Weighted blankets are used for a range of reasons. Studies indicate that these blankets, which typically weigh between five and 30 pounds, “could be helpful for individuals dealing with anxiety, autism, insomnia, and other conditions.” By utilizing deep-pressure stimulation, they calm the nervous system and simulate the sensation of being embraced or held (think: swaddling for adults).
They may enhance sleep quality and alleviate stress, but cleaning them can be a stressful task in itself. While the outer fabric is usually something like wool, cotton, flannel, linen, or rayon, the filling that provides the weight “could consist of microfiber beads, sand, steel beads, pebbles, or grains.” (Other sources mention plastic or “poly” pellets and natural materials like dehydrated food as possible fillers.)
So, how can you properly clean a blanket made from these unique materials?
How to Clean Your Weighted Blanket (Using a Washing Machine)
Here are some key tips. The most effective way to clean a weighted blanket is to use a removable cover, so you can wash that instead of the blanket itself. Don't throw it in the wash for every little stain or spot; try to spot clean when you can. Use a mild detergent and avoid laundry products like fabric softener, bleach, vinegar, baking soda, or salt. Never wash or dry on high heat. Be sure to read the care instructions on your blanket's label, as well as your washing machine's weight limit, advises Kristen Higgins, Henkel's Consumer Product Testing Expert for Laundry. She highlights that most standard machines can handle only up to 20 pounds. Even if your blanket is under 20 pounds, remember that it will become much heavier when wet.
In general, blankets with glass beads are safe to wash in the machine, but those filled with steel beads are less ideal, as the friction between the beads and the fabric can cause damage and leakage. Plastic pellets are washable, but they must be kept away from heat, as they can melt. If you choose to wash your blanket in the machine, Higgins recommends treating stains first, removing any detachable covers or ties, and washing the blanket by itself. Use a gentle cycle with regular detergent and skip the fabric softener, "since it can damage the fabric and add extra weight." She suggests Purex Mountain Breeze, calling it "dependable."
If your blanket exceeds the weight limit of your washing machine, hand washing isn't your only option. Higgins suggests visiting local laundromats to see if they offer commercial-sized machines. If so, you're in luck—but remember, always wash the blanket alone with nothing else.
Air drying is the best option. However, depending on the material, your blanket may be suitable for machine drying. In this case, consider going to a laundromat with larger, commercial-sized dryers. Always use low heat unless the care instructions specify otherwise.
How to Wash Your Weighted Blanket by Hand
If your blanket is too heavy for the washing machine or you prefer not to risk it, hand washing is always an option. Fill your bathtub with lukewarm water and submerge the blanket in a gentle, bleach-free detergent for 15 to 30 minutes, occasionally agitating it with your hands. Afterward, drain the tub and rinse the blanket thoroughly. You may need to drain and refill the tub with clean water a few times to ensure all detergent is removed.
Once you’re done, roll the blanket tightly to remove as much water as possible. Then, lay it flat on a surface to dry, ensuring that the filling is evenly distributed.
When to Opt for Dry Cleaning
If your weighted blanket is filled with natural materials like corn, beans, rice, or sand, it's best to take it to a professional dry cleaner. These natural fillers don’t fare well with water—they can become soggy or moldy, and sand can clump together, making the blanket feel uneven. Wool blankets, which don't react well to water, should also be sent to the dry cleaners.
How Often Should You Clean Your Weighted Blanket?
It varies. If you use your blanket nightly, it (or preferably, its removable cover) should be washed every few weeks to remove sweat, oils, and bacteria buildup. For occasional use, such as during naps or TV time, washing it 4-6 times a year is usually enough. Avoid washing too often, as it can reduce the blanket’s lifespan, damage its durability, and disrupt the even distribution of its filling. Frequent washing can cause wear and tear, increasing the risk of rips and spills from the contents inside.
