Is this mold on my wood window frame? It is several years old and I have noticed tiny black specs that have grown over the last few years?
Everyone says "use bleach" but that doesn't seem right--this mold is in the wood, not on top of it.
What should I do about it? I hope I don't have to replace the window. Is there a way to restore it? If so, how do I find the right person to hire for it?
