You want to keep your bed fresh and comfortable, and that means knowing how to wash a cooling pillow. It’s not as hard as you might think, but doing it wrong can damage the special materials. This guide will walk you through the entire process, step by step, so your pillow stays cool and supportive for years to come.
Cooling pillows are a game-changer for hot sleepers. They use materials like gel-infused memory foam, phase-change fabrics, or breathable gels to draw heat away from your head. But these materials need specific care. Throwing it in the wash without checking could ruin its cooling properties and shape.
Don’t worry, though. With the right information, washing your cooling pillow is a simple task. We’ll cover how to read the care label, the different methods for different types, and how to dry it properly. Let’s get started.
How To Wash A Cooling Pillow
Before you do anything, find the care label. This is the most important step. The manufacturer’s instructions are your best guide. The label will tell you if your pillow is machine washable, spot clean only, or has other specific needs. If the tag is missing, you can usually find the care instructions online by searching your pillow’s brand and model.
Step 1: Check the Care Label
Look for symbols or text on the tag sewn into the pillow seam. Common instructions include:
- “Machine Wash Gentle” or “Machine Wash Cold”
- “Do Not Machine Wash” or “Spot Clean Only”
- “Tumble Dry Low” or “Air Dry Flat”
- “Do Not Bleach” (almost always the case for cooling pillows)
If it says “Do Not Wash,” you should only spot clean it. Never ignore this warning.
Step 2: Prep Your Pillow for Washing
Even if it’s machine washable, a little prep makes a big difference. First, remove any removable covers. These are usually washable separately. Check the pillow itself for stains and pretreat them with a mild detergent or a stain remover that’s safe for delicate fabrics. Gently rub it in and let it sit for 10-15 minutes before washing.
Step 3: Choose Your Washing Method
The method totally depends on your pillow type. Here’s a breakdown for the most common cooling pillow materials.
For Gel-Infused Memory Foam or Shredded Foam Pillows
These are almost never machine washable. The foam can break down and clump in the wash. The correct method is spot cleaning.
- Mix a small amount of mild detergent with cool water.
- Dampen a clean, white cloth (to avoid dye transfer) in the solution and wring it out well.
- Gently blot the stained area. Never rub, as this can push dirt deeper or damage the fabric.
- Use a second cloth dampened with clean water to rinse the area by blotting.
- Press a dry towel against the spot to absorb as much moisture as possible.
For Pillows with Phase-Change Material (PCM) Covers
Often, the cooling magic is in the cover, not the inner pillow. Usually, the cover is zippered and machine washable, while the inner insert needs spot cleaning or airing out. Always seperate them and follow each piece’s care label.
For Gel-Fiber or Polyester Cooling Pillows
Many of these are safe for the washing machine. Always use a gentle cycle with cold water. Hot water can damage the cooling fibers and cause clumping. Use a mild detergent and avoid fabric softener, as it can coat the fibers and reduce their breathability and cooling effect.
Step 4: Drying Your Cooling Pillow Thoroughly
This step is crucial. A damp pillow can grow mold and mildew inside. Never put a cooling pillow in the dryer unless the label explicitly says you can.
- Air Drying is Best: Lay the pillow flat on a clean, dry towel or a drying rack. Flip it every few hours to ensure even drying. This can take 24-48 hours. Make sure it’s in a well-ventilated area.
- If Tumble Dry is Allowed: Use the lowest heat setting possible. Toss in a couple of dryer balls or clean tennis balls to help break up clumps and fluff the filling. Check it every 20 minutes.
No matter the method, ensure the pillow is completely, 100% dry before putting a cover on it and using it again. Any leftover moisture is a problem waiting to happen.
How Often Should You Wash a Cooling Pillow?
You should wash your cooling pillow every 3-6 months. A good rule is to do it when you change your bedding for the season. Always wash the protective cover weekly or bi-weekly, as this catches most of the oils, sweat, and dirt. This practice will keep your main pillow cleaner for longer and reduce how often you need to deep clean it.
Common Mistakes to Avoid
Making a mistake can shorten your pillow’s life. Here’s what to steer clear of.
Using Hot Water or High Heat
Heat is the enemy of cooling materials. It can melt glues, break down foam, and ruin phase-change substances. Always stick to cold washes and air drying or the lowest dryer setting.
Using Harsh Chemicals or Bleach
Bleach and strong detergents will degrade the special fabrics and foams. They can also strip away the cooling treatment applied to the fibers. Stick to mild, gentle detergents.
Over-Wetting the Pillow
When spot cleaning, use a well-wrung cloth. You want to dampen the surface, not soak the interior. Too much water is very difficult to dry out of a dense pillow.
Putting a Foam Pillow in the Washer
This bears repeating. Memory foam acts like a sponge. It will absorb water, become incredibly heavy, and likely tear apart inside the machine. The foam also rarely dries properly, leading to mold. Always spot clean foam pillows.
Tips for Maintaining Your Pillow Between Washes
Regular maintenance makes the big washes easier and keeps your pillow feeling fresh.
- Use a Protectant: Always use a zippered pillow protector under your regular pillowcase. It acts as a shield against sweat, oils, and dust mites. Choose a protector made from breathable, cooling material so it doesn’t block the pillow’s function.
- Air it Out: Once a week, when you change your sheets, let your pillow air out for an hour or two without any cover on it. This helps moisture evaporate and freshens it up.
- Fluff Daily: Give your pillow a good fluff and shake every morning. This helps maintain its loft and allows air to circulate through the filling.
- Vacuum Occasionally: Use the upholstery attachment on your vacuum to gently go over the pillow surface. This removes dust and skin particles that accumulate over time.
FAQ Section
Can you put a cooling pillow in the washing machine?
It depends entirely on the care label. Gel-fiber or polyester cooling pillows often can be washed on a gentle, cold cycle. However, memory foam or gel-infused foam pillows should never go in the washing machine. Always check the tag first.
How do you wash a cooling gel pillow?
For a gel pillow with a solid foam core, spot cleaning is the only safe method. For a pillow filled with gel-infused fibers or beads, it may be machine washable. The key is to identify the inner material and follow those specific instructions to preserve the cooling gel.
What is the best way to dry a cooling pillow?
Air drying flat is almost always the safest and best method. It prevents heat damage and ensures the core dries completely. If the label permits machine drying, use the lowest heat setting and include dryer balls to prevent clumping.
Can I use vinegar to wash my cooling pillow?
A small amount of white vinegar in the rinse cycle can act as a natural fabric softener and deodorizer for machine-washable pillows. However, never use it on foam pillows, and always do a spot test first to ensure it doesn’t discolor the fabric. Avoid using it too frequently.
Why does my cooling pillow smell after washing?
A lingering smell usually means the pillow is not completely dry. Moisture trapped inside can cause a musty odor or even mildew. Ensure you are using the proper drying method and give it plenty of time—sometimes up to 48-72 hours for thick pillows—to dry all the way through.
How long does a cooling pillow typically last?
With proper care, a good quality cooling pillow should last between 2 to 3 years. Over time, the materials will naturally lose some of their resilience and cooling properties. Regular washing according to instructions helps maximize its lifespan.
When It’s Time for a Replacement
Even with perfect care, pillows don’t last forever. Here are signs your cooling pillow needs to be replaced:
- It stays flat and won’t fluff back up, losing its support.
- You notice visible stains or odors that won’t come out after a proper cleaning.
- The cooling sensation is no longer noticeable.
- The filling is lumpy or shifting unevenly.
- It’s been more than 3 years since you bought it, and your sleep quality has declined.
Knowing how to wash a cooling pillow correctly is the best way to protect your investment and ensure you get the restful, cool sleep you paid for. By following the care label, avoiding heat, and being patient with the drying process, you’ll extend your pillow’s life significantly. Start by checking that tag, and give your pillow the care it deserves.
