Most weighted blankets are washable, but "washable" doesn't mean the same thing for every construction. This guide covers the basics of washing a weighted blanket safely, no matter which type you own. A blanket with a removable duvet-style cover is the easiest to keep clean, since you're really only washing a lightweight cover on a regular basis. A bead-filled blanket without a cover is also a washable weighted blanket — it just needs a gentler process and a washer that can actually handle the weight. And if what you're really asking is what makes something a machine washable weighted blanket in the first place, it comes down to the fill: a knitted weighted blanket is technically machine washable as a single piece, but gets significantly heavier once wet, which changes what washing weighted blanket fabric and fill actually looks like in practice. Knowing which type you have is the first step to washing it correctly.
How to Wash a Weighted Blanket with a Removable Cover
If your weighted blanket has a removable cover — like YNM's Original Line — this is by far the simplest setup to maintain, and it's one of the most common reasons people choose a covered blanket in the first place.
- Unzip and remove the cover. The cover is what actually touches your skin and collects dust, sweat, and everyday wear, so it's the piece that needs regular washing.
- Machine wash the cover on a normal or gentle cycle, following the care label — most covers can handle cold or warm water and a standard detergent.
- Tumble dry on low, or air dry, depending on the fabric. Check the care label to be sure.
- Spot clean the weighted insert as needed. The heavier, weighted portion inside rarely needs a full wash if it's protected by a cover — a damp cloth and mild detergent on any visible spot is usually enough.
One YNM customer summed up why this setup works so well: the removable cover makes upkeep so easy, since she just takes it off to wash regularly, and the weighted inner blanket stays clean without ever needing a full wash itself. That's the main advantage of a covered, bead-filled blanket — you're maintaining something closer to a pillowcase than a heavy, bulky insert.
How to Wash a Bead-Filled Weighted Blanket Without a Cover
If your weighted blanket doesn't have a separate cover, washing the whole thing is still very doable — it just takes a bit more care than a normal blanket.
- Check the care label first. Fill material varies (glass beads, plastic pellets, or in some cases organic fillers like rice or beans), and organic fillers usually require dry cleaning only rather than water washing.
- Confirm your washer can handle the weight. Check your washer's maximum load capacity, and remember the blanket will weigh noticeably more once it's wet. If your blanket is on the heavier end (20 lbs or more), a large-capacity or commercial washer at a laundromat is usually the safer choice over a standard home machine.
- Wash alone, on a gentle cycle, in cold water. Washing the blanket by itself keeps it balanced in the drum and avoids straining the machine with mixed loads. Cold water helps protect both the fabric and the fill.
- Use a mild detergent — skip the bleach and fabric softener. Both can degrade the fabric and affect how the beads sit inside their compartments over time.
- A front-loading washer (or a top-loader without a center agitator) is gentler on the blanket. Agitator-style top-loaders can tug at the fabric and stress the seams around the bead compartments.
If your washer isn't a good match for the size or weight, hand washing in a bathtub is a reliable fallback: submerge the blanket in cold water with a small amount of mild detergent, gently work the water through the beads, drain and refill to rinse, and press out as much water as possible before drying.
How to Wash a Knitted Weighted Blanket
Knitted weighted blankets are technically machine washable as one piece — no cover to remove — but that convenience comes with a catch worth planning around. Once the thick yarn absorbs water, the blanket becomes considerably heavier, often more than a standard home washer is built to handle safely. For most knitted blankets, a large-capacity or laundromat machine is the more realistic option for a full wash, and air drying flat (rather than hanging) helps the fabric keep its shape. If this sounds familiar, we cover it in more depth in our Knitted vs. Original comparison, including how the two constructions differ in overall upkeep.
How to Dry a Weighted Blanket
Drying matters just as much as washing when it comes to keeping a weighted blanket in good shape:
- Air drying is generally the safest option. Lay the blanket flat on a clean surface or a heavy-duty drying rack — hanging it on a line can pull the fill unevenly to one side over time.
- A dryer is fine if your care label allows it, but stick to a low or no-heat setting, and remove the blanket promptly once it's dry rather than letting it sit.
- Redistribute the fill periodically while it dries, gently shaking or smoothing the blanket so beads or pellets don't settle unevenly in one section.
- Make sure it's fully dry before using it again — trapped moisture inside a weighted blanket can lead to a musty smell or, over time, mildew.
How Often Should You Wash a Weighted Blanket?
Less often than you might think, especially if it's protected by a cover or you sleep under a top sheet. Most weighted blankets only need a full wash a handful of times a year — roughly one to four washes annually for typical use, unless it's used without any cover on a daily basis. In between full washes, spot-treat stains as soon as they happen and give the blanket an occasional airing out to keep it fresh.
FAQ
Can all weighted blankets be machine washed? Most can, but it depends on the fill and construction. Glass bead and synthetic pellet fills are usually machine washable; organic fillers like rice or beans typically require dry cleaning only. Always check your specific care label.
What actually makes a weighted blanket a "machine washable weighted blanket"? It comes down to the fill and the fabric. A machine washable weighted blanket typically uses glass beads, plastic pellets, or a dense knit rather than organic filler, and a fabric shell rated for regular laundering. If the care label says dry-clean only, treat it as a washable weighted blanket for spot-cleaning purposes only, not full machine washes.
Is it bad to wash a weighted blanket too often? Frequent full washes aren't necessary for most blankets and can add extra wear over time. A blanket with a removable cover is the exception — the cover itself can be washed as often as you'd wash any bedding, since it's the insert underneath that needs infrequent washing.
Why does my washing machine struggle with a weighted blanket? Weighted blankets get noticeably heavier once wet, and many home washers aren't rated to handle that load safely, especially with an off-balance drum. Checking your washer's weight capacity before washing, or using a laundromat's large-capacity machine, usually solves this.
Can I put a weighted blanket in the dryer? Often yes, on a low or no-heat setting, but always check the care label first — some fills or fabrics do better with air drying only.
How do I know if my weighted blanket needs dry cleaning instead? Check the care label. Blankets filled with organic materials like rice, corn, or beans are usually dry-clean only, since water exposure can damage or spoil that type of fill.
