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 TypeRecommended Frequency
Daily with coverEvery 2–3 months
Daily without coverEvery 1–2 months
Occasional use2–3 times per year
Light stainsSpot 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.


Recommended Brands:

  • Seventh Generation Free & Clear
  • Woolite Delicates
  • Mrs. Meyer’s Clean Day (Fragrance-Free)
  • Method Free + Clear
  • Ecover Zero

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.
