Dirt, sweat, and body grime cause goose down to clump together, reducing the puffiness and warmth of your down gear. So puff it back up with the following tips on how to clean down jackets and sleeping bags:
Handwash in the bathtub using a mild powdered detergent or down-specific cleaner (available from Nikwax, Granger’s, and others).
Never use a top-loading washing machine. The agitator can damage the delicate internal baffles; agitator-free, front-loading washing machines are safe.
If your gear has a water-resistant outer fabric, turn it inside out to help moisture escape.
After thoroughly rinsing and squeeze-drying, run your gear through a spin cycle in the washing machine to force out maximum moisture.
>Dry on low heat in your dryer; add tennis balls to break up the down clumps and speed up the long drying process. Never dry clean down; the chemical process strips it of the oils essential for its puff.
