I've been battling mold for about two months now. Only I've no clue what's causing it/where it's coming from and what to do about it. It's ONLY in MY office. Which is the very back of the house, and the one room that gets very little traffic. It's ONLY on black fabrics and leather. Nothing else. But not ALL black fabric, because there's a silk tie and a targus backpack that are both black, and in the same area as other stuff that's growing this mold. It ruined my black patrol cap, and it's creeping steadily on my really nice plush chair that I rescued from a yard sale. It cleans off easily, doesn't stain the stuff, but it's growing quickly. I just checked the room about a week ago (shows how often I'm in there) after having cleaned it around two weeks ago and everything was fine. It's green and fuzzy on everything it's on though. Leather book covers, a leather binder, ruined my studded leather belt, on my spur straps, ruined my hat, is ruining a messenger bag, ect. I just found it on the dresser that's in there though, growing on the wood. Not a lot, but little specks of it. It's not on my rifle stock though, which is also wood, and is sitting ON the dresser. It's not on any clothing in there except black clothing. Not on white, blue, ect stuff. I have no clue what to do about this. It's also NOT on the walls, and when we moved in the walls were beige, so if it had been on there when we moved in I would have seen it. If it helps, on the walls in the stairwell to the basement that's behind the closet of this room (lemme know if that doesn't make sense) there IS mildew on the walls, but it's not growing/getting worse and it's not staying damp anywhere in the house that I can tell. I'm just at a loss at this point. I just had to throw away a bunch of my stuff because this is creeping me out. Help?!
