Pillows play a major role in your comfort and sleep quality—but they also collect sweat, oils, dust mites, bacteria, and odors over time. Learning how to clean a pillow properly is essential if you want a fresher bedroom, better sleep, and a longer-lasting pillow.

But here’s the challenge: different pillows require different cleaning methods. Memory foam, bamboo pillows, down feather pillows, buckwheat pillows—all of them need specific care to avoid damage. And if you also have a pillow top mattress (or are dealing with urine stains on one), care becomes even more important.

This complete guide will teach you exactly what to do, no matter what kind of pillow or bedding you have.

Why Cleaning Your Pillows Matters

Before diving into the specific cleaning methods, here’s why regular pillow cleaning is essential:

• Removes built-up sweat, oils, and odor
• Eliminates dust mites and allergens
• Prevents mold and mildew
• Improves pillow lifespan
• Keeps your mattress and linens fresher
• Promotes overall better sleep quality

Most sleep experts recommend cleaning or washing pillows every 2–4 months, depending on the type.

How to Clean a Pillow (General Method)

For pillows made of polyester, cotton-fill, or down-alternative materials, the general cleaning process works well.

Follow these steps:

1. Check the care label. Always begin by reading the manufacturer’s instructions.

2. Use a gentle cycle. Place two pillows at a time into the washing machine to keep the load balanced.

3. Choose mild detergent. Avoid bleach unless the pillow specifically allows it.

4. Rinse twice. This helps remove soap residue.

5. Dry completely. Use low to medium heat and add dryer balls or tennis balls wrapped in socks to prevent clumping.

If your pillow cannot be machine washed, don’t worry—specific instructions are provided for each pillow type below.

How to Clean a Body Pillow

Body pillows are larger and often heavily used, absorbing more sweat and oils.

Steps to Clean a Body Pillow:

1. Check if it’s machine washable.
   Most body pillows with polyester or fiberfill are safe to wash.
2. Use a large capacity washer.
   Laundromat washers work well if yours is too small.
3. Wash on gentle cycle using warm water and mild detergent.
4. Rinse twice to remove all soap residue.
5. Dry on low heat with dryer balls.
   Larger pillows may need 2–3 cycles to fully dry.
6. If not machine washable:
   Spot clean using mild soap + water and air dry under sunlight.

How to Clean a Bamboo Pillow

Bamboo pillows usually contain shredded memory foam, which should not be machine washed.

To Clean the Bamboo Pillow Cover:

• Machine wash cold on gentle cycle
• Use mild detergent
• Air dry to prevent shrinking

To Clean the Inside Shredded Foam:

1. Do not submerge in water.
2. Lightly spot clean with a damp cloth + mild detergent.
3. Dab gently—avoid oversaturating the foam.
4. Air dry completely before putting the cover back on.

Sunlight also helps deodorize naturally.

How to Clean Urine From Mattress With a Pillow Top

Urine on a pillow-top mattress must be handled quickly to prevent odor and stain penetration.

Step-by-Step Urine Removal Method:

1. Blot the Urine

• Use paper towels or cloth
• Press firmly to absorb moisture
• Do NOT rub—this spreads the stain

2. Apply Vinegar Solution

Mix:

• 1 cup vinegar
• 1 cup warm water
• A few drops of mild dish soap

Spray generously on the affected area.

3. Sprinkle Baking Soda

Cover the damp area with a thick layer of baking soda to neutralize odor.

4. Let Dry 8–12 Hours

Allow the baking soda to fully absorb moisture.

5. Vacuum Thoroughly

Use a strong vacuum to remove powder and residue.

6. For Persistent Odors

Spray with hydrogen peroxide + baking soda solution (light mist only), let it dry, and vacuum again.

Avoid oversaturating pillow tops, as they dry slowly.

How to Clean a Pillow Top Mattress (General Care)

Even without stains, pillow-top mattresses need routine maintenance.

Steps to Clean a Pillow Top Mattress:

1. Vacuum monthly using an upholstery attachment.
2. Spot clean stains using mild detergent + warm water.
3. Deodorize by sprinkling baking soda across the entire surface.
4. Let sit for several hours, then vacuum thoroughly.
5. Air out the mattress by letting sunlight in or using a fan.
6. Use a waterproof mattress protector to prevent future accidents.

Avoid steam cleaners—excess moisture can ruin pillow tops.

How to Clean a Buckwheat Pillow

Buckwheat pillows require special handling because the hulls absorb moisture and cannot get wet.

Important:

NEVER wash the buckwheat hulls.

Proper Way to Clean a Buckwheat Pillow:

1. Remove the Hulls

Empty the hulls into a bucket or clean container.

2. Wash the Pillow Cover

• Machine wash the cover
• Use gentle cycle with cold water
• Air dry completely

3. Refresh the Hulls

• Lay them under direct sunlight for 2–3 hours
• This kills bacteria and removes odors naturally

4. Reassemble

Pour the dry hulls back into the pillow.

Replace hulls every few years if they become dusty, brittle, or moldy.

How to Clean a Down Feather Pillow

Down pillows are luxurious but need delicate care.

To Clean Down Feather Pillows:

1. Use a Large Front-Load Washer

Avoid top-load machines with agitators—they can tear the pillow.

2. Wash on Gentle Cycle

• Warm water
• Mild liquid detergent (avoid powder detergents)
• No bleach or fabric softener

3. Extra Rinse Cycle

Feathers trap detergent, so a second rinse is essential.

4. Drying (Very Important)

• Tumble dry LOW heat
• Add 2–3 dryer balls or tennis balls
• Fluff the pillow between cycles
• Dry for 2–3 hours until completely moisture-free

Wet feathers can develop a strong odor, so drying thoroughly is crucial.

How to Clean a Foam Pillow

Foam pillows (solid memory foam or latex foam) cannot be machine washed.

Steps to Clean a Foam Pillow:

1. Vacuum the Surface

Use an upholstery or brush attachment to remove dust and dead skin.

2. Spot Clean Stains

• Mix mild detergent + warm water
• Dip a cloth, wring it out, and gently blot stains
• Avoid saturating the foam

3. Deep Clean (Optional)

If the pillow smells strongly:

1. Fill a bathtub with lukewarm water + gentle detergent
2. Submerge pillow briefly and squeeze gently
3. Drain soapy water and refill with clean water
4. Rinse by pressing the pillow until the water runs clear

4. Air Dry Completely

• Lay on a flat surface
• Preferably outdoors or under a fan
• Drying may take 24–48 hours
• NEVER use a dryer

Heat breaks down foam structure.

How Often Should You Clean Your Pillows?

Different pillow types have different cleaning schedules:

• Polyester pillows: every 2 months
• Down/feather pillows: every 3–6 months
• Foam pillows: every 2–4 months
• Bamboo pillows: every 3–4 months
• Buckwheat pillows: wash cover monthly; refresh hulls every 3–6 months
• Body pillows: every 2–3 months

Mattresses should be deep cleaned every 3–4 months.

Pro Tips to Keep Pillows Fresher Longer

• Use pillow protectors—they reduce washing frequency
• Air pillows in sunlight monthly
• Always fully dry pillows before use
• Replace pillows every 1–2 years depending on material
• Rotate body pillows to prevent uneven wear
• Keep pets off bedding to reduce odors and bacteria
