Many people choose to use silk pillowcases to sleep on, believing that it is better for the skin and hair, as well as less allergy-inducing than some other fabrics. Some of these claims are disputed, but there is really no harm in trying silk pillowcases to see if it is enjoyable to sleep on. If not, then no harm has been done. In general, there are few cons cited when using silk pillowcases except the fact that it is pricier than cotton pillowcases, and requires more careful washing, at least initially.
Because the mulberry silk pillowcases are very delicate, it’s recommended to hand wash them. Wash your silk pillowcases in lukewarm water with any non alkaline soap. Rinse thoroughly! You can add pure white vinegar to your rinse water to neutralize traces of alkali and dissolve soap residue. To retain your silk’s natural luster, don’t soak it for more than 3-5 minutes, avoid washing it in very cold or hot water, and never use any harsh detergents that contain bleaches or brighteners. For silk pillowcases in dark color, you’d better wash them separately as the color can come out because of the nature of silk.
Dry your mulberry silk pillowcases fabric naturally by gently squeezing (don’t wring), roll in a towel, and lay it flat to dry. Prevent stiffness by occasionally shaking your silk pillowcases while it’s drying. Don’t use a wooden drying rack, as the dyes & finishes can leave stains.
