How to Properly Wash a Cooling Blanket

Cooling blankets have become increasingly popular as a comfortable way to stay cool on warm nights without relying on air conditioning. These blankets use advanced cooling fibers or technologies to regulate body temperature and wick away moisture, enhancing your sleep quality. 

However, proper washing is essential to maintain their performance, as incorrect cleaning can damage the delicate cooling fibers. This guide will provide all the information you need to wash your cooling blanket correctly, from understanding the materials to step-by-step washing instructions and tips for keeping it fresh between washes.

Understanding Cooling Blanket Materials

Not all cooling blankets are the same. These high-tech blankets use engineered materials for optimal cooling and moisture-wicking. To avoid degrading these materials, understand your blanket’s composition. Common materials include:

1. Bamboo: Eco-friendly and breathable, bamboo fibers pull heat away and are moisture-wicking and odor-resistant. However, bamboo can shrink, so wash in cold water.
2. Tencel: Soft and absorbent, Tencel (lyocell) is cool, breathable, and anti-bacterial. Wash in cold to lukewarm water.
3. Performance polyester: Engineered for breathability and quick drying, this durable fabric is used in athletic wear and cooling bedding but can retain odors, so wash frequently.
4. Cotton blends: These combine cotton with cooling fibers for softness and temperature regulation. Care depends on the specific fiber mix.

Always check the care label, as each material has specific washing requirements, including possible special detergents or hand washing.

Pre-Wash Preparation

Before washing your cooling blanket, follow these steps:

1. Read the care label: Check for specific washing instructions and restrictions. If it says "dry clean only," avoid washing it at home to prevent damage.
2. Shake out the blanket: Take it outside and shake off loose debris like crumbs and pet hair to prevent abrasion during washing.
3. Spot-clean stains: Identify and treat any stains with a suitable stain remover. Test on a small area first, apply gently, and let sit for 15 minutes before washing.
4. Wash separately: Clean cooling blankets alone or with similar lightweight items to avoid snagging, abrasion, or linting from heavier fabrics or zippers.

Machine Washing a Cooling Blanket

If your cooling blanket's care label gives the green light for machine washing, follow these steps for optimal results:

Use a gentle cycle with cold water: Choose the delicate cycle and the coldest water setting to avoid damage and shrinkage.

Add a mild detergent: Use a liquid detergent for delicates, avoiding bleach, fabric softeners, and harsh additives. Use the minimal amount needed to prevent residue buildup.

Wash separately or with like fabrics: Wash the blanket alone or with other lightweight, delicate items in similar colors to avoid damage.

Don't overload the washer: Ensure the blanket has space to move freely to prevent abrasion. Use a commercial-sized washer for large or heavy blankets.

Double rinse: Run an extra rinse cycle to remove all detergent and maintain the blanket’s cooling effectiveness.

Hand Washing a Cooling Blanket

Some delicate cooling blankets, especially those with special features like weighted beads or intricate stitching, may require hand washing. Here's how to hand wash a cooling blanket safely:

Fill a clean sink or bathtub with cool water and add a small amount of mild detergent formulated for delicates. Use the amount specified on the detergent bottle for a small load.

Immerse the blanket fully in the soapy water and gently agitate it with your hands to work the soap through the fibers. Don't twist, wring, or scrub the blanket, which can damage the fibers and cooling technology.

Let the blanket soak in the soapy water for 15-20 minutes. This allows the detergent time to break down any oils, sweat, or dirt trapped in the fibers.

Drain the soapy water from the sink or tub and refill with clean, cool water. Press the blanket gently to release the suds and rinse the fibers. Repeat the rinse process, draining and refilling with fresh water, until the water runs clear and you can't feel any soapy residue in the fabric.

Gently squeeze out the excess water, being careful not to twist or wring the blanket. You can also roll it in a clean, dry towel to absorb the water.

Drying a Cooling Blanket

Proper drying is just as critical as proper washing when it comes to maintaining your cooling blanket's performance and longevity. Follow these best practices for drying:

Air dry whenever possible: The gentlest and safest method for drying a cooling blanket is to hang it or lay it flat to air dry. Hang it over a clean shower rod, large drying rack, or clothesline, or lay it on a clean, dry surface like a bed or carpet. Keep it out of direct sunlight and away from heat sources like radiators or vents, as high heat can damage the cooling fibers.

If using a dryer, use low heat and remove promptly: Sometimes air drying isn't practical, especially for large or heavy cooling blankets. If you need to use a machine dryer, select the lowest heat setting possible. Remove the blanket from the dryer while it's still slightly damp, then hang or lay it flat to finish air drying. Never use medium or high heat, as this can cause irreversible damage to the cooling fabric.

Add dryer balls: Toss a few wool dryer balls in with your cooling blanket. They'll help fluff the fibers and speed up drying time without the need for fabric softeners or dryer sheets, which can leave a coating that clogs the breathable weave.

Avoid fabric softeners and dryer sheets: As mentioned above, both liquid fabric softeners and dryer sheets leave behind a waxy residue that can build up on the fibers of your cooling blanket, reducing its breathability and moisture-wicking abilities. Skip them entirely when washing and drying your blanket.

Caring for Your Cooling Blanket Between Washes

Washing your cooling blanket too frequently can put unnecessary wear and tear on the delicate fibers. With proper care between washes, you can keep your blanket fresher longer and reduce how often you need to do a full wash. Here are some tips:

Spot clean small stains immediately: Spills and stains are inevitable, but addressing them quickly prevents them from setting. Immediately blot the area with a clean, damp cloth and a small amount of mild detergent. Avoid rubbing, as it can spread the stain. Blot gently until the stain is gone, then use a clean, damp cloth to remove any leftover detergent.

Shake and air out regularly: In between uses, give your cooling blanket a good shake outside to remove any loose debris, pet hair, or crumbs. Then, hang it in a well-ventilated area, like over a clothesline or on a large drying rack, for a few hours to air out. This will help release any trapped odors, moisture, or body oils and keep the blanket smelling fresh.

Store properly: When not in use, store your cooling blanket in a cool, dry place away from sunlight and heat. Fold loosely or roll to avoid deep creases. Use a breathable cotton bag or wrap it in a clean, dry sheet, not a plastic container, to prevent mildew.

Conclusion

In conclusion, Proper washing and care are key to keeping your cooling blanket at its best. Always follow the care label: wash in cold water on a gentle cycle with mild detergent, and air dry or use the lowest heat setting if drying.

Regular shaking, airing out, and spot cleaning maintain freshness between washes. Store in a cool, dry place, away from heat and sunlight, using a breathable fabric bag.

Following these guidelines will keep your blanket fresh, clean, and effective, extending its lifespan and ensuring cool comfort for years.
