Hi all. I have a problem with ceiling mold in the bathroom. The house is seven years old and this has been a problem to a degree for a few years. After every bath/shower the walls are literally dripping with condensation. I make sure the window is always open on the crack. However there is black mold and now an orange-coloured residue, dripping, on the ceiling. No matter what I do I can't get rid of it. It wipes down easily enough and I paint over it with anti-mold paint, but it's back within a week or two. The device in the third pic doesn't seem to do anything, if I'm honest I've never understood how (or if) it works. There's another one in the downstairs toilet. I think the controls for that one at least are in the kitchen, it has a few buttons but none seem to do a great deal as I've spent a while playing with the buttons then going upstairs to ascertain whether anything has happened. At any rate I can't hear if it's on or not regardless of what I do with it!
Any tips? The whole ceiling needs skimming and getting back to its original state but it seems pointless getting that done until the problem is sorted. Thanks.
