How to Wash a Weighted Blanket – Complete Guide

Weighted blankets have become a favorite for people seeking better sleep and relaxation. They provide comfort, reduce anxiety, and help improve sleep quality. But just like regular bedding, they eventually collect sweat, dirt, body oils, and accidental spills. That’s why it’s important to know how to wash a weighted blanket properly.

Unlike regular blankets, weighted blankets require special care because of their heavy filling materials like glass beads, plastic pellets, or steel beads. Washing them the wrong way can damage the fabric or filling, reducing their lifespan. In this guide, you’ll learn everything about how to wash a weighted blanket at home—from pre-treating stains to drying methods—so you can keep yours clean, fresh, and long-lasting.

Step 1: Check the Care Label

Before deciding whether to machine wash or hand wash, always check the manufacturer’s care instructions. Some blankets are designed to be machine washable weighted blankets, while others may require only handwashing or spot cleaning. Ignoring the label may lead to shrinking, tearing, or damage to the inner filling.

Step 2: Gather Cleaning Materials

To clean a weighted blanket safely, you’ll need a few essentials:

A washing machine (only if your blanket is machine-washable)
Mild liquid detergent (avoid bleach and strong chemicals)
Fabric softener (optional, for soft fabrics like fleece or cotton)
Stain remover for tough spots
A bathtub or basin (for hand washing a weighted blanket)

Using gentle cleaning agents is the best way to maintain the quality of both the fabric and the filling.

Step 3: Pre-Treat Stains

Stains are common on blankets, especially if you use them daily. Pre-treating helps ensure a deeper clean:

Oil or grease stains: Use a degreasing agent.
Food and beverage stains: Apply diluted white vinegar.
Blood stains: Dab carefully with hydrogen peroxide.

After applying the solution, scrub lightly with a soft brush or old toothbrush and let it sit for a few minutes before washing. This makes the final wash more effective.

Step 4: Washing Methods

Machine Wash Weighted Blanket

If your blanket is labeled as machine washable:

Place it evenly inside the washer drum.
Select a gentle or delicate cycle with cold or lukewarm water.
Add a small amount of mild detergent.
Start the wash, avoiding bleach or fabric softeners.

⚠️ Note: Since a weighted blanket can weigh 10–25 lbs, avoid overloading the washer to prevent motor strain.

Hand Wash Weighted Blanket

For blankets that cannot go in the washing machine:

Fill a bathtub with lukewarm water.
Add 1–2 ounces of mild detergent and mix well.
Submerge the blanket and let it soak for 30–45 minutes.
Gently agitate by hand to remove dirt.
Rinse thoroughly with clean water until soap is gone.
Squeeze out water carefully without twisting.

This method takes more effort but ensures the blanket stays safe from machine damage.

Step 5: Drying Your Weighted Blanket

Drying is just as important as washing. Here are the safe methods:

Air Dry (Recommended): Lay the blanket flat on a clean surface or drying rack to maintain shape and prevent stretching.
Tumble Dry (If Allowed): Use a low-heat or air-dry setting. Add dryer balls to keep the filling evenly distributed.

Never use high heat, as it can damage the filler materials or shrink delicate fabrics.

Step 6: How Often Should You Wash a Weighted Blanket?

The frequency depends on how you use it:

With a duvet cover: Every 2–3 months.
Without a cover (direct contact with skin): Every 3–4 weeks.
Spot cleaning: As needed for stains or spills.

A duvet cover not only protects the blanket but also reduces how often you’ll need a full wash.

Weighted Blanket Care by Filling Type

Different fillers need different washing methods. Here’s a quick guide:

Plastic pellets: Machine wash with cold water, air dry.
Steel beads: Machine wash or hand wash, then air dry.
Micro glass beads: Hand wash only, air dry.
Smooth pebbles: Hand wash and air dry.
Organic fillings (corn, beans, rice, sand): Not washable—spot clean only.

This ensures you don’t accidentally ruin the filling while trying to clean the blanket.

Final Tips for Longevity

Always use a duvet cover to protect the blanket.
Avoid bleach and strong detergents.
Never iron a weighted blanket.
Store it in a cool, dry place when not in use.

By following these steps, you’ll not only keep your blanket clean but also extend its lifespan.

Conclusion

Knowing how to wash a weighted blanket correctly makes all the difference in maintaining its comfort and durability. Whether you choose to machine wash a weighted blanket or hand wash it, following the right process ensures your blanket remains fresh, hygienic, and in good condition for years.

With proper care, your weighted blanket will continue to provide you with warmth, comfort, and better sleep—without the worry of dirt or germs building up.
