I now own a sweater which is dry clean only. I thought it was hand washable (never heard of dry cleaning knitwear) but clearly should have checked the label. I normally put even hand wash knitwear in the machine on a cold wash and haven't had any issues, but I was going to hand wash this one. Would you risk washing it? It's 94% wool, 4% viscose, 4% polyamide. I guess it's the viscose which is the risk?
