How to Wash a Weighted Blanket Without Damaging It
Weighted blankets offer relaxation, comfort, and relief from anxiety and insomnia. But when it comes time to clean them, many owners wonder: Can you actually wash a weighted blanket without damaging it?
The answer is yes — in many cases, but with precautions. Washing a weighted blanket requires special care due to its unique materials, weight, and construction.
In this detailed guide, we’ll break down exactly how to wash a weighted blanket based on its fabric, filler type, and care label instructions. We’ll also cover drying, maintenance, and tips to keep your blanket in top shape for years to come.
Why Weighted Blankets Need Special Care
Unlike standard comforters or throws, weighted blankets contain internal fillers that give them their signature heft. These fillers, like glass beads or plastic pellets, respond differently to water, heat, and agitation.
Incorrect washing can cause:
Clumping or uneven filling
Ruined fabric and seams
Internal mildew or bad odor
Damage to your washing machine
That’s why it’s essential to wash them the right way.
How to Safely Wash a Weighted Blanket
Step 1: Always Check the Care Label First
Before doing anything, read the care instructions on your blanket. Most weighted blankets are labeled with precise guidelines about:
Machine washability
Temperature settings
Detergent type
Drying methods
Some blankets are machine washable, while others are spot-clean only. Never assume.
Step 2: Identify Blanket Materials
Knowing the materials your weighted blanket is made from helps you clean it properly.
1. Fabric Type:
Cotton: Durable, typically machine washable
Minky or plush polyester: Cold water only, gentle cycle
Bamboo or rayon blends: Delicate cycle, cold wash
Linen or wool: May require hand washing or dry cleaning
2. Filler Type:
Glass beads: Safe for machine wash, denser and more uniform
Plastic poly pellets: Safe for gentle wash; avoid heat
Steel shot beads: Very heavy, usually hand wash only
Organic fillers (rice, beans, corn): Spot clean only; prone to mold with water
Step 3: Weigh Your Blanket
If your blanket weighs more than 15-20 pounds, avoid using a standard home washer. It could:
Overload the drum
Damage the motor
Void your machine’s warranty
Instead:
Visit a laundromat with a commercial-size washer
Or hand wash in a tub (see below)
Step 4: Remove the Cover (If It Has One)
Many weighted blankets come with removable covers. These:
Protect the inner layer from sweat, stains, and wear
Can usually be machine washed separately
Reduce the need to wash the inner blanket frequently
Remove and wash the cover using typical bedding care (check label).
Step 5: Spot Clean Before Full Wash
If your blanket only has a small stain:
Mix water with mild detergent
Use a sponge or cloth to blot the spot
Rinse with clean water and blot dry
Air dry completely before using again
Spot cleaning is ideal for blankets that aren’t fully washable or to prolong full washes.
Step 6: How to Machine Wash a Weighted Blanket
If your blanket is machine washable and under 20 pounds, follow this process:
1. Use a Front-Loading Washer
Top loaders with agitators can pull seams or shift filling
2. Cold or Warm Water Only
Avoid hot water, which can damage fabric or fillers
3. Gentle or Delicate Cycle
Reduces stress on seams and fabric
4. Mild Detergent Only
No bleach or fabric softeners
5. Wash Alone
Don’t overload with other items
6. Optional Extra Rinse
Clears out any leftover detergent
Step 7: How to Hand Wash a Weighted Blanket
For larger or delicate blankets, hand washing is safer.
1. Fill Bathtub or Large Basin with Lukewarm Water
Add mild detergent
2. Submerge Blanket Completely
Gently agitate with your hands
3. Soak for 15-30 Minutes
Let detergent break down dirt and oils
4. Rinse Thoroughly
Drain water and refill with clean water
Repeat until water is clear
5. Press Out Excess Water
Never wring or twist the blanket
Roll it in dry towels to squeeze out moisture
Step 8: Drying a Weighted Blanket
This step is crucial. Drying incorrectly can destroy your blanket.
Air Drying (Best Method)
Lay flat on a clean, dry surface
Flip occasionally for even drying
Avoid direct sunlight
Drying rack or clean outdoor sheet works well
Tumble Drying (If Allowed)
Use low heat or air fluff only
No high heat (melts plastic, weakens stitching)
Dryer balls can help keep filling even
Never use high heat unless your care label explicitly allows it.
Step 9: Redistribute Filling After Washing
Weighted blankets have pockets or grids filled with beads. After washing:
Shake the blanket gently
Lay it flat and press each section
Smooth clumps back into place
This restores even weight distribution and comfort.
Step 10: How Often Should You Wash a Weighted Blanket?
It depends on how you use it:
Usage Type
Recommended Frequency
Daily with cover
Every 2–3 months
Daily without cover
Every 1–2 months
Occasional use
2–3 times per year
Light stains
Spot clean as needed
Using a removable cover dramatically reduces full wash frequency.
Best Detergents for Washing Weighted Blankets
Weighted blankets need gentle care, especially when it comes to choosing the right detergent. Using the wrong detergent can damage the fabric, cause fading, or degrade the weighted filling. Here’s what to look for:
1. Choose Mild, Gentle Detergents
Look for detergents labeled “gentle,” “mild,” or “for delicate fabrics.” These are formulated to clean effectively without harsh chemicals that can break down fibers or fillings.
2. Avoid Detergents with Bleach or Optical Brighteners
Bleach and brighteners may seem like good cleaning agents but can weaken fabric fibers, fade colors, and damage the weighted beads or fillings inside the blanket.
3. Use Liquid Detergents Over Powder
Liquid detergents dissolve better in water and are less likely to leave residue on your blanket, helping maintain softness and preventing buildup.
4. Hypoallergenic and Fragrance-Free Options
If you have sensitive skin or allergies, opt for fragrance-free and hypoallergenic detergents. These minimize irritation and are gentler on both your skin and the blanket fabric.
5. Eco-Friendly Detergents
Many eco-friendly detergents are free from harsh chemicals and synthetic fragrances, making them a great option for weighted blankets, especially those made from organic or natural fibers.

Common Mistakes to Avoid When Washing Weighted Blankets
Weighted blankets provide comfort and improve sleep, but washing them requires care to keep them in good condition. Avoid these common mistakes to prolong the life of your blanket and maintain its effectiveness.
1. Ignoring the Care Label Instructions
Every weighted blanket comes with manufacturer instructions. Always check the care label before washing. Ignoring these guidelines can lead to damage, shrinkage, or loss of filling material.
2. Using a Washing Machine That’s Too Small
Weighted blankets are heavy and bulky. Using a small or standard washing machine can strain both the blanket and the machine. If your washing machine isn’t large enough (preferably a front-loading or commercial washer), consider hand washing or using a laundromat with larger machines.
3. Washing Without a Protective Cover
If your weighted blanket has a removable cover, wash the cover separately. Washing the entire blanket frequently can wear out the filling. Use a duvet cover or protective layer to keep the blanket cleaner for longer.
4. Using Harsh Detergents or Bleach
Avoid detergents with strong chemicals, bleach, or fabric softeners. These can degrade the fabric and filling, causing the blanket to lose softness or durability.
5. Washing Too Frequently
Weighted blankets don’t need to be washed as often as regular blankets. Frequent washing can damage the blanket’s materials and filling. Spot clean when possible and wash only when necessary.
6. Drying Improperly
Never put a weighted blanket in a dryer that’s too small or use high heat. High temperatures can melt synthetic fillings or shrink natural fibers. Air drying flat or tumble drying on low heat is best.
7. Not Securing Loose Weights Before Washing
If your blanket contains glass beads or other small weights, ensure they are securely sewn inside the compartments. Loose weights can damage the blanket and washing machine.
By avoiding these mistakes, you’ll keep your weighted blanket fresh, comfortable, and durable for years.
