silk filled comforters ? Take it easy. The following steps will work a lot.
First of all, you need to place your silk duvets on clothesline with its cover for about two hours. But remember not to expose them to the strong sunlight. It’s better to put them in a well ventilated place, which could ensure them to be much fluffier. Then, blot any stains with a damp white towel. Rub dishwashing soap on the stained area and wash them in cool water by hand.
Once having been washed, you could hang the pure silk comforter up to dry. Dryer in low heat can also be used as well.
