Pillows collect sweat, dust mites, dead skin cells, and allergens over time, making regular cleaning essential for better hygiene and sleep quality. If you’re wondering how to wash pillows in a washing machine, the good news is that many pillows are machine washable when cleaned properly.

In this guide, you’ll learn the safest way to wash different pillow types, avoid damage, and keep your pillows fresh, fluffy, and long-lasting. By the you can check our previous article, where we discussed that how you can wash a pillow by hand. Anyway, without wasting anytime, lets jump to the article.

Can You Wash Pillows in a Washing Machine?

Yes, most pillows can be washed in a washing machine, including:

• Down pillows
• Feather pillows
• Polyester fiberfill pillows
• Cotton pillows

However, some pillows should not be machine washed, such as:

• Memory foam pillows
• Latex pillows

Always check the care label before washing to avoid damaging the material.

Why You Should Wash Pillows Regularly

Even if you use pillowcases, pillows still absorb oils, sweat, and dust over time. Washing pillows regularly helps:

• Remove allergens and dust mites
• Eliminate odors
• Improve sleep hygiene
• Extend pillow lifespan
• Keep pillows fluffy and comfortable

Experts recommend washing pillows every 3–6 months.

What You Need Before Washing Pillows

Before starting, gather the following:

• Mild liquid detergent
• Washing machine
• Dryer balls or clean tennis balls
• Clean towels (optional)
• Pillow care instructions

Avoid using too much detergent, as residue can remain trapped inside the pillow filling.

Step-by-Step: How to Wash Pillows in a Washing Machine

Step 1: Read the Care Label

The care label tells you:

• Water temperature
• Washing instructions
• Drying recommendations
• Whether machine washing is safe

Skipping this step may ruin delicate pillow materials.

Step 2: Remove Pillow Covers

Take off:

• Pillowcases
• Protective covers
• Decorative shams

Wash these separately according to fabric instructions.

Step 3: Check for Damage

Inspect pillows for:

• Tears
• Holes
• Weak seams

Small openings can worsen during the wash cycle and release filling into the machine.

Step 4: Load Two Pillows at Once

Place two pillows in the washer to keep the machine balanced during spinning.

For top-loading machines, position pillows vertically if possible.

Step 5: Use a Gentle Cycle

Choose:

• Warm water
• Gentle or delicate cycle
• Mild detergent

Avoid bleach unless the care label specifically allows it.

Step 6: Run an Extra Rinse Cycle

Pillows can trap soap inside the filling. An extra rinse helps remove detergent completely and prevents stiffness.

How to Dry Pillows Properly

Drying is just as important as washing. Damp pillows can develop mold or mildew if not fully dried.

Use Low Heat

High temperatures may damage filling materials or shrink fabrics.

Best dryer settings:

• Low heat
• Medium heat for synthetic pillows only

Add Dryer Balls or Tennis Balls

These help:

• Restore fluffiness
• Prevent clumping
• Improve airflow

Wrap tennis balls in clean socks to reduce noise.

Check Pillows Frequently

Pause the dryer every 20–30 minutes to:

• Fluff pillows manually
• Redistribute filling
• Check moisture levels

Ensure Pillows Are Completely Dry

Even slight dampness inside the pillow can lead to unpleasant odors and mold growth.

A fully dry pillow should feel:

• Light
• Fluffy
• Free from cool or damp spots

How to Wash Different Types of Pillows

Down and Feather Pillows

These are usually machine washable but require gentle handling.

Tips:

• Use mild detergent
• Wash on delicate cycle
• Dry thoroughly to avoid clumping

Polyester Pillows

Synthetic pillows are generally easy to clean.

Tips:

• Warm water works well
• Medium heat drying is usually safe
• Avoid excessive detergent

Memory Foam Pillows

Most memory foam pillows should not go in the washing machine.

Instead:

• Spot clean stains
• Use mild soap
• Air dry completely

Machine washing can damage the foam structure.

Latex Pillows

Latex pillows are not machine washable.

Best cleaning method:

• Spot cleaning
• Gentle hand washing if allowed
• Air drying only

Common Mistakes to Avoid

Using Too Much Detergent

Excess soap can remain trapped inside the pillow, causing stiffness and odors.

Washing One Pillow Alone

This can unbalance the washing machine and strain the drum.

Drying on High Heat

High temperatures may damage pillow filling or shrink the fabric.

Storing Damp Pillows

Never store pillows until fully dry to prevent mold and mildew.

How Often Should You Wash Pillows?

Here’s a simple guideline:

Pillow Item	Recommended Cleaning
Pillowcases	Weekly
Pillow Protectors	Monthly
Pillows	Every 3–6 Months

Regular cleaning keeps your sleep environment healthier and fresher.

Signs It’s Time to Replace Your Pillow

Even with proper washing, pillows eventually wear out.

Replace pillows if they:

• Stay flat after fluffing
• Have persistent odors
• Feel lumpy
• Cause neck discomfort
• Show yellow stains that won’t wash out

Most pillows should be replaced every 1–2 years.
