I've got a long cotton light weight coat that has some mould specks on it. I suspect the dry cleaners will tell me they cannot guarantee they'll come out. The label says 100% cotton. The coat and lining do feel like cotton. The lining of the sleeves feels like polyester or some kind of fake silk. The coatis hot pink and lining is off white. There are no embellishments apart from the poppers which are concealed. I thought I'd use the hand wash cycle on cold with some bio, dry flat and then iron on the reverse or through a muslin. The main danger I can foresee is the dye not being colour fast, but washing cold, maybe with a colour catcher to protect the lining, should help with this.
Any thoughts?
