Cashmere should be washed with good quality wool or cashmere shampoo or a similar detergent. Be sure the soap powder is completely dissolved before putting in the garment. Squeeze the suds gently through the garment, then rinse several times in water of the same hand warm temperature.
To dry… don’t wring or squeeze hard-just lay the garments flat on a towel and ease back into shape – dry naturally away from direct heat such as radiators or sunlight. DO NOT TUMBLE DRY.
