Silk items should be hand washed in warm water with a gentle washing solution (made for wool) or a gentle shampoo. Silk fibers are not unlike human hair, and I often use a gentle cream rinse as well. These items have been steamed and the colors are set – but there may still be a minimal amount of color released in the first few washings. Do not wash with laundry detergent as it can be too harsh on the delicate silk; and DO NOT wash or dry in a machine.
When finished washing, pat the item with a towel to remove excess moisture, and hang to dry. When dry, or while still damp, the silk item can be ironed at a silk/wool setting. Take care not to hang silk in direct sunlight for long periods of time, as even colorfast colors will fade.
Note: Greasy stains on silk clothing can often be removed without washing by shaking on some baby powder or colorless talcum powder and lightly rubbing it in, then brushing it off with a clean cloth.
