Is It Possible to Wash Cooling Blankets? An All-Inclusive Handbook for Maintenance and Cleaning

For those who struggle with overheating, cooling blankets have become a popular solution. These blankets, designed to regulate body temperature, incorporate specialized materials such as phase-change technology, moisture-wicking fabrics, and breathable textiles. Like any other bedding, cooling blankets require regular cleaning to maintain hygiene and functionality. While there are important factors to consider, the answer is yes—you can wash a cooling blanket. This comprehensive guide will walk you through the correct way to wash and care for cooling blankets without compromising their unique properties.

Understanding Cooling Blanket Materials

Before tossing your cooling blanket into the wash, it’s essential to understand the materials used in its construction, as different fabrics and technologies require specific care methods. Here are some common types of cooling blankets:

  • Bamboo-derived fabric – Naturally breathable, hypoallergenic, and moisture-wicking.
  • Cotton blends – Soft and airy, though improper washing may cause shrinkage.
  • Microfiber or polyester blends – Lightweight and moisture-wicking but prone to static cling.
  • Phase-change material (PCM) – Absorbs and releases heat but may be sensitive to harsh detergents and high heat.
  • Gel-infused layers – Often found in weighted cooling blankets, these require special care to prevent damage.

Always check the manufacturer’s label for the best washing instructions tailored to your specific blanket.

Can You Machine Wash Cooling Blankets?

Most cooling blankets are machine washable, but their materials and construction determine the proper approach. Follow these steps to safely clean your blanket in a washing machine:

Step 1: Review the Care Label

The first step is to carefully read the care label for specific washing instructions. Some cooling blankets may only be suitable for hand washing, while others require cold water cycles.

Step 2: Use a Gentle Cycle

If machine washing is allowed, select a gentle cycle to minimize wear and tear. High-speed agitation can damage delicate fibers or disrupt the cooling technology embedded in the fabric.

Step 3: Use Mild Detergent

Avoid harsh detergents, bleach, and fabric softeners, as these can compromise the blanket’s cooling properties. A mild, eco-friendly detergent is the best choice.

Step 4: Wash with Cold Water

Cold water helps preserve the blanket’s cooling properties and prevents shrinkage. Hot water can weaken the fabric and reduce its effectiveness.

Step 5: Avoid Overloading the Machine

Washing a cooling blanket with too many other items can result in inadequate cleaning and excessive wear. If your blanket is large, consider washing it separately.

How to Hand Wash a Cooling Blanket

If your cooling blanket is not machine washable or if you prefer extra care, hand washing is a great alternative. Follow these steps:

  1. Fill a Tub with Cold Water – Use a bathtub or a large basin with enough space to submerge the blanket fully.
  2. Add Mild Detergent – Mix a small amount of mild detergent into the water.
  3. Submerge and Gently Agitate – Soak the blanket and gently swish it around. Avoid vigorous scrubbing or wringing, as this can damage delicate fibers.
  4. Rinse Thoroughly – Drain the soapy water and refill with fresh cold water to remove detergent residue.
  5. Press Out Excess Water – Without twisting or wringing, gently press the blanket to remove excess water.
  6. Air Dry Properly – Either hang the blanket on a drying rack away from direct sunlight or lay it flat on a clean, dry surface.

How to Properly Dry a Cooling Blanket

Proper drying is just as important as washing to maintain the integrity of a cooling blanket. Follow these key guidelines:

  • Air drying is best – Hang the blanket on a drying rack in a well-ventilated area or lay it flat on a clean surface.
  • Avoid direct sunlight – Prolonged sun exposure can weaken fabric fibers and cause fading.
  • Tumble dry on low heat if allowed – Some blankets permit low-heat drying in a machine. Always check the care label first.
  • Fluff the blanket occasionally – If air drying, shake or fluff the blanket periodically to ensure even drying and prevent stiffness.

Special Considerations for Weighted Cooling Blankets

Weighted cooling blankets often contain glass beads or other filler materials that require additional care. Here’s how to maintain them:

  • Many weighted cooling blankets come with a removable cover that can be washed separately.
  • If the inner weighted blanket is not machine washable, spot clean with a damp cloth and mild detergent.
  • If machine washing is allowed, use a gentle cycle and a high-capacity washer to prevent damage.
  • Always lay flat to dry – Hanging a weighted blanket can cause the filler material to shift unevenly.

Maintaining Your Cooling Blanket Between Washes

To extend the lifespan of your cooling blanket and reduce the need for frequent washing:

  • Use a duvet cover or protector – A removable cover is easier to clean and helps keep the blanket fresh.
  • Spot clean stains immediately – Use a soft cloth and mild detergent to address spills and stains promptly.
  • Air out the blanket regularly – Hanging it in a well-ventilated space between washes helps maintain freshness.
  • Store it properly – When not in use, keep your blanket in a breathable storage bag in a cool, dry place to prevent dust and moisture buildup.

Do Cooling Blankets Go in the Washer? Dos and Don’ts

Cooling blankets are designed to regulate body temperature and provide relief for hot sleepers, but they also require proper care to maintain their effectiveness. One common question is whether these blankets can be safely washed in a washing machine. The answer depends on the material and manufacturer instructions. Here’s a detailed breakdown of what you should and shouldn’t do when washing a cooling blanket.


Yes, Many Cooling Blankets Are Washer-Friendly

Most cooling blankets made from materials like cotton, bamboo, microfiber, or nylon can be washed in a machine. However, it’s essential to read the product’s care label, as some brands have specific instructions based on the cooling fabric technology used.


Dos: How to Properly Wash a Cooling Blanket

Check the Care Label First

Always read the care instructions on the blanket’s tag. This will tell you whether machine washing is safe and specify the best washing settings.

Use a Gentle Cycle

Select a delicate or gentle cycle on your washing machine. This reduces the chance of wear and tear on the fabric and helps preserve the cooling features.

While many cooling blankets are designed to be low maintenance, proper washing techniques are essential to ensure longevity and sustained performance. Following the right cleaning routine can help your cooling blanket stay fresh, effective, and comfortable for years to come.

Why Your Cooling Blanket Smells: Is It Time to Wash It?

Cooling blankets are a lifesaver for hot sleepers, offering breathable fabrics and temperature-regulating properties that promote better rest. However, over time, you may notice an unpleasant smell coming from your blanket. This is more common than you might think—and it’s a clear sign that your cooling blanket needs attention.

In this article, we’ll explain why your cooling blanket might smell and how to know when it’s time to wash it.


Common Reasons Why Your Cooling Blanket Smells

1. Sweat and Body Oils Build-Up

Even though cooling blankets are designed to wick away moisture, they still absorb sweat, body oils, and skin cells. Over time, these substances accumulate and can create a sour or musty odor.

2. Lack of Regular Washing

Unlike regular blankets, cooling blankets often have special fabrics that feel dry and fresh longer—but that doesn’t mean they don’t need washing. Infrequent cleaning allows bacteria and odors to build up.

3. Humidity and Poor Storage

If you live in a humid area or store your blanket without properly drying it, mildew and mold can form. This leads to a damp, musty smell that’s difficult to ignore.

4. Fabric Type and Air Circulation

Synthetic cooling materials can sometimes trap odor molecules more than natural fabrics like cotton or bamboo. If the blanket doesn’t get enough air circulation—especially after use—it can start to smell.


Is It Time to Wash Your Cooling Blanket?

Here are some signs that indicate it’s time to clean your cooling blanket:

  • You notice a lingering smell, even after airing it out.
  • The fabric feels sticky or oily, especially in high-contact areas.
  • The blanket looks dull or stained, particularly around the neck, chest, or foot area.
  • You haven’t washed it in over a month, especially if used regularly.

In most cases, washing your cooling blanket once every 2 to 4 weeks is ideal, depending on how frequently you use it.
