Mold – how to determine if it’s mold or just wood discolouration; if it’s mold, how do you treat it?
I’m remodelling my bathroom. I just gutted it. I’m looking up at the exposed ceiling. I see the joists (8″ fir) and the floor of the second story. I see that some of the wood has dark marks on it. The wood is not wet/damp (visually or to touch). I don’t have a moisture meter.
How do you determine if it’s mold? And if it is, how do you treat it and ensure it’s good prior to putting the room back together? Not a lot of information on the internet about this topic. I’m including a picture. I did scrub the darker areas with soap and water and then used sand paper/steel wool. The dark colors didn’t come out.
And lastly, any advice on what to use / stay away from re: wall assemblies in bathrooms?
