Washing puts additional stress on the cover of the comforter. Inspect it for tears, rips or weak spots before washing.
Check the comforter for any spots. Pay particular attention to the top where the oils from your hands and face tend to accumulate.
Large comforters are often too large for home washing machines. Choose a commercial sized washer at a coin-operated laundromat and set the machine to a gentle, warm cycle. Place the comforter in the machine, add mild detergent to the dispenser, and start the machine.
Place the comforter in a dryer with two tennis balls in a mesh bag. Set the dryer temperature to medium, and dry the comforter. Drying at a medium temperature prevents scorching the down but extends the drying time considerably. Consider line drying the comforter after it tumbles for a while to remove any lumps. Wait at least a month after cleaning before storing the comforter to ensure the down is completely dry and does not mildew.
