Guide on Washing a Sleeping Bag at home

Whether it’s a child’s sleepover or an extended camping expedition, ensuring a clean sleeping bag enhances overall comfort. Most sleeping bags can be laundered in a washing machine, or alternatively, washed manually in a bathtub using lukewarm water and standard laundry detergent. For sleeping bags containing down insulation, employing a specialized cleaning solution like Nikwax is advisable.

Below are step-by-step instructions detailing the process of washing a sleeping bag.


Precautions to Consider Before Washing Your Sleeping Bag:

  1. Impact of Dry Cleaning Solvent: Dry cleaning solvents can adversely affect the filler material of a sleeping bag. Always refer to the care tag for specific instructions and avoid using harsh products.
  2. Washing Machine Considerations: Avoid washing your sleeping bag in a washing machine with a center agitator. If your home washer is not large enough, consider using a laundromat or opt for hand washing in a bathtub.
  3. Avoid Harsh Cleaners: When washing a sleeping bag, refrain from using fabric softener, chlorine bleach, or any harsh cleaners. These substances can compromise the integrity of the insulation materials and the water-repellent outer shell.
  4. Inspect for Damage: Before washing, carefully examine the sleeping bag for any ripped seams or holes. Repair these issues beforehand to prevent a potential mess of feathers or filling material during the washing process.
  5. Consider Drying Time: Heavy sleeping bags may take several hours to dry thoroughly. Plan ahead to allow sufficient time, as drying times can extend up to six hours depending on the insulation and size of the sleeping bag.

These considerations ensure that your sleeping bag remains in optimal condition throughout the cleaning process, preserving its performance and longevity for future outdoor adventures.


Guide on How to Wash a Sleeping Bag

Essential Tools and Materials:


  • Washing machine or bathtub
  • Soft-bristled nylon scrubbing brush
  • Automatic dryer, clothesline, or drying rack


  • Liquid laundry detergent or Down wash
  • Wool dryer balls


Expert Guide: How to Wash a Sleeping Bag

1. Preparation of the Sleeping Bag:

  • Separate any removable lining and wash it separately.
  • Fully unzip the sleeping bag.
  • Address heavy stains by applying a small amount of liquid detergent or down wash directly onto the stained area. Gently scrub the cleaner into the fabric using a soft-bristled nylon brush, allowing it to sit for at least 15 minutes before proceeding with washing.

2. Selection of Cleaning Solution and Method:

  • Synthetic fiber-filled sleeping bags can be cleaned using standard liquid laundry detergent.
  • Down-filled sleeping bags require a gentle down wash such as Granger’s Down Wash or Nikwax Down Wash, specifically designed to preserve the feathers.

Both types of bags can be cleaned either by machine or hand:

Machine Washing:

  • Use a front-loading washer or a top-loading washer without a center agitator (or one with a removable agitator).
  • Select the gentle cycle with cold or lukewarm water.
  • Use only one to two teaspoons of detergent or down wash to avoid residue buildup.
  • Wash one sleeping bag at a time and add a couple of large towels to balance the load.
  • After the wash cycle, perform an additional rinse and low-spin cycle to ensure thorough cleaning.

Hand Washing:

  • Start with a clean bathtub.
  • Fill the tub with cold or lukewarm water and add one to two teaspoons of laundry detergent or down wash.
  • Submerge the sleeping bag completely and let it soak for at least 15 minutes.
  • Gently knead the fabric to help release dirt.
  • Drain the tub and refill with clean, cool water for the first rinse.
  • Repeat with a second rinse until no more suds appear.
  • Gently squeeze out excess water from the sleeping bag using a sturdy container for support due to its weight.

3. Drying the Sleeping Bag:

  • For hand-washed sleeping bags, begin by hanging them on a robust drying rack or clothesline to initiate air-drying. Once dripping stops, transfer to an automatic dryer.
  • Use the dryer’s low heat setting only.
  • Include two or three wool dryer balls in the dryer drum to help fluff and evenly distribute the filling.
  • Alternatively, for air drying, lay the sleeping bag flat on a drying rack or clothesline. Periodically reposition the bag and manually break up any clumps in the filling as it dries.


Recommended Frequency for Washing a Sleeping Bag

Regular washing is essential for maintaining cleanliness and performance in sleeping bags, although each wash can diminish insulation and water repellency. Typically, sleeping bags should undergo washing at least once annually. For sleeping bags equipped with removable liners, it’s advisable to wash the liner after each use.

Spot cleaning spills or heavy soil promptly with a damp cloth is recommended to preserve the outer shell. Additionally, while camping, airing out the sleeping bag daily by opening it up and hanging it can help mitigate odors and moisture buildup. For children’s sleep-over bags used frequently, washing after each use ensures hygiene and comfort.


Expert Tips for Maintaining Clean Sleeping Bags

  • Air-Drying After Use: After each use, lay the sleeping bag flat to allow the interior to air-dry fully. This practice helps prevent the development of odors and mildew.
  • Use of Sleeping Bag Liners: Consider using a lightweight liner made from materials like silk, cotton, fleece, or insulating synthetic fibers. These liners not only provide added comfort but also help keep the sleeping bag cleaner.
  • Protective Ground Layer: When setting up your sleeping bag outdoors, lay down a plastic tarp first to shield it from ground moisture and dirt.
  • Ensuring Complete Dryness: Before storing, ensure the sleeping bag is completely dry. Store it in a breathable cotton or mesh bag in a cool, dry environment to prevent the growth of mildew.
  • Restoring Water Repellency: After multiple washes, consider applying a durable water repellent (DWR) product. This helps restore the bag’s water repellency, extending its cleanliness and performance over time.
