Caring for cashmere is more or less the same as washing other wool products. Wash the cashmere on a delicate cycle with cold water and a detergent that is suitable for cashmere. We also recommend putting your cashmeres in a mesh bag to decrease direct impact to the fabric. 

Once again, you should dry cashmeres just like other wools: refrain from wringing the garment, dab the excess water with a towel, and lay flat to dry.
