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

Mistakes to Avoid

Avoid these common cleaning errors:

• Using hot water (can damage fill or fabrics)
• Tossing in a regular top-loader with agitator
• Using bleach or strong detergents
• Wringing or twisting the blanket
• Skipping drying or letting it sit damp

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

Summary Checklist: Washing a Weighted Blanket

• Check the care label
• Identify fabric and filling type
• Remove duvet cover if present
• Spot clean any stains
• Use front-loader for machine wash (gentle cycle, cold water)
• Use large towels if hand washing
• Air dry flat or tumble on low (if safe)
• Fluff and redistribute filling
• Wash every few months (more if uncovered)

Final Thoughts

Weighted blankets are an investment in comfort and mental well-being. But they need proper care to stay effective, clean, and hygienic.

Washing one isn’t difficult — it just requires a little planning. With the right tools, detergent, and care steps, you can safely clean your blanket at home or take it to a laundromat when needed. Keeping it fresh not only extends its life but also ensures it keeps doing what it does best: helping you rest easy.

So check that label, follow these steps, and enjoy your clean, cozy blanket with peace of mind.
