If you’re wondering how to wash a weighted blanket without damaging it, you’re not alone. These cozy sleep aids are amazing, but cleaning them takes a bit of know-how. I’m gonna walk you through everything you need to do to keep your weighted blanket clean, fluffy, and functional without any issues.
Whether you use it for anxiety, stress relief, or just better sleep, a weighted blanket needs the right care. Let’s dig into the best way to wash a weighted blanket based on its fabric, filler, and weight.
Properly Washing a Weighted Blanket
Washing a weighted blanket the wrong way can ruin its structure, comfort, and lifespan. Here’s why it’s important to do it right.
Weighted blankets are filled with materials like glass beads or plastic pellets, and wrapped in fabric like cotton, fleece, or minky. If washed improperly, these can clump up, leak, or degrade, making your blanket lumpy, less effective, or downright uncomfortable. Plus, some fabrics shrink or wear out fast with the wrong detergent or water temperature.
Check the Care Label
Before doing anything else, I always check the care label—and I highly recommend you do the same. Every weighted blanket has its own set of washing instructions depending on the manufacturer, weight, and materials used. Skipping this step is like driving without GPS. You might get where you’re going… or you might end up in a mess.
Machine Washing a Weighted Blanket
If your blanket is under 20 pounds (around 9kg) and machine-washable, here’s how I recommend washing it safely.
Not all washing machines can handle the bulk of a weighted blanket, especially if it’s heavier. A large-capacity front-load washer is ideal. Avoid top-loaders with agitators—they can damage the fabric or shift the inner fill.
Steps for Machine Washing a Weighted Blanket
- Use cold or warm water (not hot)
- Choose a gentle or delicate cycle
- Use a mild detergent (avoid bleach or fabric softeners)
- Wash it alone to avoid overloading
If your blanket is too heavy, consider going to a laundromat with commercial washers. I had to do that once for my 25 lb (around 11.3 kg). blanket and it was worth the hassle.
Hand Washing a Weighted Blanket
When your blanket isn’t machine washable or is just too delicate, hand washing is the safer bet.
Fill a bathtub or large basin with cold or lukewarm water. Add a small amount of gentle detergent. I like to swish the water around first to mix it before submerging the blanket. Gently knead and swirl the blanket for 10–15 minutes. Rinse thoroughly to remove all soap.
Key things to remember:
- Don’t twist or wring the blanket
- Press water out gently using your hands
- Rinse until the water runs clear
Hand washing may take time, but it’s perfect for blankets made with sensitive fabrics like silk blends or wool.
Dry Weighted Blanket Without Damage
Drying is just as crucial as washing when it comes to preserving your weighted blanket. High heat can melt synthetic fillers or shrink the fabric. If your blanket is safe for the dryer, always use a low heat or air-dry setting.
Drying tips:
- Tumble dry on low or no heat
- Add clean tennis balls or dryer balls to maintain fluffiness
- Avoid using dryer sheets
For blankets that aren’t dryer-safe, I lay them flat on a clean surface like a drying rack or across several chairs. Make sure to flip it occasionally so it dries evenly. Hanging it on a line isn’t ideal—it can pull on the seams due to the weight.
Spot Cleaning for Small Stains
If you spilled coffee or dropped some food, spot cleaning is all you really need.
I mix a little water with mild detergent and dab the stain with a soft cloth or sponge. Rubbing can spread the stain or mess up the fibers. Gently blotting is the way to go. Always rinse the area with clean water after and let it air dry.
Spot cleaning is perfect for those quick accidents in between full washes.
Can You Wash a Weighted Blanket With Glass Beads?
Yes, but you’ve gotta be extra cautious.
Glass beads are more durable than plastic pellets and can usually handle machine washing better. Still, it’s smart to stick to cold water and gentle cycles. Also, glass adds more weight, so be mindful of your washer’s load limit.
If your blanket weighs over 20 pounds, I recommend taking it to a professional cleaner or laundromat.
Tips to Keep Your Weighted Blanket Cleaner Longer
Want to reduce how often you wash a weighted blanket? These simple habits can help.
- Use a removable duvet cover – it’s much easier to wash
- Don’t eat or drink in bed (I learned this the hard way)
- Wash your sheets regularly
- Keep pets off the blanket
- Store it properly when not in use
By keeping it cleaner longer, you reduce wear and tear from constant washing.
When Should You Wash a Weighted Blanket?
This depends on how often you use it and whether you use a cover.
If you use your blanket every night without a cover, washing it every 3–4 weeks is ideal. With a cover, you can stretch it to every couple of months. If someone’s been sick, or you’ve had spills or stains, wash it sooner.
Keeping a cleaning routine not only keeps it fresh but also helps avoid odors and buildup of sweat, oils, or dust mites.
What to Avoid When Washing a Weighted Blanket
I’ve seen a few common mistakes that can ruin even the best blankets. Here’s what not to do.
- Don’t use bleach or harsh detergents
- Never wring or twist the blanket
- Avoid hot water unless the label says it’s okay
- Don’t hang a heavy blanket from one end—it can stretch the fabric
- Skip the dryer if the blanket isn’t rated for it
These slip-ups can lead to permanent damage, so it’s better to play it safe.
Final Thoughts
Washing a weighted blanket doesn’t have to be intimidating. As long as you know the fabric, filler type, and weight, you can clean it safely and keep it feeling like new. Whether you’re machine washing, hand washing, or just spot cleaning, it all comes down to gentle care.
A clean weighted blanket helps you sleep better, feel cozier, and enjoy its therapeutic benefits longer.
