Guy, list, Does anyone know what some kind of green powder inside an older Acrosonic might be? I assume it's something to kill the "pests". It's on the back end of the keys, on the hammers and the top of the dampers. I decided I didn't want to take a chance but would like to know what it might be. It's sort of a Kelly green in color. Avery Avery This may be a product called "Paris Green". I worked @Wadley Piano in Dallas in the late 70's and saw lots of this stuff in older pianos. The store owner (The late Brookin Wadley) told me they used it for Critter control in the "old days". I don't know its composition but caution might be in order.
