A weighted blanket is a game-changer for relaxation, stress relief, and better sleep. However, with regular use, it can accumulate dirt, sweat, pet hair, and spills, making proper cleaning essential. Washing a weighted blanket incorrectly can damage its structure, affect its weight distribution, or even ruin its fabric.
In this comprehensive guide, we’ll walk you through the best methods for washing a weighted blanket, whether by hand or machine, based on its fabric type and filling material.
Why Proper Cleaning of a Weighted Blanket Matters
Weighted blankets require special care because they contain unique materials, such as glass beads, plastic pellets, or cotton batting. Washing them improperly can lead to:
- Clumping or shifting of the weighted filling – This can ruin the even distribution of weight.
- Fabric damage – Some materials, like fleece or minky fabric, can degrade with improper washing.
- Loss of effectiveness – A dirty blanket may lose its breathability and softness.
By following the right washing techniques, you can extend the lifespan of your weighted blanket and keep it fresh.
How Often Should You Wash a Weighted Blanket?
Unlike regular blankets, weighted blankets don’t need frequent washing. Over-washing can wear down the fabric and filling.
Recommended Washing Frequency
- Once every 2 to 3 months – If you use it daily, wash your blanket every couple of months.
- More often for spills or stains – Spot-clean as needed to prevent stains from setting in.
- Use a duvet cover – If your blanket has a removable cover, wash the cover weekly to reduce how often you wash the weighted insert.
Understanding Your Weighted Blanket’s Care Label
Before washing your weighted blanket, check the care label for manufacturer instructions. The label provides essential details on:
- Machine washability – Some weighted blankets can be washed in a machine, while others require hand washing.
- Water temperature – Hot water can damage certain fabrics, so check for warm or cold water recommendations.
- Drying instructions – Some blankets can be tumble dried, while others require air drying.
Ignoring these instructions can lead to premature wear and tear.
Can You Machine Wash a Weighted Blanket?
General Machine Washing Guidelines
If your weighted blanket is under 15 pounds, you can typically wash it in a standard washing machine. For blankets over 15 pounds, a commercial-sized washer (such as those found in laundromats) is recommended to prevent damage.
- Use a gentle cycle – Prevents unnecessary stress on the fabric and stitching.
- Choose mild detergent – Harsh chemicals can break down the fibers over time.
- Avoid bleach and fabric softeners – Bleach can weaken the fabric, while fabric softeners can leave residue that affects breathability.
- Wash separately – This prevents extra weight from damaging the washing machine and ensures a thorough clean.
How to Wash a Weighted Blanket by Fabric Type
Different fabrics require different care methods. Here’s a breakdown of how to wash weighted blankets based on their material.
Cotton Weighted Blankets
Cotton is durable and easy to clean, but it can shrink if washed in hot water.
- Water temperature: Cold or warm
- Cycle type: Gentle or normal
- Drying: Tumble dry on low or air dry
Minky or Plush Weighted Blankets
Minky fabric is soft and cozy but can lose its texture if washed incorrectly.
- Water temperature: Cold
- Cycle type: Gentle
- Drying: Air dry or low-heat tumble dry
Fleece Weighted Blankets
Fleece is prone to pilling and static buildup, so extra care is needed.
- Water temperature: Cold
- Cycle type: Gentle with extra rinse
- Drying: Air dry or tumble dry on no heat
Linen Weighted Blankets
Linen is breathable and durable but should be handled with care to prevent wrinkling.
- Water temperature: Cold or lukewarm
- Cycle type: Gentle
- Drying: Air dry or tumble dry on low
Polyester Weighted Blankets
Polyester is resilient but can retain odors if not washed properly.
- Water temperature: Warm
- Cycle type: Normal
- Drying: Low heat tumble dry or air dry
How to Wash a Weighted Blanket Based on Filling Type
The type of weighted filling inside your blanket determines whether it can be machine washed or if it requires special care.
Glass Beads
Glass beads are durable and can typically be machine washed.
- Machine washable: Yes
- Drying: Air dry or low-heat tumble dry
Plastic Pellets
Plastic pellets can warp or melt under high heat, so they require extra caution.
- Machine washable: Yes (cold water)
- Drying: Air dry only
Sand or Organic Fillings
Sand and organic materials like rice or beans absorb water and clump, making machine washing unsuitable.
- Machine washable: No
- Cleaning method: Spot clean only
How to Hand Wash a Weighted Blanket
If your weighted blanket isn’t machine washable, hand washing is the best option.
Steps for Hand Washing
- Fill a bathtub or large basin with cold or lukewarm water.
- Add a mild detergent and mix it evenly in the water.
- Submerge the blanket and gently agitate it for a few minutes.
- Let it soak for 15–30 minutes to break down dirt and oils.
- Rinse thoroughly until no soap remains.
- Press out excess water without wringing or twisting the fabric.
- Lay flat to dry or hang over a sturdy drying rack.
Best Drying Methods for a Weighted Blanket
Drying your weighted blanket correctly ensures it maintains its structure and softness.
Air Drying
- Best for heavier blankets or those with delicate filling.
- Lay flat on a drying rack or spread evenly over a clothesline.
- Rotate the blanket every few hours to ensure even drying.
Machine Drying
- Use low heat or no heat to prevent shrinkage and damage.
- Place dryer balls or clean tennis balls in the dryer to fluff the blanket.
- Remove when slightly damp and let it air dry completely.
Avoid high heat settings, as they can damage fillings like plastic pellets or organic materials.
How to Keep a Weighted Blanket Clean Longer
Washing a weighted blanket frequently isn’t ideal, so taking preventive steps can help keep it fresh between washes.
Use a Duvet Cover
- A removable duvet cover is easier to wash and protects your blanket from spills and dirt.
- Wash the cover weekly or biweekly to keep your blanket clean.
Spot Clean Small Stains
- For small stains, use a damp cloth with mild soap instead of washing the entire blanket.
- Avoid harsh chemicals that can weaken fabric fibers.
Store Properly When Not in Use
- Store in a cool, dry place to prevent mold and mildew.
- Avoid plastic bags, as they trap moisture and can lead to odors.
Conclusion
Washing a weighted blanket correctly keeps it clean, fresh, and long-lasting. Whether machine washing, hand washing, or spot cleaning, always follow fabric and filling guidelines to avoid damage.
With proper care, your weighted blanket will remain cozy, comfortable, and in great condition for years to come.
