What is it? Seems to grow out of some wooden areas in the room. I've tried peroxide and bleach. Would a steamer help? Sorry in advance for the bad picture quality.
Borax kills mold and also soaks into wood and stays there to prevent future growth. Bleach does not help on porous surfaces like wood:
"Note that bleach should not be used to kill mold found on wood. While bleach is very effective for killing mold on non-porous surfaces, it doesn’t work well when it comes to wood. This is because the chlorine in bleach can’t penetrate wood, so only the water portion of the bleach gets absorbed.
The mold may appear to be removed from the surface, but it’ll likely continue to grow underneath and return within a few months."
Now I'm interested in trying this on my shower grout. I wonder if it would work the same way. I'll have to check and make sure it's safe on stone and grout.
There really isn't much of a nutrient source, it's growing on a clear coat and it's sporadic. If it was one big spot or a continuous line, that would make more sense to me.
The picture makes it look like a somewhat clean and dry environment as well.
My guess is some kind of chemical reaction, but that is probably wrong.
Thanks. This also sounds like a doable thing. It's annoying cuz it's a living space, so it's likely the spores are getting everywhere. Don't know where it came from either.
White rot fungus, use very diluted bleach (like 5%, a cup of bleach in a gallon of water.) or vinegar (either might alter the wood finish though...), wrap the arm of the chair in paper towels and keep them damp with it for like 30 minutes or so to let it soak into the substrate of the mold inside the wood, and it should just come off with a brush.
Don't let it go everywhere when brushing it off because the more you spread the spores, the more mold you get.
A steamer will likely make it grow more. It'll look like it's working but it'll grow back worse.
Thanks muchly, friend. First time dealing with it. It's worse because it's in a place I don't visit very often. So every time I come back I get a new surprise. :(((
On some pieces of furniture. Not on others. Maybe it needs to spread, maybe the unaffected pieces are better sealed. The place gets marine air, so it's very humid, but enclosed.
Mold growth on furniture is weird. Mold needs two things: moisture and something to eat. Usually if a room has enough moisture, you're going to get mold or mildew on fabric and more porous things before you're going to get it on treated wood. Does the room smell like mold or mildew?
A quick google search seems to indicate that being mold/mildew. You should really check the humidity in your room/building and correct that, offhand it seems to be high if you repeatedly see mold growing there.
