I have 2 pure wool blankets, the 'aertex' ones with small holes all over them. They're old and belong to my mother who, unfortunately, smokes. I have the use of them for a fortnight for guest beds but I really want to freshen them up. Interestingly, they smell almost of tar or creosote rather than smoke.
I don't want to pay out £10 odd each to get them dry cleaned but dare I gentle machine wash them? And flat dry them?
