Wash silk by hand in cool water and washing up liquid. Do not soak for more than 4 minutes. Do not rub, do not wring! To rinse the liquid, you can replace the water several times at a similar temperature.
If there is a stain, it is worth using spot treatments.
Do not dry in the sun or in a dryer.
Iron the inside of the fabric only in SILK mode. If the iron / steamer does not have a special mode for ironing delicate clothes, the 2nd heat level will be maximum. Can be ironed for safety through a cotton cloth.
