Water stains on silk can be a frustrating problem, but there are a few simple steps you can take to remove them. First, blot the stain with a clean, white cloth to remove any excess water. Next, apply a small amount of white vinegar to the stain and blot it gently. If the stain is still visible, you can try using a mild detergent mixed with water. Apply the detergent solution to the stain and blot it gently. Finally, rinse the area with clean water and blot it dry.
It is important to act quickly when you get a water stain on silk, as the longer the stain sits, the harder it will be to remove. If you are unable to remove the stain yourself, you can take the garment to a professional cleaner.
