We do not recommend wet or dry cleaning of our silk filled products. This is because we use grade AAA silk that contains hardly any impurities. Any washing and dry cleaning may introduce impurities and clumps. For all of our silk filled products, it is meant to use with a removable cover such as your duvet cover or pillowcase. If for example, you spilled wine on your comforter or pillow, you can do a spot clean. Using a mixture of white vinegar/baking soda and cold water will help to remove most stains. Once or twice a year, air it out in the sun for about an hour or two to remove residual moisture and to refresh your silk comforter and silk pillow.
