As winter has started biting, unfortunately condensation is back and the moisture build up has caused black mold around the window in one of our bedrooms.
Following the instructions carefully and ventilating the room properly - this stuff really works! It’s the only product I’ve seen where you can literally watch the mold dying. It kills it off completely! When spraying, make sure you have carpets/furniture etc covered up and no pets/children around - it’s very strong! It can drip or run down the walls a bit so be mindful.
I left it a month before reviewing and mold hasn’t returned!
