Before attempting to wash satin items, check the label for cleaning instructions. Most satin is dry-clean only. Silk satin can be handwashed in ice-cold water with mild soap. Satin made from acetate should be washed in warm water with liquid detergent or mild soap flakes. Dunk the garment in the water until the stain is gone. Rinse twice, then drip-dry. Crepe satin should be washed in warm water with mild liquid detergent using the same method.
