I would agree with Mr. Blees in that the FIRST thing you need to do is take the piano completely apart and give it a complete cleaning. Vacuum it out, blow it with compresset air, wipe out any stained areas, clean under the keys, and clean/blow out the lower back area where dirt likes to accumulate at the bottom of the soundboard. Only then can you really attack the odor issue. You never know-- there might even be something dead in there. Rob Goodale, RPT
