Can You Wash Memory Foam Pillows in the Washing Machine?

If you love the plush, supportive feel of your memory foam pillow, you’re likely wondering how to keep it fresh and clean. The big question often is: “Can you wash memory foam pillows in the washing machine?” The answer, in most cases, is no—most memory foam pillows should not be put in a washing machine, as this can damage the foam’s structure and cause your pillow to lose shape or even break apart.

But that doesn’t mean your pillow has to stay dirty! With the right care, you can keep your memory foam pillow clean, hygienic, and in good condition for years to come.

Why Machine Washing Is Not Recommended

Memory foam is an absorbent, sponge-like material. It’s designed to cradle your head and neck, but it doesn’t fare well with agitation or soaking. Here’s why machine washing is risky:

• Agitation from the machine can make the foam tear, crumble, or deform.
• Soaking the foam traps water deep inside, leading to long drying times and potential mold or mildew.
• Spin cycles can break the foam and reduce its support.

Due to these factors, most pillow care guides and manufacturers recommend alternative cleaning methods.

The Best Way to Clean Your Memory Foam Pillow

Instead of machine washing, memory foam pillows should be cleaned by hand. Here’s a step-by-step guide so you can keep your pillow looking and smelling great without damaging it.

1. Regular Maintenance: Spot Cleaning

• Immediate stains: If you spill something on your pillow, blot the area with a clean, dry cloth right away.
• Mix a gentle solution: Use a small amount of mild detergent mixed with water.
• Apply: Dip a clean cloth or sponge in the soapy water, then gently dab the soiled area.
• Rinse: With a new damp cloth (just plain water), dab the area to remove soap residue.
• Dry: Press with a dry towel to soak up moisture, then let the pillow air dry completely before using.

2. Deep Cleaning: Hand Washing

While you shouldn’t machine wash, it’s sometimes necessary to give your pillow a more thorough clean. Here’s how:

What You’ll Need

• A clean bathtub or large basin
• Mild liquid detergent (free of bleach or harsh chemicals)
• Fresh water
• Towels

Cleaning Steps

1. Fill the tub: Use lukewarm water.
2. Add detergent: Mix in a small amount and swirl until sudsy.
3. Submerge pillow: Carefully lower the pillow in and gently squeeze to allow water and soap to penetrate.
4. Rinse: Drain the soapy water, then refill with clean water. Gently squeeze the pillow until detergent is gone.
5. Gently press water out: Do not wring or twist the foam, as this can cause ripping.
6. Drying: Lay the pillow flat on a dry towel. Roll it up to absorb excess moisture. Then place the pillow in a well-ventilated area and let it air dry completely, preferably in the sun or under a fan. It may take 24–48 hours to dry thoroughly.

Benefits of Properly Cleaning Memory Foam Pillows

Cleaning your memory foam pillow the right way keeps it:

• Sanitary: Reduces dust mites, allergens, and odors.
• Supportive: Maintains the shape and cradling properties.
• Durable: Extends the lifespan by preventing shredding and breakdown.

Common Challenges

• Long drying time: Memory foam can take a day or more to dry, so plan ahead.
• Water absorption: Foam holds water deep within, so never use heat to speed up drying (it can damage the pillow).
• Delicate structure: Avoid rough handling at all stages.

Practical Tips & Best Practices

Here are some useful strategies for maintaining a clean and comfy memory foam pillow:

Use a Pillow Protector

• Invest in a high-quality, waterproof pillow protector to keep sweat, oils, and spills off your pillow.

Regular Pillowcase Changes

• Wash pillowcases weekly to prevent skin oils and dirt from reaching the foam.

Freshen Between Washes

• Sprinkle a small amount of baking soda on the pillow, let it sit for 30 minutes, then vacuum with a brush attachment for odor control.

Avoid Direct Sunlight (when drying indoors)

• If drying inside, keep the pillow out of direct sunlight as UV rays can break down the foam over time. If outdoors, a few hours of filtered sunlight is okay.

Do Not Bleach or Iron

• Bleach can break down foam and ironing will melt or damage it.

Fluff Pillow Regularly

• Give your pillow gentle shakes or squeezes daily to keep it airy and supportive.

What About Shredded Memory Foam Pillows?

Some pillows contain shredded memory foam instead of a solid block. While these may sometimes have washable cases, the filling itself still should not be placed in a washer or dryer unless the manufacturer says otherwise. The best option is usually to remove the outer cover for machine washing and follow the hand-washing method for the foam inside.

When Should You Replace Your Memory Foam Pillow?

Even with careful cleaning, memory foam pillows eventually reach the end of their lifespan. It’s time for a new pillow if:

• You notice permanent indentations or flat spots.
• The foam is breaking apart or crumbling.
• There’s a persistent odor that doesn’t fade after cleaning.
• Allergies worsen or the pillow looks unsanitary after cleaning.

Most memory foam pillows last about 2–3 years with proper care.

Frequently Asked Questions (FAQs)

Can I wash my memory foam pillow in the delicate cycle of my washing machine?

No, even the delicate or gentle cycle is not recommended for memory foam pillows. The agitation and soaking can still damage the foam’s structure. Hand washing is always the safer choice.

How often should I clean my memory foam pillow?

Spot cleans can be done as needed (anytime you notice a stain), and a deep hand wash is recommended every 3–4 months. Always use a pillowcase and protector to reduce the need for deep cleaning.

How can I speed up the drying process for my memory foam pillow?

Never use a dryer or direct heat source. The best way to dry it faster is to place the pillow in a well-ventilated area near a fan or open window. Occasionally pressing with a dry, absorbent towel can also help draw out moisture.

Why does my memory foam pillow smell bad, and how can I get rid of the odor?

New memory foam may have a slight smell called “off-gassing.” Airing out the pillow, using baking soda, or placing it outside (away from direct sunlight) can help. If your pillow has taken on odors from use, regular airing and baking soda treatments can refresh it.

Is there a difference in cleaning methods for gel-infused or shredded memory foam pillows?

Gel-infused pillows should be treated the same as standard memory foam—no machine washing and gentle hand cleaning. For shredded memory foam, check if the cover is removable and machine-washable, but clean the foam filling by hand.
