Use cool or tepid water and your gentle washer setting. Place a small amount mild liquid detergent in water and be sure it is mixed before adding the robe or comforter. Wash on gentle. If possible, spin dry 2 times. Dry in cool or warm dryer with a couple tennis balls if possible, to fluff the down. Re-arrange in dryer a few times. When you are convinced it is quite dry, allow to hang on hanger on shower bar or over a railing for a day just to be sure all down is dry, even in corners.
Preventative Maintenance
Generally, down comforters and pillows should be shaken out daily to restore their loft. With fixed construction comforters (i.e., baffle box and sewn-through boxes), the down will not move from outside its respective box during the shaking. When stripping the sheets off the bed, the consumer also may wish to fluff out the featherbed to give its loft back. Consumers can also tumble dry their down products for a short time to get some extra loft.
