I'm a bit scared to post this as I'm going to out myself as dangerously slovenly but here goes... We had a big mould patch in our bedroom for (ahem) a little while. I have finally gotten around to tackling it with various potions and it has gone. Unfortunately the mould is also on the curtain next to the wall. I LOVE my curtains - they cost a bloody fortune - so how can I remove the mould without damaging them? DH suggests dry-cleaning; is that wise?
