Use a front loading commercial washer and dryer. Primaloft products should be washed and rinsed in cold water on gentle cycle with a mild detergent. They should be tumble dried on low heat with tennis balls, turning frequently to avoid scorching. Excessive heat should be avoided. Do not dry clean, bleach, or iron. When machine-washing down comforters, wash separately in warm water, short cycle, high water levels, with a mild detergent. Rinse thoroughly. Be sure to use a machine large enough to accommodate the comforter.
