I have seem my previous post on the subject copied and re-copied at least a half dozen times. I was not recommending the turpentine treatment - not now. I was simply telling you what some of us did 60-65 years ago. What I didn't tell you is that I knew one technician who mixed arsenic in unleaded (white) gasoline, and sprayed that stuff in pianos. Talk about RISK and HAZARD!!! I certainly didn't do that! The main thing I made sure of in those by-gone days was that any felts that showed any indication in critter damage, eggs, or whatever, got stripped out, bagged, and burned, and the piano got thoroughly cleaned before the new felts went in. That usually solved the problem. There was one more: If I found broken strings in the low tenor of an upright - i.e., broken down at the bridge, I would usually find a mouse nest under the keys, and some gnawed keys to boot. The bridge was their incline from the lower level to the upper one. They would use the "stairway" as a "toilet". Jim Ellis
