How to wash a weighted blanket. Weighted blankets are amazing for reducing anxiety and improving sleep — but they’re also heavy, bulky, and expensive. So when it’s time to clean yours, you definitely don’t want to mess it up.
In this guide, we’ll show you how to safely wash and care for your weighted blanket, whether it’s filled with glass beads, poly pellets, or made of chunky knit cotton.
Can You Wash a Weighted Blanket?
Yes — but it depends on the material and weight.
Some weighted blankets are fully machine-washable, while others require spot-cleaning or dry cleaning. Always check the manufacturer’s tag first. Washing a blanket that’s not designed for it can damage the fabric, the fill, or your washing machine.
What to Check First
Before tossing your blanket in the wash, answer these questions:
- Does it have a removable cover?
If yes, wash the cover separately and only wash the inner blanket as needed. - What’s the fill made of?
Most are either glass beads (more durable and washable) or plastic poly pellets (may warp in high heat). - What fabric is it made from?
Cotton and bamboo are generally safe for machine washing. Wool, fleece, or minky materials may require special care. - What’s the total weight?
Most home washers can handle blankets up to 15–20 lbs. Heavier ones may need a commercial washer.
How to wash a weighted blanket (Step-by-Step)
1. Remove the cover (if possible)
Many brands like Hush and Gravity have duvet-style covers. These are usually machine washable.
2. Check care label
Follow the brand’s specific instructions for temperature, detergents, and drying.
3. Use cold or warm water
Hot water can shrink the fabric or damage the weighted fill. Stick to cold or warm settings.
4. Mild detergent only
Avoid bleach, fabric softener, or harsh chemicals.
5. Gentle or delicate cycle
This reduces stress on the seams and fill.
How to Dry a Weighted Blanket
Air Drying (Best Option)
- Lay it flat on a clean surface or drying rack
- Flip it every few hours to prevent clumping
- Avoid hanging it — the weight can distort the shape
Tumble Dry (If Tag Allows)
- Use low heat
- Add dryer balls to help fluff it evenly
- Never use high heat — it can melt poly pellets or shrink fabric
Spot Cleaning Tips
For small stains:
- Mix a little mild detergent with warm water
- Use a clean cloth or sponge to dab the area
- Blot dry with a towel
Avoid rubbing, which can spread the stain or damage fabric.
How Often Should You Wash It?
- Duvet cover: Every 1–2 weeks (like sheets)
- Weighted insert: Every 1–2 months, or as needed
- No cover? Spot clean often and machine wash every 4–6 weeks
What NOT to Do
- Don’t use bleach or harsh stain removers
- Don’t wring out or twist the blanket
- Don’t iron it
- Don’t dry clean unless the tag says it’s safe
Final Tips: Keep It Fresh Longer
- Use a removable cover to protect the inner blanket
- Air out the blanket every few days
- Store it flat or folded in a dry, clean space
