Hi, I’ve had a bit of a damp issue in my bedroom. There was mould growing on the walls/windowsills, which I think I’ve managed to get rid of. But I’ve noticed there is also mildew on a load of wicker stuff (chest of drawers, a set of shelves, storage baskets etc).Two questions: How urgently do I need to get rid of the mildew? And is it sufficient to spray with isopropyl alcohol for now? I have CFS and don’t have the energy for a big washing/scrubbing job at the moment! Thank you.
