How to Clean a Weighted Blanket: A Complete Guide to Keeping It Fresh and Long-Lasting

Weighted blankets have gained widespread popularity for their soothing, calming effect—helping reduce anxiety, improve sleep quality, and support relaxation. But like any soft, weighted comfort item, your blanket needs regular cleaning to stay fresh, hygienic, and effective. In this guide, we’ll walk you through the best practices for cleaning your weighted blanket, ensuring it remains safe, clean, and comfortable for years to come.


Understanding the Context

Why Cleaning Your Weighted Blanket Is Important

Over time, weighted blankets collect sweat, oils, dust, dust mites, and other bacteria. Without proper cleaning, these deposits can lead to unpleasant odors, skin irritations, and potential mold or mildew—especially if moisture gets trapped. Regular maintenance not only preserves the integrity of the fabric and weight pellets but also extends the life of your blanket, keeping it safe for sensitive skin and therapeutic use.

Key Insights

Step 1: Check the Care Label

Always start by checking the manufacturer’s care instructions. While most weighted blankets are machine washable, some may require special handling due to fabric type or weight.

Step 2: Spot Clean Small Stains Immediately

For fresh spills or stains (like food, lotion, or sweat), treat them right away using a mild, fragrance-free cleaner. Blot (don’t rub) the area with a clean cloth dampened with water and a drop of gentle dish soap or laundry detergent. Avoid harsh chemicals or bleach—these can damage the fabric and embroidered weights.

Step 3: Machine Wash (When Appropriate)

Most weighted blankets are machine washable on a cold or warm delicate cycle. Use mild, hypoallergenic detergent designed for sensitive skin to prevent irritation. Avoid fabric softeners, which can weigh down the filling and reduce the blanket’s therapeutic effectiveness.

Step 4: Select the Right Wash Settings

  • Temperature: Stick to cold or warm (max 104°F / 40°C) to preserve fabric and prevent melting of weight pellets.
  • Cycle Type: Use a gentle or delicate cycle to minimize friction and maintain integrity of the weighted fill.
  • Detergent: Choose a fragrance-free, hypoallergenic detergent to reduce skin irritation and ensure safety for all users.

Step 5: Air Dry Only

Never use a dryer—heat can damage both the fabric and internal weights. Lay the blanket flat on a clean towel or hang it to air dry completely. Avoid direct sunlight for extended periods, as UV rays may fade colors over time.

Final Thoughts

Step 6: Re-Restock or Replace Weights (If Needed)

After cleaning, inspect your weighted fill. If the weight has shifted or some pellets have fallen out, gently re-insert them according to the manufacturer’s instructions. Some blankets feature removable weights; check if yours allows for easy refilling.


Frequently Asked Questions

Can I machine dry a weighted blanket?
Most are air-dry only—check your label. If machine drying is approved, use low heat and remove immediately once dry.

How often should I clean my weighted blanket?
Wash every 1–2 months or immediately after major stains. Regular spot cleaning after use helps maintain freshness.

What detergent should I use?
Opt for fragrance-free, hypoallergenic laundry detergents with no harsh additives.

Can I put bleach in my weighted blanket?
No—bleach damages fabric, weakening the blanket’s structure and compromising safety.


Pro Tips for Maximum Longevity

  • Use a breathable cover: If your blanket has a removable, breathable top layer, wash that separately for better airflow.
  • Rotate the blanket: If possible, rotate while using it to prevent uneven weight distribution and fabric wear.
  • Inspect weights regularly: Check for looseness or damage and re-secure weights promptly.
