Can the silk quilt be sterilized at high temperature on the steamer?

I don't think so Silk is not a chemical fiber. Although the steamer may kill some germs, the water left in it will breed more bacteria, and it is estimated that it will not be used after steaming. In fact, the best way is to wash the quilt cover frequently. Putting the quilt in the sun is the most scientific method. I hope it helps you.
