After drying, it is very easy to lead to the uneven thickness of the down in the feather clothes, causing the clothes to go out of shape, thus affecting the appearance and warmth. Hang the down jacket in the bathroom, wet it with water, apply the laundry detergent on the down jacket, take a brush or bath ball to brush it, rinse all the laundry detergent, take a towel to dry it, prepare a hanger to gently pat it, shake off the down jacket, and hang it up to dry.
