I have dealt with many pianos with mold issues due to lack of proper humidity control, improper storage, leaking roofs, broken pipes, flood waters etc.
I disagree with some of the responses since there are a number of concerns and exposure to some molds can be deadly. Three very bad, moldy pianos caused me to not touch the pianos at all due to the presence of "black mold" in and around the keys, keybed and action.
I had a school contract and could not figure out why all of the pins on the bass end hammer flanges of a Baldwin Hamilton had walked out. I finally had a discussion with the custodian who told me the piano sat in the hallway all summer with no AC while class floors where stripped and waxed. The piano was eventually moved INTO the classroom and the AC was on turbo for a week .... All HVAC was controlled from the Central District office to save on the electric bill

Folks,
Anyone here have experience with mold in pianos? My customer's Yamaha G1 sat in a classroom during the summer recess during a damp season here and with the AC running. When school resumed, the entire classroom, including her piano, was moldy. The school brought in a mold exterminator who fumigated the place but didn't bother to open the piano. So, the mold's still in the piano and arguably posing a risk to the just-fumigated room. It's her personal piano, and the school wants it out of there, at least temporarily. Given the environment, she probably needs to find it a new home anyway, but she has no room for it in her apartment. I haven't been able to get a look at the action, but it plays and sounds fine. The only place I can see mold is on the sound board next to the treble bridge. Her questions:
- How likely is it that the mold that infected the room originated in the piano (the exterminator thinks so)?
- Does topical application of a mold-remover product (e.g. Cory Mold and Mildew Remover or LA Awesome Cleaner) normally address the problem?
- What is available otherwise?
Thanks in advance.
