Sometimes all your sleeping bag needs is a spot cleaning and not a full wash. Washing your sleeping bag subjects it to wear and tear and can decrease the loft, we recommend spot cleaning as your first line of defence.
Make a paste of a little non-detergent soap and water and use a toothbrush to gently clean the shell. Focus on the hood and collar where your hair and skin oils tent to accumulate. By holding the shell or liner fabric away from the insulation, you can wash and rinse the area without getting the inside fill wet.
Unless your bag has become unusually dirty, you can typically go many years before a complete wash.
If you feel it’s time to wash your synthetic sleeping bag, please follow these steps:
Woods recommends that you use a commercial sized, front loading washing machine to wash your synthetic sleeping bag.
1. Make sure your washing machine is front-loading with a gentle cycle. Top-loading machines with a central agitator can cause damage to your bag.
2. Close all zipper on your bag.
3. Wash in warm water with a mild non-detergent soap that is made for synthetic-filled items. Wash in warm water on a gentle cycle.
4. Rinse several times to remove all the dirty, soapy water. An extra spin cycle will also effectively remove excess water.
5. Line dry or tumble dry on no heat. Drying might take up to several hours.
6. During the drying process check the bag frequently to be sure the fabric is not getting too hot.
7. Be sure your bag is completely dry before storing.
