So I recently got a planet waves humidifier for my Martin and its starting to form what looks like mold on the foam. Is this normal? If not what should I do about it?
I'm no expert, but this seems like the right place to post to me. To answer your question, I don't know...
Chris dont try that here on UG, u dont know what ur doing

to answer your question, Take it to a professional, or just return it
u shouldnt be handleing it man you could die or something? Is the wood inside the guitar molden? Also just replace the humidifier.
