If you have no time washing silk bedding sets by hands, you can choose to wash them by washing machine just like wash other clothes.
But you need to provide extra attention with silk throw blanket when cleaning them. First of all, the temperature of water should be neither too hot nor too cold, and warm water is best. According to some experts, 30 degree Centigrade (86 degrees Fahrenheit) is perfect. Then, you’d better not use dryer function, and let them dry naturally.
Although washing machine can clean your silk sheet sets and pillowcases, it is still better to wash them by hands.
