Washing a silk mask

Hand wash in cool water with a little gentle detergent — one made for silk or wool if you have it.

Swish it, don't scrub. Rinse in cool water.

Roll it in a clean towel and press to take out most of the water, then dry it flat, out of direct sun. Sun fades silk.

Don't put it in the dryer, and don't iron it hot. A cool iron through a cloth is fine if you want it smooth.
