You can easily wash your cashmere in a washing machine. Choose a laundry program with short washing and make sure that you do not wash it in water that is warmer than 30 degrees. Use a wool detergent and do not centrifuge the garment. You can also wash the garment by hand. Make sure that you do not wash or rinse the garment under running water, just soak it in water colder than 30 degrees. Buy our cashmere wool wash here:
