Cashmere can be hand-washed, dry-cleaned or washed on a wool setting in the washing machine. You can prolong the life of cashmere by wearing a vest/slip underneath, to reduce washing frequency. Use a mild detergent, always wash very gently in cool water and never wring the knit. Never use softener (this can "felt" the knit).Reshape the garment while it's damp,and dry flat on a plain towel.Store cashmere over the winter by wrapping in acid-free tissue and storing in boxes with cedar blocks/lavender to deter moths.
