The best way to wash satin fabric depends on what type of fibers are used, but most satin pieces last longer and look better when washed by hand. Dry-cleaning is necessary, however, for satin made with a silk-and-acetate combination.
Satin is created from either silk, acetate, rayon, cotton, nylon or polyester. Water-based washing of a satin garment created with silk and acetate can break down the fibers. Satin made of other types of materials maintains its shape better when hand-washed in cold or warm water with a mild detergent. Machine-washing is acceptable on the delicate cycle. Laying satin flat to dry, avoiding direct sunlight, produces best results.
