Can Cooling Blankets Be Washed?

Cooling blankets have become popular for their ability to regulate body temperature and offer a more comfortable sleep environment. If you own one, a common question is whether these blankets can be washed and, if so, how to do it safely. The answer is yes—most cooling blankets can be washed—but the right method depends largely on the materials and technologies involved. Below, you’ll find practical guidance based both on manufacturers' recommendations and the properties of common fabrics.

1. Material Matters: Different Fabrics, Different Needs

Natural Fibers (Bamboo, Cotton, Linen)

• These blankets are generally straightforward to clean. They can usually be machine washed on a gentle cycle using cold water. This helps preserve their softness, breathability, and moisture-wicking qualities.
• Stick to a mild detergent, and avoid fabric softeners, as these can clog the fibers and interfere with the blanket’s cooling function.

Synthetics (Polyester, Microfiber, or Phase-Change/PCM/Gel-Infused Fabrics)

• Always check the care label. Some synthetic cooling blankets require hand washing or even spot cleaning, especially those containing phase-change materials or gel layers designed to regulate heat.
• Never use high heat, either in the wash or to dry, as that can degrade synthetic fibers and damage the cooling components.

Bamboo-Lyocell or Rayon

• Bamboo-based fibers need a bit of extra care. Use only the delicate cycle, as these fibers can become weak when wet. Avoid wringing or twisting to prevent damage.

2. Special Attention: Cooling Technologies

Phase-Change Materials (PCMs) or Gel Layers

• These materials absorb and release heat but can be sensitive to washing. Air drying is usually best, and you should always follow any special instructions provided by the manufacturer.

Electric Cooling Blankets

• Never submerge electrical components in water. Instead, wipe the surface clean with a damp cloth. For blankets with removable covers, only wash the cover according to its care label.

3. General Washing Guidelines

• Spot Cleaning: For minor stains, mix some mild detergent with water and gently spot clean.
• Machine Washing: Place the blanket in a mesh laundry bag to avoid snags, and use a gentle, cold water cycle.
• Drying: Air drying is safest—either hang the blanket or lay it flat to keep its shape. If you use a dryer, choose a low heat setting and remove the blanket while still slightly damp.

4. What to Avoid

• Avoid using bleach, harsh chemicals, or high dryer heat, as these can break down both natural fibers and synthetic cooling layers.
• Ironing is generally a bad idea, since heat can compromise moisture-wicking coatings and embedded cooling technologies.

5. Special Cases & Maintenance Tips

• Weighted Cooling Blankets: If the weight (beads or granules) is removable, take it out before washing. Otherwise, wash the entire blanket on a cold, gentle cycle and dry flat.
• Odor Issues: Pouring a half cup of white vinegar into the rinse cycle can help neutralize odors without harming the blanket.
• Storage: Store your cooling blanket in a cool, dry area to reduce the risk of mold and mildew.
• Extra Protection: Using a duvet cover helps minimize direct contact with sweat and oils, which means fewer washes for the blanket itself.
• Washing Frequency: To maintain hygiene and peak performance, aim to wash your cooling blanket every two or three weeks.

Conclusion

Most cooling blankets are washable, but the care you provide plays a big role in how long they remain effective. When in doubt, follow the manufacturer’s directions—especially for blankets with special cooling technologies. Natural fabrics like bamboo and cotton are the easiest to clean, while synthetics and electric models demand extra caution. With the right maintenance routine, your cooling blanket can continue keeping you cool and comfortable night after night.
