How to Wash Your Pillow (Yes, You Should)
Consumer Reports has no financial relationship with advertisers on this site.
While you’re probably in the habit of regularly washing your sheets and pillowcases, you might not give as much attention to what lies beneath: your pillows and mattress. But both need a good cleaning: twice a year for your mattress, once each season for your pillow.
“Over time, hair, dead skin cells, sweat, and drool build up on the pillow,” says Neil Kao, MD, an allergist-immunologist in Greenville, S.C. And all that gunk is basically the stuff that dust mites love to munch on, causes their population to multiply, and increases the chance for an allergic reaction to their presence.
If you watched Consumer Reports’ video on how to clean a mattress, we trust that you’ve added that to your rotation of household chores. Adding a pillow to the cleaning list should be a breeze by comparison.
You might also want to invest in a pillow protector to keep a lot of the gross stuff out and extend the life of your pillow.
Here, Consumer Reports shows you how to keep your pillow fresh, clean, and ready for a good night’s sleep. And if it’s time for a new pillow altogether, check out our pillow buying guide or head over to our pillow ratings to see which ones are up to fluff.
Just one thing before you clean: When washing pillows, always read the label first. Many pillows—though not all—can be machine washed.
Step 1: Air It Out
Give your pillows a daily fluffing to restore their shape and remove dust. Then, every month or so, hang them outdoors on a clothesline for a few hours, ideally on a bright, breezy day. If that’s not an option, as with some foam and latex pillows, run them through the dryer on the no-heat cycle.
Step 2: Wash It Gently
Laundering a pillow isn’t difficult, though it can take a bit of time to dry.
If your pillow has a wet stain that you’re trying to remove, immediately spot treat the pillowcase and pillow with a stain cleaner that targets that type of stain before popping it into the wash.
If your washing machine is large enough, wash two pillows at a time. That will help balance the load, allowing the water and detergent to circulate more effectively. The agitator on conventional top-loaders can be tough on pillows, so it’s best to agitate on the gentle cycle only for a few minutes (or the shortest possible setting, if you can’t control the time). Alternatively, you could make a special trip to the laundromat to use its front-loaders.
Follow these directions for specific types of pillow fills.
Down or feather: Most down pillows can be put in the washing machine, but use cool water and a mild detergent, then dry on low heat. (High temperatures can damage the down.)
Memory foam or latex: Washer agitation can break up foam, so these pillows will probably need to be hand washed. Vacuum dust off of the pillow, then spot clean with a clean, damp cloth and a small amount of mild detergent. Then lay the pillow flat to air dry.
Polyester: Wash with warm water on the gentle cycle, preferably a few pillows at a time to balance the load. Be sparing with the detergent. Use about 1 tablespoon of liquid soap.
Buckwheat hulls: Empty the buckwheat filling onto a large cookie sheet or wide, shallow bowl. Set the buckwheat out in the sun, which will eliminate odors, and wash the shell casing using cold water and a mild detergent.
Step 3: Dry It Thoroughly
It’s crucial to get the pillow completely dry—otherwise you risk mildew. Skip the auto-dry setting on your clothes dryer because the sensors will detect only surface moisture, leaving you with a pillow that’s still damp on the inside.
Instead, many pillows can be dried for a good hour on moderate heat. Adding a couple of dry towels will speed things up. Toss in two fresh tennis balls or dryer balls, as well, and they’ll keep the filling from clumping as they bounce around the drum.
When drying down or feather pillows, however, use the no-heat air-dry setting (it will take a while) and dryer balls or tennis balls to break up clumps.
If the weather is mild, you can also hang most pillows on the clothesline until they’re dried all the way through. Whichever drying technique you use, you still need to check for moisture inside the pillow. If none remains, it’s time to make the bed.
We recommend using pillow covers to protect pillows from substances such as sweat, body oils, and face cream. Launder both the pillow cover and the pillowcase regularly—say, once a week—along with your sheets.
