How to Wash Pillows & How Often You Should Clean Them

How often do you wash your pillows? Probably not as much as you should. Regular bed pillows should be washed at least once or twice a year or more, depending on if you have pets or allergies, or you are a sweaty sleeper. Throw pillows, on the other hand, can go longer between washes.

Here’s how to wash pillows without ruining them.

Experts Delah Gomasi, managing director and CEO of Australia-based MaidForYou; Katie Dills, brand president of The Cleaning Authority; Julia Forbes, a sleep product expert at Sleep Advisor; and Marten Carlson, a Certified Sleep Science Coach at Mattress Clarity, recommended following this step-by-step guide for cleaning pillows.

Memory foam pillows retain water and cannot be put in the washer and dryer. Instead, you’ll want to hand-wash and not fully submerge them. Remove the outer and inner cases (those can go in the washing machine), then sprinkle baking soda over the memory foam and let it sit for an hour. Flip the pillow after the hour and repeat the baking soda application on that side. Combine room-temperature water and gentle, unscented liquid detergent, and wipe the outside of the pillow with it using a cloth. Use constant motion so water doesn’t pool or soak into the pillow. Then allow the pillow to air dry.

Ideally, you would hand-wash and air dry your feather pillows. Most of them, though, can be washed on a gentle cycle and tumble-dried with little to no heat. 

Throw pillows can often be put in the washing machine as per the instructions above, but be sure to remove all covers and check the tag first. If your throw pillows have decorative elements that can’t be removed, spot-clean them with a mild detergent and cool water, or get them dry-cleaned. Remember not to put them in the dryer if you can avoid it — air drying is always best.

If you sweat at night or regularly go to bed with wet hair or hair products in, your pillows may start to have a yellow or brown stain and a bit of an odor. You can neutralize this by sprinkling the surface with baking soda and letting it sit for an hour. Then wash your pillows with Forbes’ suggested solution: A mixture of half a cup of vinegar, one cup of dishwasher detergent, 3/4 cup of baking soda, and three tablespoons of liquid laundry detergent. “This combination can help get out the toughest stains and smells from your pillow,” Forbes says.

As long as you’re following the instructions on your pillow’s tag, you should be able to wash it without ruining it. But if the tag has worn off (or it never had one to begin with), the best bet is to hand-wash the pillow and air dry it. Dills has some other advice as well: Don’t stuff your washer with more than two pillows, because it “can cause uneven washing and even trigger error warnings from your machine,” she says. 

Also, go easy on the detergent. With pillows in particular, your washing machine might have a hard time getting all of it out before the cycle is finished if you use too much.
