For stains on delicate fabrics like silk, start by gently blotting the area with a clean, damp cloth to remove excess residue. You can also use a mild detergent mixed with water to spot clean the stain. If the stain persists, it’s best to take the Hanfu to a professional dry cleaner who specializes in delicate garments. Make sure to inform them about the specific fabric and embroidery to ensure proper care.
