A down comforter will last many years if cared for properly. Always protect your comforter from direct contact with body oils by using a duvet cover or by placing between two flat sheets. Launder no more than once every two to three years unless there is obvious soiling; more frequent washing will shorten the life of your comforter.
Machine wash duvet in an oversized machine without a center agitator, using warm water and mild detergent on the delicate cycle. Check seams and fabric before washing; if weakness is evident, do not home launder. In order to fully dry the down clusters and to prevent mildew from forming, thoroughly dry on low heat well beyond the point where the outer fabric feels dry (approximately 3–4 hours). Place a couple of tennis balls or dryer balls inside the dryer to aid in the drying process. Air-dry for an additional 24 hours to release any moisture.
In between laundering, occasionally place comforter outside in fresh air and direct sun to restore freshness. Frequent fluffing will help retain loft.
