We recommend washing your cashmere regularly, preferably in a washing machine and placed in a protective net. Choose a cold wool wash cycle and use a special wool detergent with a maximum spin speed of 500 rpm.
You can also wash your cashmere by hand, taking care not to soak it for too long and rinsing it in clean water. Gently wring it out in a towel. Then dry it flat on a towel away from heat and light and iron it gently without distorting it or pulling on the fabric.
