How to Machine Wash a Sleeping Bag at Home

If you have access to a large washer, machine washing is a convenient choice.

  1. Check the care label: Always follow the manufacturer’s instructions.
  2. Pre-cleaning: Zip up the sleeping bag fully, secure all Velcro and buckles. Spot clean areas like the hood and collar with a damp cloth and mild soap.
  3. Choose the right machine: Use a front-loading (drum) washer, not a top-loading agitator machine.
  4. Use special detergent: Pick a down-specific cleaner for down bags, or mild neutral detergent for synthetic bags. Avoid bleach or fabric softeners.
  5. Water & cycle settings: Cold or lukewarm water, gentle cycle.
  6. Pro tip: Turn your sleeping bag inside-out (flip it) before washing. This helps remove sweat and body oils from the inner lining, which is the part most exposed to your skin. 

How to Hand Wash a Sleeping Bag

If you don’t have a large washer, hand washing is still effective. 

  1. Fill a bathtub with lukewarm water and add sleeping bag cleaner.
  2. Fully submerge the bag, gently pressing to wash—do not wring or twist.
  3. Drain and refill the tub multiple times until the water runs clear.
  4. Press out water carefully by hand.

How to Dry a Sleeping Bag

Drying is as important as washing. Improper drying can damage insulation. 
First,Use a tumble dryer on low heat or air-dry cycle. Add a couple of clean tennis balls to help restore loft. Every 30–60 minutes, take the bag out, shake it, and if possible, flip it inside-out to speed up interior drying. For clumped fill, gently break it apart with your hands. Drying may take 2–6 hours, longer for down sleeping bags.
After using the dryer, you can lay the sleeping bag out flat again in a ventilated place to dry it to avoid some areas from getting wet and causing mold.
The second method: Direct Lay in well-ventilated area. Turn it regularly to ensure both sides dry completely.
Avoid: Direct sunlight or high heat, which can damage insulation fibers.

Sleeping Bag Care Tips for Longer Lifespan

3.Store it loosely in a breathable storage sack or hang it—avoid long-term compression.
4.Use a ground pad under the sleeping bag to prevent punctures or dirt buildup.
