I always used washing machine when I wash my clothes, and because I am always in a rush even those clothes that are supposed not to wash by washing machine, I most of the time include it with the other clothes. And I never like the result.
If you find cashmere on the tag of your clothes, do not use washing machine, it is better if you hand wash it. And use a salad spinner to excess the water.
Do not use washing machine on this kind of cloth because I am sure you will regret it at the end. The cashmere type of cloth is very sensitive. And if you still want to wear your cashmere clothes more than one time, then do not use washing machine.
