Rinse the silk with clean water, soak it in half a basin of clean water with a temperature of about 30℃ with a spoonful of vinegar for about 20 minutes, pick it up and hang it in a ventilated place to dry with water, then touch it with your hands to reshape the wrinkled place. When it is half dry, iron the towel lightly with a glass bottle filled with hot water or a low-temperature iron to eliminate wrinkles.
