We recommend that you machine-wash your cashmeres regularly, preferably in a protective net. Choose a cold wool wash program and use a special wool detergent, with a maximum spin speed of 500 rpm. You can also wash your cashmeres by hand, taking care not to let them soak too long, and rinsing them in clean water. Wring them out gently in a towel. Then dry them flat on a towel, away from heat and light.
