From continual compression or the build up of sweat and dirt, down can lose loft—reducing the garment’s insulating effectiveness. When your down garment has lost it’s loftiness, it is recommended that this garment be washed. Although necessary, it is best to do it as sparingly as possible. Use a front-load washing machine and a down-specific detergent such as ReviveX Down Cleaner Concentrate. Use warm water on permanent press or gentle cycle and rinse twice to ensure all cleaner has been removed.
Remove excess water with a towel by patting dry. Dry the down garment on low heat with two clean tennis balls to help regain loft. If you don’t have tennis balls, you can substitute a pair of rolled up heavy socks. It is very important that you dry your down garment entirely, which may take upwards of 2 to 3 hours. Your down garment will not regain its loft until it is fully dry. Store unstuffed in a dry place.
