If you’re wondering whether you can wash a memory foam pillow, you’re not alone. Memory foam pillows are popular for their comfort and support — but they require special care to keep them clean, fresh, and long-lasting.
In this complete guide, we’ll cover how to wash, spot clean, and maintain your memory foam pillow properly without damaging its structure.
1. Can You Wash a Memory Foam Pillow?
The short answer: you can clean it, but you can’t machine-wash it.
Memory foam is made of viscoelastic material that absorbs water easily and takes a long time to dry. If submerged or put in a washing machine, the foam can tear, lose shape, or trap moisture inside — leading to mold or odors.
However, you can safely hand clean, spot clean, deodorize, and wash the removable cover to keep your pillow hygienic and odor-free.
2. Step-by-Step: How to Wash a Memory Foam Pillow
Here’s how to clean it safely without damaging the foam:
2.1 Step 1: Remove the Pillow Cover
Most memory foam pillows come with a removable outer cover — often made of bamboo, polyester, or cotton.
Unzip the cover and remove it.
Check the care label and machine-wash it in cold or lukewarm water.
Dry it completely before putting it back.
2.2 Step 2: Spot Clean the Foam
For small stains or spills, you can spot clean the foam.
● You’ll need:
A small bowl of lukewarm water
Mild detergent (gentle dish soap or laundry liquid)
A clean cloth or sponge
● Instructions:
Mix a few drops of detergent into water.
Dip the cloth into the soapy water and wring it out.
Gently blot the stained area — don’t rub or soak the foam.
Wipe with a second cloth dampened with plain water to remove soap residue.
Pat dry with a towel and air dry completely before using again.
2.3 Step 3: Deep Clean Occasionally
If your pillow needs a more thorough cleaning (every 3–6 months), try this:
Fill a sink or tub with lukewarm water and add a small amount of mild detergent.
Submerge the pillow lightly and press gently to allow water to flow through (don’t twist or wring).
Drain the soapy water and refill with clean water to rinse.
Gently press out excess water — never twist.
Lay the pillow flat on a clean towel and air dry in a well-ventilated area for 24–48 hours.
2.4 Step 4: Deodorize Between Washes
Over time, your pillow can absorb odors from sweat and hair products.
Here’s how to freshen it up:
Sprinkle baking soda evenly over the pillow surface.
Let it sit for 30–60 minutes.
Vacuum the powder off using a handheld vacuum or upholstery attachment.
This removes odors and refreshes the foam without water exposure.
3. How to Wash the Pillow Cover
Most covers are designed for easy cleaning:
● Machine wash on gentle cycle using cold water.
● Use mild detergent (no bleach or harsh chemicals).
● Air dry or tumble dry on low heat.
● Wash your cover every 1–2 weeks to prevent oil and dirt buildup — especially if you have allergies or sensitive skin.
4. What Not to Do When Washing a Memory Foam Pillow
To keep your pillow in perfect condition, avoid these common mistakes:
● Don’t machine-wash or machine-dry the foam.
Agitation and heat will break down the structure and cause it to crumble or lose shape.
● Don’t use hot water.
Heat can damage the foam’s elasticity and shorten its lifespan.
● Don’t twist or wring the foam.
This can tear the material and create weak spots.
● Don’t use strong detergents or bleach.
Harsh chemicals can degrade the foam and cause discoloration.
● Don’t expose to direct sunlight for long periods.
UV light and heat can harden or crack the foam over time.
5. How Often Should You Clean a Memory Foam Pillow?
Spot clean: Every 1–2 months or as needed.
Deodorize: Every 1–2 months with baking soda.
Deep clean: Every 3–6 months for best hygiene.
Cover wash: Weekly or bi-weekly.
Regular cleaning not only keeps your pillow smelling fresh but also extends its life span and prevents bacteria buildup.
6. How to Dry a Memory Foam Pillow Properly
Drying is just as important as cleaning:
After washing, press out water gently using a clean towel.
Place it in a well-ventilated area.
Let it air dry for 24–48 hours before using.
To speed drying, place a fan nearby or use a low-heat hair dryer from a distance.
Make sure the pillow is 100% dry before putting the cover back on — trapped moisture can cause mold or odor.
7. Keeping Your Memory Foam Pillow Fresh Longer
Between washes, you can maintain freshness easily:
● Use a pillow protector to prevent sweat, oils, and spills from reaching the foam.
● Air out your pillow weekly by removing the cover and leaving it in a ventilated space.
● Rotate or flip the pillow every few weeks to maintain even wear.
If your room is humid, use a dehumidifier to prevent moisture buildup.
These small steps reduce the need for frequent washing and extend your pillow’s life.
8. FAQ
1. Can I put a memory foam pillow in the washing machine?
No. The agitation and spin cycles can destroy the foam. Always hand wash or spot clean.
2. Can I dry a memory foam pillow in a dryer?
No — the heat can melt or deform the foam. Air drying is the only safe option.
3. How do I remove sweat stains or yellowing?
Mix a small amount of baking soda and water into a paste, apply gently to stains, let it sit for 10 minutes, then blot clean with a damp cloth.
4. How do I eliminate odors from memory foam?
Sprinkle baking soda, let sit for an hour, then vacuum. For persistent smells, air the pillow outside (in the shade) for several hours.
5. When should I replace my memory foam pillow?
Every 2–3 years, or sooner if it loses shape, feels uneven, or smells even after cleaning.
