Cashmere can be hand washed or dry-cleaned. Since it is a natural fiber, hand washing is recommended and will make your cashmere feel softer over time.
The best way to hand wash cashmere is to use cool to lukewarm water with a mild soap or baby shampoo. Squeeze it gently, but do not wring, then lay your garment flat on a towel to air dry. It is recommended to steam iron any wrinkles, but may use a regular iron set to the lowest temperature. You will love the look and baby soft feel after your newly washed cashmere.
