This has been a problem for a while and although i've tried using chemical assault and wiping down, nothing shifted it. So, after a morning spent dismantling the old brown wardrobe in front of the wall (yeah, i know) to give me room for taking off the plaster altogether and replastering.
Is there something i can spray or brush onto the underlying brick to help prevent it returning?
Or do i have a larger problem, as the wall is a gable end, upstairs, above a room where the wall is always cool in summer and bloody cold in winter.
