Can anyone advise on what to do about mould on my kitchen ceiling? We had a slow leak in the bathroom above which it took a while to get to the root of. That's now fixed but the kitchen ceiling is stained and I've just realised that it's mouldy. Hadn't even occurred to me but potentially it's a health risk. Do I attempt to clean or leave it be and get someone round to repair the ceiling as soon as it's safe to do so?
