How to Wash a Sleeping Bag: Simple Tips for a Deeper Clean

Sleeping bags are not just camping gear; they’re memory keepers. From cozy nights under the stars to long road trips and childhood sleepovers, each sleeping bag carries stories, warmth, campfire stories, muddy trails, and comfort. 

However, after many adventures, it is no surprise that they collect dirt, sweat, odours, body oils, and even bacteria from the surroundings. That’s why proper sleeping bag cleaning is not something to overlook.

Unlike regular bedding, sleeping bags are made with insulated layers and delicate fabrics that need special care. Washing them the wrong way can lead to shuffling, fading, or even tearing. 

Whether it is a synthetic, shell-fabricated, insulated, or any other type of sleeping bag, knowing how to wash a sleeping bag correctly can help maintain its fluffiness, warmth, and long-lasting durability.

To safeguard its shape and keep it free from germs, wash the sleeping bag once you return home from a memorable adventure and use an effective cleaning disinfectant, such as Lysol^® Laundry Disinfectant - Crisp Linen, which kills 99.99% of viruses and bacteria that detergents may leave behind^*.

Best way to clean a sleeping bag: 4 easy steps

Learn the right way to care for your sleeping bags, your travel companion in all your outdoor stories.

Step 1: Start with the care label

Before tossing your sleeping bag into the washer, be sure to read the label for all the essential cleaning guidelines. Don’t overlook those important instructions. 

Most sleeping bags are made with sensitive fabrics or insulation that are not resistant to heat, aggressive cycles, or chemical detergents. 

Avoid using hot water unless the label specifically states it's safe. Hot water can damage the shape. When in doubt, stick to cold water and a gentle cycle to protect the comfort and warmth.

Step 2: Unzip, shake, and prepare with care

Before washing, fully unzip your sleeping bag and give it a good rinse. It has been through adventures and probably accumulated dust, leaves, mud, and other dirt. Turning it inside out helps clean the lining more effectively and protects the outer shell. 

Gently place the sleeping bag in the washing machine. It's best to wash it alone or with delicate, featherlight, or lightweight items. Be sure to avoid bulky, heavy, or dense fabrics that could compress, strain, or stress the material, shell, or lining of your bag.

Step 3: Wash gently and sanitize thoughtfully

Add a mild laundry detergent to the load but skip any fabric conditioner, corrosive products, and disinfectants, as they can degrade its material, toughness & stability.

But, to bacteria and viruses that you brought back from your outside trip, remember to include a trusted laundry disinfectant, such as Lysol^® Laundry Disinfectant - Crisp Linen. This disinfectant is gentle on fabric, and works even in cold water to kill 99.99% of viruses and bacteria that detergents may leave behind ^*. 

Wash the sleeping bag on a gentle cycle to ensure thorough cleaning without damaging the fabric, helping it maintain its softness, hygiene, and durability.

Step 4: Let it dry naturally

After washing, avoid using a high-heat dryer, as it can overheat, warp the shell, degrade the synthetic filling, or cause the down to bunch up, reducing its ability to keep you warm. 

Instead, hang it on a clothesline or drying rack in a well-ventilated, shaded area. Make sure it is completely dry inside and out before storing to prevent mustiness and preserve its comfort and warmth.
