list, This thread sets off my memory searching for the mixture of silicone and xxxxx that the Wurlitzer service dept. poured on the actions for lube. The silicone came in a can and there was a recipe for mixing in other ingredients for this lube. I can see the service team pouring it out of a squeeze bottle with the action out of the piano setting on it's side. We pour it on.... What I'm wondering about this situation is the residual effects of the Wurly Juice formula and whether it is causing the gunk in the bushing at this time. Any memories of this treatment ?
