Hmmmm, it just doesn't stop, does it? A church I service regularly was vandalized. Someone sprayed everything, including the piano, with a dry chemical fire extinguisher. I will be going to service & clean the piano next week. My chief concern is whether the chemical(s) will cause corrosion on the strings - and elsewhere. According to a fire extinguisher web site: "A dry chemical extinguisher sprays a very fine power of sodium bicarbonate (normal baking soda), potassium bicarbonate (nearly identical to baking soda), or monoammonium phosphate." I even found MSDS sheets for these items, but nothing that indicates what it might do to metal. Anyone got any experience with this, or any good ideas?
