Washing a Weighted Blanket: Safe Methods for Every Material and Weight

Weighted blankets offer comfort, anxiety relief, and better sleep — but they also require special care. Washing one incorrectly can ruin the fabric, damage the inner filling, or reduce its lifespan. This detailed guide explains exactly how to clean a weighted blanket safely and effectively, depending on its material, weight, and construction.

Whether yours is filled with glass beads, plastic pellets, or something else, you’ll find everything you need to know to keep it fresh and functional.

Why Washing a Weighted Blanket Is Different

Weighted blankets contain much more mass than typical bedding. Their construction involves internal compartments filled with materials that don’t react well to heat, harsh detergents, or agitation. That means:

You can’t just toss it in the washer without reading the label
Some require hand-washing or spot cleaning
You may need a commercial washer for heavy blankets

Taking shortcuts can lead to ripped seams, clumped fillings, and bad odors that won’t go away.

Step 1: Check the Label First

Before doing anything, read the care label. It will tell you:

If the blanket is machine washable
The recommended water temperature
Whether tumble drying is allowed
Special care instructions for materials or fillings

Never ignore the label, especially for weighted items.

Step 2: Know Your Blanket’s Materials

Not all weighted blankets are created equal. Cleaning method depends heavily on:

1. Cover Material

Cotton: Usually machine washable; use gentle cycles
Minky or plush: Needs cold wash, gentle detergent
Bamboo or rayon blends: Cold wash, delicate cycle
Linen or wool: May require hand washing or dry cleaning

2. Filler Type

Glass beads: Machine washable, heavier but durable
Plastic poly pellets: Machine washable, but no hot water or heat drying
Steel shot beads: Rare, but heavy; may need professional cleaning
Organic fillers (rice, beans, sand): Spot clean only — moisture can lead to mold

Step 3: Is the Blanket Over 15 Pounds?

If your weighted blanket weighs more than 15-20 lbs, don’t use a standard home washer. It can:

Throw off the drum balance
Stress the motor
Damage the washer or blanket

Instead:

Use a commercial-size washer at a laundromat
Consider hand washing in a bathtub (see instructions below)

Step 4: Remove the Duvet Cover (If It Has One)

Many weighted blankets come with removable covers that can be washed separately. This saves wear and tear on the inner blanket.

Wash the cover just like any bedding:

Cold or warm water
Mild detergent
Tumble dry low or hang to dry

This is especially useful for everyday dirt, pet hair, or spills.

Step 5: Spot Clean First

Before washing the whole blanket, take care of any specific stains or spots.

How to spot clean:

Mix warm water with a small amount of gentle detergent
Use a soft cloth or sponge
Dab the stain gently —don’t rub hard
Rinse with clean water and blot dry

Let the area air dry before washing the entire blanket.

Step 6: How to Machine Wash a Weighted Blanket

If the care label says it’s safe to machine wash, here’s how to do it right:

1. Use a Large, Front-Loading Washer

Top loaders with agitators can tangle or damage the blanket

2. Wash Solo

Don’t overload with other clothes or linens
Even distribution of weight helps protect the washer

3. Select Gentle Cycle

Use cold or warm water (never hot)
Choose “delicate” or “hand wash” setting

4. Use Mild Detergent

Avoid bleach, fabric softeners, or harsh additives

5. Optional Extra Rinse

Helps remove all detergent residue

Step 7: How to Hand Wash a Weighted Blanket

If the blanket is too heavy or labeled “hand wash only,” follow these steps:

1. Fill a Bathtub with Cold or Lukewarm Water

Add a small amount of gentle detergent

2. Submerge and Gently Agitate

Move it around by hand
Avoid twisting or wringing it out

3. Soak for 15-30 Minutes

Let detergent work into the fabric

4. Drain and Rinse Thoroughly

Refill with clean water
Repeat until water runs clear

5. Press Out Water Gently

Roll in large towels to absorb excess water

Step 8: Drying a Weighted Blanket

This is just as important as washing. Improper drying can damage the filling or cause mildew.

1. Air Drying (Recommended)

Lay flat on a clean surface
Flip occasionally for even drying
Avoid direct sunlight (can fade fabrics)
Use a drying rack or clean sheet outdoors

2. Tumble Drying (If Label Allows)

Use low heat or air fluff only
Check frequently to prevent overheating
Add wool dryer balls to help circulate air

Never use high heat, which can melt plastic pellets or damage stitching.

Step 9: Fluff and Redistribute Filling

After washing, fillings may shift. To restore shape:

Shake the blanket gently
Lay it flat and press evenly across sections
Smooth out any clumps

This is especially important for bead-filled blankets with stitched compartments.

Step 10: How Often Should You Wash a Weighted Blanket?

It depends on usage:

With a cover: Every 3–4 months
No cover: Every 1–2 months or when dirty
Spot cleaning: As needed

If you sweat a lot or use it nightly, wash more frequently.

Special Considerations

1. Memory Foam Weighted Blankets

Can’t be submerged
Spot clean only
Use removable covers for easy maintenance

2. Children’s Weighted Blankets

Check more often for spills or allergens
Always verify fill material and washing method

3. Weighted Comforters or Quilts

These may require professional dry cleaning
Read label carefully

Best Detergents and Washing Tips for Weighted Blankets

Weighted blankets provide comfort and relaxation, but caring for them properly is essential to keep them clean and in good condition. Choosing the right detergent and washing method ensures your blanket lasts longer without damaging the fill or fabric.

Best Detergents for Weighted Blankets

Mild, Gentle Detergents: Use detergents labeled “gentle” or “for sensitive skin.” These are free from harsh chemicals, dyes, and fragrances that can degrade the blanket’s fabric or irritate sensitive skin.
Free of Fabric Softeners and Bleach: Avoid detergents with added fabric softeners or bleach, as these can break down fibers and affect the blanket’s durability.
Eco-Friendly Options: Natural or plant-based detergents are a great choice if you want an environmentally friendly and baby-safe option.

Washing Tips for Weighted Blankets

Check the Care Label: Always read the manufacturer’s washing instructions first. Some weighted blankets require hand washing or dry cleaning.
Use Cold or Lukewarm Water: Hot water can damage the fabric or cause the filling beads to break down.
Gentle Cycle Only: If machine washing is allowed, select the gentle or delicate cycle to minimize stress on the fabric and filling.
Avoid Overloading the Washer: Weighted blankets are heavy and bulky, so wash them alone or with a few lightweight items to prevent damage to the washing machine.
Use a Front-Loading Washer if Possible: Top-loading washers with agitators can be rough on weighted blankets; front-loaders are gentler.
Spot Clean When Possible: For small stains or spots, clean only the affected area with mild detergent and a soft cloth to reduce frequent full washes.

Drying Tips

Avoid High Heat: High temperatures can damage fabric fibers and the weighted filling inside.

Air Dry Flat: Lay the blanket flat on a clean surface to air dry. This helps maintain the shape and prevents the filling from clumping.

Low Heat Tumble Dry: If using a dryer, use the lowest heat setting and add dryer balls or clean tennis balls to help fluff the blanket.

How Often Should You Wash Your Weighted Blanket?

Weighted blankets are cozy and comforting, but like all bedding, they need regular cleaning to stay fresh and hygienic. However, because they are heavy and delicate, it’s important to wash them the right amount to avoid damage.

Recommended Washing Frequency

Every 3 to 6 Months: For most weighted blankets, washing every 3 to 6 months is sufficient to keep them clean, unless they get visibly soiled or stained.
More Frequent Washing if Needed: If you use your weighted blanket daily, especially during hot weather or if you sweat at night, consider washing it every 1 to 2 months.
Spot Clean Between Washes: For small spills or stains, spot cleaning with a mild detergent is a good alternative to frequent full washes.

Factors That Affect Washing Frequency

Usage: Daily use means more frequent washing to remove body oils, sweat, and dust mites.
Allergies or Asthma: If you or a family member has allergies, washing your weighted blanket more often helps reduce allergens.
Pets: If pets sleep with you or on the blanket, wash it more frequently to keep pet hair and dander away.
Cover Usage: If your weighted blanket has a removable cover, wash the cover more often (e.g., every 1-2 weeks) and the blanket itself less frequently.

Common Mistakes to Avoid When Washing Weighted Blankets

Weighted blankets need special care during washing to maintain their durability and comfort. Avoid these common mistakes to keep your blanket in great shape:

1. Washing Too Frequently

Over-washing can wear down the fabric and damage the weighted filling. Stick to recommended washing intervals unless the blanket is visibly dirty.

2. Using Harsh Detergents or Bleach

Strong detergents, bleach, or fabric softeners can break down the fibers and affect the blanket’s texture and weight distribution.

3. Ignoring the Care Label Instructions

Each weighted blanket may have specific washing guidelines based on its materials and fill type. Always follow the manufacturer’s instructions to prevent damage.

4. Overloading the Washing Machine

Weighted blankets are heavy, especially when wet. Overloading your washer can strain the machine and prevent the blanket from cleaning properly.

5. Using Hot Water

Hot water can cause shrinkage, fabric damage, or breakdown of the filling beads. Always use cold or lukewarm water.

6. Drying on High Heat

High dryer temperatures can melt or deform the weighted beads and shrink the fabric. Use low heat or air dry to preserve your blanket.

7. Skipping Spot Cleaning

Not treating stains early can make them harder to remove later. Spot clean stains promptly with mild detergent to avoid repeated full washes.

8. Neglecting to Fluff After Washing

Weighted blankets can develop clumps in the filling after washing. Fluff and shake the blanket thoroughly to redistribute the weight evenly.

Tips to Keep Your Blanket Clean Longer

Use a duvet cover
Don’t eat or drink in bed
Store in a dry place
Spot clean spills immediately
Air it out weekly to prevent odor buildup

Storage Tips

When not using your blanket:

Make sure it’s completely dry
Fold gently without compressing the filling
Store in a cotton or breathable bag (avoid plastic)
Keep in a cool, dry place
