How to Wash a Memory Foam Pillow to Extend Its Lifespan, According to Laundry Pros

Picture this: You’re finally in bed after a long day, your bed sheets are freshly washed, and your comforter is still warm from the dryer. But once your head hits the bed, you realize your memory foam pillows haven’t been cleaned in a while (or maybe ever). But don’t fret—you can still remedy the situation and freshen up your favorite pillows with ease.

We consulted with two cleaning experts to get all the tips and tricks you need to clean your favorite memory foam pillows safely and effectively and extend their lifespan.

How Often to Wash Memory Foam Pillows

If you've never cleaned your memory foam pillows before, you aren't alone. But the truth is, just like other types of pillows, they do require occasional cleaning. Most people don't realize how much dirt and bacteria pillows build up over time—even with pillowcases!

"Memory foam pillows should be cleaned about every 3–4 months, and spot cleaned more often," explains Scott Schrader, founder of cleaning company CottageCare. 

However, if you suffer from allergies or you’re a particularly hot sleeper who often sweats, then a monthly cleaning is preferable, adds cleaning professional Jessica Gonzalez. This will help alleviate odors, allergen, and bacteria growth.

Are Memory Foam Pillows Machine Washable?

Memory foam pillows cannot be cleaned in a washing machine, as the agitation will break down the foam. As a blanket rule, Schrader always recommends checking the care label of your specific pillow before starting the cleaning process—most can be cleaned via a gentle hand-washing.

How to Wash Memory Foam Pillows

Hand-washing a memory foam pillow isn’t as daunting as it sounds. You only need a few materials, a gentle touch, and a bit of patience. Remember to also allow for adequate drying time (since they can’t be popped into the dryer like sheets). 

Materials Needed

• Large basin or bathtub
• Gentle detergent
• Clean towels
• Water

Instructions

1. Remove any pillowcases or pillow protectors and set them aside. Most pillow protectors can be washed in the washing machine (like pillowcases)—but always check the care tag beforehand, Gonzalez says.
   
2. Fill your basin or tub with lukewarm water and add a small amount of gentle detergent.
   
3. Slowly submerge and gently squeeze the pillow in the water, but don’t rotate it. A light touch is key here.
   
4. Rinse thoroughly until the pillow is soap-free.
   
5. Gently towel the pillow off.
6. Place the pillow on a drying rack or other ventilated surface, ensuring the pillow is in its proper shape as it dries. Allow it to dry completely (usually 48 hours) before you use it again.

How to Remove Odors from Memory Foam Pillows

To remove any lingering odors from memory foam pillows, both Gonzalez and Schrader swear by baking soda. "You can regularly freshen and deodorize them by sprinkling baking soda onto a dry pillow, letting it sit for a few hours, and then vacuuming it off," Schrader explains.

Using the baking soda trick in between more detailed cleanings as a way to stave off any musty odors. 

How to Spot Clean a Memory Foam Pillow

To spot clean a memory foam pillow, simply dip a clean cloth into a water and gentle detergent mixture and blot at the stain. Schrader warns against scrubbing hard, as it might damage the foam.

You’ll also want to allow 24-48 hours for the pillow to dry, even with spot cleaning.

These simple care tips from our cleaning pros will help you maintain your memory foam pillow and extend its lifespan—so you can keep sleeping soundly night after night. Here are some things to keep in mind:

• Never machine wash your foam pillow.
  
• Keep the pillow away from direct sun and heat.
  
• Use baking soda for monthly scent refreshes.
  
• Replace your memory foam pillow after 2-3 years, or when it is no longer supportive or holding its shape.
