How to Wash a Weighted Blanket the Right Way, According to Experts

When you're ready to give this item a refresh, pay careful attention to the filler type.

Madeline Buiano is an editor at MarthaStewart.com, sharing her knowledge on a range of topics—from gardening and cleaning to home.

Ideal for combatting stress and anxiety—or for anyone who wants to elevate their lounge or sleep set-up—weighted blankets have become an increasingly popular option for improving comfort. One downside to the heavy blankets, though, is that they can be difficult to clean.

"Weighted blankets weigh anywhere from 5 to 30 pounds," says Luis Zuñiga, laundry expert at Mr Jeff. "These blankets, made of wool, cotton, or thickly woven synthetic fibers, are usually heavy, which is why they require a delicate and special process to prevent them from being damaged."

Due to their weight, these blankets can easily be ruined if they're not cared for properly. But despite their fragile nature, it is possible to give your weighted blanket a thorough clean at home, so long as you use the right supplies and follow our experts' advice.

How to Wash a Weighted Blanket

First things first—always read the care tags. After checking tags and determining washability, you're ready to clean your weighted blanket. You can do so by either machine washing or hand washing.

Materials Needed

• Washing machine, if machine washing
• Gentle detergent
• Fabric softener
• Stain removal agents, if necessary

Before You Start

Before washing your weighted blanket, you should pre-treat any stains. Zuñiga says to start by identifying the make-up of the stain, which will help you figure out what to remove it with. Once you've determined the appropriate cleaning agent, apply it to the stain and scrub with an old toothbrush; then, move on to washing.

• Natural pigment (food, makeup, juice): Treat with white vinegar
• Blood stains or yellowing discoloration: Treat with hydrogen peroxide
• Heavy grease stains: Treat with a degreaser
  

Machine Washing Instructions

The process of machine washing your weighted blanket isn't very different from cleaning other types of bedding, so long as the fibers and pellets are machine-safe.

1. Place the blanket inside your appliance.
2. Select a cool, delicate cycle with a low spin.
3. Add in detergent and a very small amount of fabric softener—about a third of the size used in normal loads, according to Zuñiga. "This will help preserve the fabric and the stability of the garment, whereas using too much softener can make the blanket feel scratchy or stiff," he says.
4. Start your washing machine.

Hand Washing Instructions

As is the case with machine washing, you should check your blanket's care label to see what type of fabric and filler it's made with before washing by hand. If it can stand up to hand washing, Alicia Sokolowski, president and co-CEO of AspenClean, says you will most likely have to do so in your bathtub due to the general size of weighted blankets. "Make sure your bathtub is clean and remove any residue that could potentially stain your blanket," she says. Follow the instructions below.

1. Fill your bathtub with cool to tepid water.
2. Add 1 to 2 ounces of gentle detergent.
3. Agitate the water to evenly distribute the detergent.
4. Add your weighted blanket to the water.
5. Let the blanket soak for about 30 minutes to one hour.
6. Remove the blanket from the tub, and drain the detergent water.
7. Refill the bathtub with cold water and place the blanket back in.
8. Squeeze the blanket to remove residue; repeat this process until there are no suds left in the blanket and the water is clear.

How to Dry a Weighted Blanket

According to Zuñiga, you should always hang dry a weighted blanket as opposed to running it through the dryer. "This will take care of the textile fabric," he says. To air dry, Sokolowski says to lay the blanket out flat, which can be done either on the floor or on a large drying rack that can support the blanket's weight. "If you are laying it out flat on the floor, you should place a sheet or a plastic sheet down first to keep it clean," she says.

Keep the blanket in a well-ventilated area and regularly shake it out to ensure the filling is evenly distributed. "Check on the blanket every so often while it is drying and turn it over on the rack to expose both sides equally," Zuñiga says. "Continue this until it is completely dry."

How Often to Clean Your Weighted Blanket

How frequently you wash your weighted blanket depends on how it's used. "If you place a weighted blanket on top of your duvet cover so that it does not come in direct contact with your skin, you can get away with washing your weighted blanket every couple of months or so," says Madeline Miller, product specialist for The Laundress. "However, if your blanket touches your skin nightly or a pet sleeps on top of it, we'd suggest laundering monthly or biweekly."

Additionally, if your blanket is kept in storage for a month or longer, Zuñiga says it must be washed to avoid the accumulation of dust and germs.

Types of Weighted Blanket Fillers

Ultimately, the method you follow when washing your weighted blanket will vary and comes down to fill type. "Unless specifically tagged 'do not wash,' most synthetic or natural blanket fibers can be laundered in the machine, including wool blends and faux fur," says Miller. "However, certain fill types are not meant to be machine laundered, so be sure to check your blanket's tag and manufacturer recommendations before proceeding with laundering."
