I've heard anecdotally that mold will glow green under a black light (UV light). Is this true?
There's a room in my house with a musty odor, and I'm trying to determine the source of the smell. There's a substantial amount of unpainted wood - here is a sample of what it looks like under an ultraviolet light:
(Photo specs: 1s f/4.5 exposure under 2 48" 36W T8 UV lamps.)
Does this indicate mold growth in the wood? (Freshly cut wood exposed to the same UV light does not reflect the same green-yellow color.) I have tried cleaning the surface of the wood with mold/mildew cleaner, to no effect. My understanding of mold growth is limited and I'm having a hard time coming up with reliable information about it.
