How Often to Wash Pillows, According to Laundry Experts

While you may wash your pillowcases weekly, when was the last time you washed your pillows? Bed and throw pillows shouldn't be neglected, as they are susceptible to a buildup of bacteria, oil, skin cells, and dust, just like other pieces of bedding. It's true that you don't need to wash pillows as frequently as sheets and pillowcases, but the occasional wash will extend longevity and improve your home's environment. To ensure your pillows are being cleaned frequently enough, we spoke to cleaning experts who shared how often you should wash them.

Importance of Washing Pillows

Washing your pillows regularly ensures a cleaner and better sleeping environment. "Washing your pillows is essential for maintaining hygiene and extending the lifespan of the pillows," says Alicia Sokolowski, president and co-CEO of AspenClean. "Over time, pillows accumulate sweat, oils, and dead skin cells, as well as allergens that contribute to odors and allergies."

How Often to Wash Bed Pillows

Aim to wash your bed pillows approximately every three to six months. "Washing them removes the buildup of allergens, bacteria, and grime that accumulate over time," says Sokolowski. Regular washing also extends the lifespan of your pillows. On the other hand, you should wash pillow cases as often as one to two weeks, since they come into direct contact with the skin and hair.

How Often to Wash Throw Pillows

Throw pillows should be washed more often than bed pillows, as they're often kept in busier areas of your home. "For the covers on throw pillows, you should wash every two to four weeks. For the insert, you should wash every two months," says Marla Mock, president of Molly Maid, a Neighborly company. "If throw pillows are in a high-trafficked area, it’s important to wash them frequently because of hygiene but also for aesthetic reasons—if the throw pillows are in the living room, they are seen by guests, so you want to ensure they’re not looking grimy or dirty.

Signs Your Pillows Need to Be Washed

There are a few telltale signs it's time to wash your pillows. Here's what to look out for:

• Unpleasant odor: A musty or moldy smell is one of the most obvious signs your pillows need to be washed.
• Discoloration: Yellow or brown spots on pillows are usually a sign of sweat buildup.
• Allergy symptoms: If you're experiencing increased sneezing, itchy eyes, or a runny nose try washing your pillows, which may have a build up of dust mites or other allergens.
• Loss of fluffiness: Washing and drying your pillows can give them new life when they've lost their plumpness.

Tips for Washing Pillows

Washing bed and throw pillows is straightforward, but there are some tips to keep in mind for best results and longevity.

Check the Care Label

Check the care label before washing your pillows, which will indicate if they are machine-washable. If your pillows can't be laundered in the machine, wash them by hand with warm water and a mild detergent. Let the pillows air-dry completely before putting the covers back on, says Sokolowski.

Pre-Treat Stains

Before washing, pre-treat stains with oxygen bleach or any other gentle stain remover, says Sokolowski.

Wash Two Pillows at a Time

When machine-washing, always place two pillows in the washer at once to keep the machine balanced. "Use mild detergent and choose a gentle cycle with warm water. Run an extra rinse cycle to ensure all the detergent is gone and everything is rinsed thoroughly," says Sokolowski.

Dry on a Low Setting

Dry your pillows on a low heat setting (unless otherwise specified on the label). "Place a couple of tennis balls or dryer balls in with the pillows," says Mock. "This helps with drying time, allows for pillows to stay plump, and prevent clumping. You can also air dry them as well." Make sure the pillows are completely dry to prevent mold or mildew from forming.
