Things You'll Need:
- Granger's Down Wash Plus Granger's G-Wash Cleaner Plus (optional) Front-loading washing machine Low-temperature dryer
-
Step 1
Purchase Granger's Down Wash Plus, which Marmot recommends for its Gore-Tex fabrics. Normal laundry detergents are not suitable for Gore-Tex as they may leave a residue on the fabric, which may ruin it.
-
Step 2
Head to your local laundromat with your sleeping bag. You'll need to use a large-size front-loading washing machine.
-
Step 3
Place the sleeping bag in the machine with the Granger's Down Wash Plus detergent.
-
Step 4
Choose warm water for both the wash and rinse cycles. Marmot does not recommend using hot or cold water.
-
Step 5
Place your sleeping bag in a low-temperature dryer after the wash and rinse cycles are complete. Marmot recommends placing two unused tennis balls into the dryer to help fluff the bag and keep clumps of down from forming in the bag.
-
Step 6
Make sure the sleeping bag is completely dry before removing it from the dryer. It may take four to six hours to completely dry.
