by Short answer: Most weighted blankets can be washed at home in a front-loading machine if it has enough capacity (at least 5 cubic feet for blankets up to 15 lbs). Use cold or warm water on a gentle cycle, mild detergent, and tumble dry on low heat. The biggest risk is overloading your machine, which can damage the motor and leave the blanket unevenly cleaned. For blankets over 15 lbs, go to a laundromat.
Before You Wash: What You Need to Know
Check the care label. Every weighted blanket is different. Some are dry-clean only. Most modern weighted blankets are machine washable, but the care label is the authority, not general advice.
Know your blanket weight. This is the most important factor. A 25 lb weighted blanket needs a commercial washer. A 12 lb blanket fits in most front-load home washers with 5+ cu ft capacity.
Know your fill type:
- Glass microbeads: Heat-stable. Fine in warm water and low dryer heat.
- Plastic poly pellets: Can warp at high heat. Cold water wash, low heat or air dry only.
- Steel shot beads: Heavy and heat-stable. Same care as glass.
Step-by-Step: How to Machine Wash a Weighted Blanket
- Check the weight. Up to 15 lbs: home front-load washer. 15-25 lbs: commercial laundromat. Over 25 lbs: commercial washer or professional cleaning.
- Inspect for damage. Check all seams and stitching. Any tears will worsen under washing and could cause fill to escape into your machine.
- Remove the cover (if applicable). Wash the cover separately as a regular item.
- Load alone. Do not add other laundry. The blanket needs room to move for even cleaning and rinsing.
- Use mild detergent. 1-2 tablespoons of liquid detergent, gentle formula. Avoid bleach and fabric softener, which can damage stitching and fill distribution over time.
- Select cold or warm water, gentle cycle. Do not use hot water. Spin on low speed to reduce stress on seams.
- Run an extra rinse cycle. Detergent trapped in the fill can cause skin irritation and stiffness.
- Check the blanket before drying. Feel all sections for even fill distribution. Redistribute any clumped areas by hand.
Step-by-Step: How to Dry a Weighted Blanket
- Option A (dryer): Low heat only. Add two dryer balls to help distribute the fill. Run 30-40 minute cycles and check between each. Weighted blankets take longer to dry than regular blankets due to their density.
- Option B (air dry): Lay flat on a clean surface or hang over two drying racks to distribute weight evenly. Do not hang from one point, which can stretch stitching. Allow 4-8 hours depending on size and fill density.
- Check for complete dryness. Press firmly into all corners and thick sections. Damp fill in an enclosed blanket will develop mildew within 24-48 hours.
Can You Spot Clean Instead of Washing?
Yes, for minor stains. Mix a small amount of mild dish soap with cold water. Apply with a clean cloth, blot the stain (do not rub), and rinse by blotting with a clean damp cloth. Air dry the spot thoroughly. This extends the time between full washes.
Washer Capacity Guide
| Blanket Weight | Minimum Washer Capacity | Recommendation |
|---|---|---|
| Under 10 lbs | 3.5 cu ft | Standard home washer OK |
| 10-15 lbs | 5 cu ft | Large home washer, front-load preferred |
| 15-20 lbs | 6 cu ft or commercial | Laundromat recommended |
| Over 20 lbs | Commercial only | Laundromat or professional cleaning |
Frequently Asked Questions
Can you put a weighted blanket in a regular washing machine?
It depends on the blanket's weight and your machine's capacity. A standard home washer can handle a weighted blanket up to 15 lbs if the machine has at least 5 cubic feet of capacity and a front-loading drum. For blankets over 15 lbs, a commercial laundromat machine (20 lb capacity or more) is recommended to avoid motor damage.
How often should you wash a weighted blanket?
Wash your weighted blanket every 2 to 4 weeks if used nightly without a duvet cover. If used with a removable cover that you wash weekly, the blanket itself needs washing only every 1 to 2 months. Spot clean spills immediately to reduce full washes.
What temperature should you wash a weighted blanket?
Use cold or lukewarm water (30C/86F maximum) for most weighted blankets. Hot water can damage the stitching, cause cotton to shrink, and in rare cases affect glass bead distribution. Check your care label, but when in doubt, cold water is safe for all fill types.
Can you put a weighted blanket in the dryer?
Many weighted blankets are dryer safe on low heat. Avoid high heat, which can melt plastic pellet fill or damage the outer fabric. Dry in multiple shorter cycles (30-40 minutes each), checking that beads redistribute evenly and no damp spots remain in the corners. Air drying is always the safest option.
How do you wash a weighted blanket with glass beads vs plastic pellets?
Both glass bead and plastic pellet weighted blankets can be machine washed on a gentle cycle in cold or warm water. Glass beads are heat-stable and unaffected by dryer use. Plastic pellets can warp at high temperatures, so use low heat or air dry only. Both types should be washed in a machine with enough capacity to allow the blanket to move freely.
