While the outer fabric of your weighted blanket likely is made from cotton or a synthetic fabric similar to the other bedding in your home, fillers used to give the blanket its weight vary, and some of them are more conducive to a toss in a washing machine than others, according to The Spruce. Micro-glass beads are fine in a cold or warm-water cycle, and can be dried on low, but if your blanket is weighed down by plastic pellets, you need to stick to the cold cycle, only, and let it air dry. Weighted blankets made with steel shot beads and smooth pebbles can only be hand-washed and air-dried. To hand-wash a weighted blanket, wrangle in into a bathtub filled with cold water and a half cup of detergent, suggests LoveToKnow.
Meanwhile, if your blanket is filled with an organic material such as rice, corn, beans, or sand, you can only spot clean it; don't even think of giving the whole blanket a soak, The Spruce points out. (Wet beans: need we say more?) For these blankets, it's best to use a washable cover, so that the part that comes in contact with your skin can be tossed in the wash with your sheets and pillowcases on a regular basis.
