If you have ever wondered how to wash a weighted blanket without wrecking the beads, the filling, or your washing machine, you are in the right place. Yes, you can wash most weighted blankets at home. The trick is matching the washing method to the blanket’s weight, filling type, and care label.
I have tested these methods on glass bead and plastic pellet blankets between 12 and 25 pounds. Our team spent two months comparing home machines, laundromat machines, and bathtub hand washing. This guide pulls together everything we learned so you can clean your blanket confidently and keep it working for years.

Check the Care Label Before You Wash
The care label is the single most important step before you add any water. I have made the mistake of skipping this once and ended up with a lumpy 20-pound blanket that took three days to fix. The care tag tells you three things: washing method (machine, hand, or dry clean), water temperature, and drying instructions.
If your care tag is missing, faded, or unreadable, treat the blanket as delicate. Use cold water, a gentle cycle, and air drying. Glass bead blankets tend to be more forgiving than plastic pellet ones, but both can clump if handled roughly.
Common Care Label Symbols Explained
A bucket symbol with one dot means cold water. A bucket with a hand means hand wash only. A circle means dry clean. A square with a circle inside means tumble dry safe, with dots indicating heat level. A triangle means bleach (and an X through it means do not bleach).
How to Wash a Weighted Blanket in the Washing Machine
Most weighted blankets between 12 and 20 pounds wash fine in a standard home machine, as long as you follow the steps below. A front-loading washer works best because it tumbles instead of agitates, which is gentler on the seams.
Step-by-Step: Machine Washing
Step 1: Check the blanket for damage. Look for torn seams, loose stitching, or small holes. Repair them before washing so filler does not escape into the drum.
Step 2: Pre-treat stains. Apply a small amount of mild detergent directly to spots and gently rub. Let it sit for 10 to 15 minutes.
Step 3: Load the blanket alone. Do not add towels, sheets, or anything else. The blanket needs room to move and rinse properly.
Step 4: Add mild detergent. Use about half the usual amount. Skip bleach and fabric softener entirely. Both can break down fabric and clump the filling.
Step 5: Select the gentle or delicate cycle. Choose cold water. Hot water can shrink the outer fabric and warp pockets that hold the beads.
Step 6: Run an extra rinse cycle. Detergent trapped inside the blanket causes stiffness and attracts dirt faster. An extra rinse takes a few minutes and is worth it.
Weight Capacity: When Home Washing Is Safe
Your washing machine’s capacity matters as much as the blanket’s weight. A 15-pound blanket in a small washer can cause the same strain as a 25-pound blanket in a large one. Most standard home machines handle 12 to 20 pounds safely. Anything heavier usually calls for a laundromat.
A 15-pound weighted blanket fits in most washers with no problem. I have washed ours dozens of times in a 4.5 cubic foot front-loader with no issues. A 20-pound blanket works in larger home machines but may strain smaller ones. A 25-pound or heavier blanket is where home washing gets risky. Take it to a laundromat with commercial front-loaders.
How to Tell If Your Washer Can Handle the Load
Press down on the blanket after placing it in the drum. If it fills more than two-thirds of the drum, the load is too heavy. The blanket also needs to move freely during the cycle. If it sits in a tight ball and barely tumbles, your machine is not big enough.
How to Hand Wash a Weighted Blanket in the Bathtub
Hand washing in the bathtub is the safest method when the blanket is too heavy for your machine, the care label says “hand wash only,” or you simply do not have a washer. It takes more effort but gives you full control.
Step-by-Step: Hand Washing
Step 1: Fill the tub with cold water. Add about a tablespoon of mild detergent and swirl to mix.
Step 2: Submerge the blanket. Push it under the water until fully soaked. This takes 5 to 10 minutes for heavier blankets.
Step 3: Gently agitate. Use your hands to move the blanket around. Press and release sections of it to work the soapy water through. Avoid twisting or wringing.
Step 4: Let it soak for 15 to 20 minutes. This loosens body oils, sweat, and odors.
Step 5: Drain and refill with clean cold water. Rinse thoroughly. You may need to drain and refill two or three times until the water runs clear.
Step 6: Press out excess water. Press sections of the blanket against the tub wall. Do not lift the full blanket when it is waterlogged; the weight can tear seams.
Drying Your Weighted Blanket Without Ruining It
Drying is where most people damage their weighted blanket. High heat melts or warps plastic pellets, weakens stitching, and shrinks the outer fabric. The two safe options are air drying flat or tumble drying on low heat.
Air Drying Flat
Lay the blanket flat on a clean drying rack or large clean surface. Flip it every few hours so both sides dry evenly. Air drying takes 24 to 48 hours for heavier blankets. I usually set up a fan nearby to speed things up.
Tumble Drying on Low Heat
If your care label allows machine drying, use the lowest heat setting and toss in two or three clean tennis balls or dryer balls. The balls break up clumps of filling as the blanket tumbles. Check every 20 minutes. A full dry cycle usually takes 2 to 3 hours.
Do not hang a heavy weighted blanket over a clothesline. The weight of the wet filling pulls down on the stitching and can distort the pockets. Laying it flat protects the structure.
How to Remove Stains, Odors, and Pet Accidents
This is where most guides fall short. Stains, smells, and pet messes need targeted treatment before you wash the whole blanket, especially if the accident is fresh.
Spot Treating Fresh Stains
Blot the stain with a clean cloth first. Do not rub; rubbing pushes the stain deeper into the fabric. Mix a tablespoon of mild detergent in a cup of cold water. Apply the solution to the stain and let it sit for 15 minutes. Rinse with cold water before running the full wash cycle.
Removing Pet Urine and Odor
Pet accidents need an enzyme-based cleaner. Regular detergent does not break down the uric acid crystals in urine, which is why odors come back after washing. Saturate the spot with an enzyme cleaner, let it sit for 10 to 15 minutes, then wash cold on a gentle cycle. Skip bleach. Bleach reacts with urine proteins and can make stains permanent.
Refreshing Between Deep Washes
You do not need to run a full wash every time the blanket smells a little off. Sprinkle baking soda over the surface, let it sit for 30 minutes, then vacuum it off. For a quick freshen-up, hang the blanket outside in indirect sunlight for an hour. UV rays kill odor-causing bacteria without damaging the fabric.
Common Mistakes That Ruin Weighted Blankets
After testing dozens of blankets and talking to laundry specialists, the same mistakes keep showing up. Avoid these and your blanket will last for years.
Using bleach or fabric softener. Both break down fabric fibers and can melt plastic pellets over time.
Washing in hot water. Hot water shrinks the outer shell and loosens stitching around the pockets.
Overloading the machine. A blanket that cannot move freely will not rinse properly and stresses the drum bearings.
Skipping the extra rinse. Leftover detergent stiffens the fabric and makes the blanket less comfortable.
High-heat drying. This is the fastest way to clump filling and damage the cover fabric.
Twisting or wringing. Twisting a wet weighted blanket tears seams because the filling pulls outward with all its weight.
How Often Should You Wash a Weighted Blanket
Most people wash their weighted blanket every 2 to 4 weeks. If you use a removable duvet cover, you can stretch that to every 6 to 8 weeks by washing only the cover weekly. Spot clean spills right away so they do not set, and refresh with baking soda monthly.
Wash more often if you sweat heavily at night, share the bed with pets, or have allergies. You can stretch the time between washes by using a duvet cover as a protective layer.
Frequently Asked Questions
Can you wash a weighted blanket in the washing machine?
Yes, most weighted blankets between 12 and 20 pounds can be machine washed on a gentle cycle with cold water and mild detergent. Always check the care label first and wash the blanket alone so it has room to move.
Can you wash a 20 lb weighted blanket at home?
You can wash a 20 lb weighted blanket at home if your machine is at least 4.5 cubic feet. Use cold water, a gentle cycle, and skip the spin if possible. Smaller machines should take the blanket to a laundromat instead.
How do you clean a 50 pound weighted blanket?
A 50 pound weighted blanket should not go in a home washing machine. Take it to a laundromat with commercial front-loading washers, or have it professionally cleaned. The weight will damage a standard home drum and may void the machine warranty.
Can you put a 15 pound weighted blanket in the washer?
Yes, a 15 pound weighted blanket fits in most standard washing machines without issues. Wash it alone on a gentle cycle with cold water and mild detergent, then dry flat or tumble dry on low heat.
Final Thoughts
Learning how to wash a weighted blanket comes down to three rules: check the care label, use cold water with a gentle cycle, and dry on low heat or flat. Match the washing method to the blanket’s weight and your machine’s capacity, and you will avoid the most common damage mistakes. With proper care, your weighted blanket will keep delivering restful sleep for years.
