How to wash cashmere by hand?

You can wash cashmere with a special detergent for wool, diluted shampoo or even hair conditioner. Make sure washing and rinsing are done quickly. Rinse gently with cold water several times until the water is completely clear. Drain out the rinsing water without wringing, and gently roll your jumper or scarf into a terry towel. Dry your cashmere flat on another dry towel, away from any heat source. If your cashmere has been laid flat and has not been wrung, it will return to its original shape and ironing will not be necessary. And if ironing does seem necessary, turn your garment inside out first and make sure the iron is not too hot. Iron gently, without pressing.
