How to Wash a Weighted Blanket
Updated July 2026
The short answer
Three checks decide everything: the care label, the fill material, and whether your washer can genuinely handle the blanket's weight, which its manual, not a rule of thumb, should answer. Many weighted blankets have a removable cover designed to take most of the washing, so start there. When the inner blanket itself must be washed and the label allows it, use a gentle, cold cycle with liquid detergent, no bleach or softener, then dry it thoroughly, usually flat or on the label's low setting. Heavy blankets often belong in a commercial-capacity machine or with a professional cleaner, not your home washer.
Before you start
- Read the care label. Weighted blankets split into machine washable, spot clean only, and dry clean or professional only.
- Identify the total weight and the fill: glass microbeads and plastic pellets are the common washable types; sand, rice, beans, and other organic fills generally cannot be washed at all, because they absorb water and spoil.
- Check your washer and dryer capacity in their manuals. The blanket's dry weight is only part of it; a soaked blanket is dramatically heavier, and overloading strains or damages machines.
- Unzip and remove the cover if there is one. Covers wash like ordinary bedding per their label, and frequent cover washing is the whole maintenance plan for many blankets.
- Plan the wet handling: a soaked weighted blanket is genuinely heavy and awkward. Have a second person or a sturdy basket ready, and lift with the load supported, not dangling from one edge.
Steps: washing a weighted blanket
- 1Wash the removable cover first, separately, per its own label. Often that is all the blanket needs.
- 2Spot clean the inner blanket for small problems. A cloth with diluted mild detergent handles most marks without a full wash.
- 3For a full wash, confirm label and capacity, then wash the blanket alone. Gentle cycle, cold water, liquid detergent, no bleach, no fabric softener.
- 4Use a machine that fits the job. If the blanket fills the drum tightly or exceeds what the manual sanctions, take it to a laundromat's large-capacity machines or a professional cleaner instead of gambling your washer.
- 5Hand wash in a bathtub for label-directed cases. Cool water and mild detergent, pressing the blanket clean, then multiple clean-water rinses and a long, well-supported drain before lifting. Get help lifting it.
- 6Dry per the label. Air drying flat, flipped and repositioned so it dries evenly, is broadly safe. Tumble dry only if the label permits, on low, in a dryer with the capacity to actually tumble it.
- 7Confirm it is fully dry before use or storage, deep inside the fill channels, not just the surface.
Fill types, quickly
Glass microbeads:
The common premium fill; usually washable per label, cold and gentle. Avoid high dryer heat.
Plastic pellets:
Usually washable; heat is the enemy, as pellets can deform in hot water or hot dryers.
Steel or metal beads:
Heavy; the capacity math matters most. Follow the label.
Organic fills (rice, beans, sand, grains):
Do not wash; spot clean only, or the fill spoils and clumps.
Knitted chunky weighted blankets (no beads):
Follow that product's label; many wash differently from beaded designs.
What not to do
- Do not assume a universal home-washer weight cutoff; check your machine's manual and your blanket's label instead.
- Do not wash organic-fill blankets.
- Do not use hot water, bleach, fabric softener, or high dryer heat.
- Do not cram a blanket into a too-small drum; it will not rinse, and it can damage the machine.
- Do not lift a waterlogged blanket carelessly; the weight surprises people, and dragging it by a corner strains blanket seams and backs alike.
- Do not iron a weighted blanket or dry clean it unless the label says to.
What to expect
Covers come perfectly clean easily; the inner blanket, washed correctly, comes out fresh with its fill evenly distributed after a good shake. Washing does not fix broken internal stitching. If beads have migrated through a torn channel and pooled in a corner, that is a repair problem, and washing will make it worse rather than better.
Frequently asked questions
When should I use a laundromat instead of my washer?
Whenever the blanket approaches your machine's rated capacity from its manual, fills the drum tightly, or simply feels like a strain to load. Commercial machines exist for exactly this job.
Can the beads go in the dryer?
On low, only when the label permits. High heat can deform plastic fills and stress seams; air drying flat is the safe default.
How often does a weighted blanket need washing?
With a cover in use: the cover often, the blanket itself a few times a year or after spills. Without a cover, more often, which is a good argument for buying a cover.
Is a weighted blanket the same laundry problem as an electric blanket?
No. The weighted blanket's risk is mechanical: weight versus machine capacity. The electric blanket's risk is electrical, with its own guide and stricter rules.
