Before you store that down vest or comforter, make sure it’s perfectly clean. Small items can be washed in a front-loading machine, on the permanent press cycle, using a detergent that’s safe for down. If the item is really soiled, stop the machine midway and let everything soak for an hour. To make sure you’ve removed every bit of cleanser, run an extra wash cycle with water only. Use low heat and lots of time for drying. Add a few new white tennis balls to the dryer to break up clumps and restore fluffy loft to the down. Or bring your down to us. Our experts use specialized cleaners and commercial-size machines for perfect results.
