To properly wash a sleeping bag in a washing machine, follow these steps:
- Check the care label for specific instructions.
- Use a front-loading machine on a gentle cycle with cold water.
- Use a mild detergent and avoid fabric softeners.
- Close zippers and fasten any Velcro tabs.
- After washing, air dry the sleeping bag flat or hang it to dry.
- Avoid using a dryer, as it can damage the insulation.
