If you are going to hand wash your quality silk sheets, then you should read us by the following tips.
Silk bed linens can be hand washed in cool or lukewarm water using a mild detergent such as Ivory soap, or a gentle shampoo dissolved in the water. Wool and silk-specific detergents will not coat the fibers, but generic detergents will. Because silk resists dirt and stains, only a small amount of soap should be used. Silk, like most natural fibers, doesn’t tolerate abrupt changes in temperature very well, so stay with one water temperature throughout the wash.
So, never treat your luxury silk bedding sets like other fabrics. Silk is the gift from nature, and treat it with care as much as you can!
