pins or parts? Should I use silicone and naptha, alcohol and methanol or install a Dammp-Chaser heater bar with a humidistat? > > Thanks, > Arthur > > >
