How to Wash a Pillow: Complete Guide & Expert Tips | 2025

Updated On: August 6, 2025

You spend about 56 hours every week with your face pressed against your pillow, yet when was the last time you actually washed it? While most of us diligently wash our pillowcases weekly, the pillows themselves often go neglected, accumulating sweat, body oils, dead skin cells, and dust mites that can trigger allergies and affect your sleep quality.

The good news? Most pillows can be safely washed in your washing machine with the right technique. Whether you're dealing with synthetic fill, down feathers, or wondering how to wash pillows in the washing machine without damaging them, this comprehensive guide will walk you through everything you need to know.

In this article, you'll discover the proper washing frequency, step-by-step instructions for different pillow types, special tips for top-loading washers, and expert advice on maintaining fresh, clean pillows year-round.

Can You Put Pillows in Washing Machine? The Quick Answer

Yes, you can wash pillows in washing machine! In fact, most standard bed pillows filled with synthetic materials, down, or feathers are perfectly safe for machine washing. This applies to polyester-filled pillows, cotton pillows, and most down alternative options that grace bedrooms across the country.

However, not all pillows are created equal when it comes to machine washing. Memory foam and solid latex pillows should never go in the washing machine as the agitation can break down their structure. These specialty pillows require hand washing or spot cleaning only.

Always check the care label first, but rest assured that the majority of traditional bed pillows can handle a gentle cycle in your washer when done correctly.

How Often Should You Wash Your Pillows?

According to cleaning experts and organizations like the American Cleaning Institute, pillows should be washed at least twice a year, though many professionals recommend quarterly washing every 3-4 months for optimal hygiene.

Signs it's time to wash your pillows include:

  • Yellowing or discoloration on the pillow surface
  • Noticeable odors, even mild musty or sour smells
  • The pillow feels less fluffy or supportive than usual
  • Visible stains from sweat, drool, or spills
  • You've been sick or dealing with allergies
  • It's been more than 6 months since the last wash

Consider washing pillows more frequently if you sweat heavily at night, eat in bed, have pets that share your bed, or suffer from allergies. Guest room pillows that see less use can typically go longer between washes.

How to Wash Pillows in the Washing Machine: Step-by-Step Guide

Follow these detailed steps to ensure your pillows come out fresh and maintain their shape:

Step 1: Prepare Your Pillows

Remove all pillowcases and pillow protectors. These should be washed separately with your regular bedding. Inspect pillows for any rips or tears - damaged pillows shouldn't go in the washer as filling may escape.

Step 2: Pre-treat Stains

For visible stains, apply a small amount of laundry detergent or stain remover directly to the spot. Gently work it in with your fingers and let it sit for 10-15 minutes before washing.

Step 3: Load the Washer Properly

Always wash two pillows at once to keep the washer balanced. This prevents the machine from becoming lopsided during the spin cycle and ensures even cleaning. Position pillows on opposite sides of the drum.

Step 4: Choose Your Settings

Select the gentle or delicate cycle with warm water (unless the care label specifies otherwise). The gentle cycle protects the pillow's structure while still providing thorough cleaning. Avoid the bulky or heavy-duty cycle - these are too aggressive for pillows.

Step 5: Add Detergent Wisely

Use only 1-2 tablespoons of mild liquid detergent - about half what you'd use for a regular load. Too much detergent creates excess suds that are difficult to rinse out completely. Liquid detergent is preferred over powder as it dissolves better and leaves less residue.

Step 6: Run an Extra Rinse

Always select the extra rinse option if available. This ensures all detergent is thoroughly removed from the pillow's interior, preventing buildup that can make pillows feel stiff or attract dirt more quickly.

How to Wash Pillows in Top Loading Washer?

Washing pillows in a top-loading washer with an agitator requires special care to prevent damage and ensure proper cleaning.

For top-loading washers with agitators: Position pillows vertically around the agitator rather than laying them flat. This minimizes contact with the agitator and reduces the risk of the filling getting bunched up or the pillow cover tearing. Think of standing the pillows up like books on a shelf.

Balancing techniques for top loaders: Add 2-3 large bath towels between the pillows to prevent them from shifting to one side during the spin cycle. This helps maintain balance and prevents the washer from stopping mid-cycle due to an unbalanced load.

Special considerations: Run the agitator for only 1-2 minutes on the gentle cycle if possible. Some experts recommend using a laundromat's front-loading commercial washers for particularly valuable pillows, as these machines are gentler and have larger capacities.

How to Wash Old Pillows and Clean Dirty Pillows?

Old or heavily soiled pillows need extra attention to restore freshness:

Deep Cleaning Method

For pillows that haven't been washed in over a year or show significant discoloration:

  • Fill your washer with hot water (if care label allows)
  • Add regular detergent plus 1/2 cup of washing soda or borax
  • Add 1/4 cup of bleach for white pillows (skip for colored pillows)
  • Let pillows soak for 30 minutes before running the cycle
  • Run through two complete wash cycles with an extra rinse

When to Replace Instead

If your pillow fails the "fold test" (fold it in half - if it doesn't spring back), has persistent odors after washing, or shows extreme yellowing that won't come clean, it's time for a replacement. Most pillows should be replaced every 1-2 years regardless of washing.

How Many Pillows Can I Wash at Once?

The optimal number is two standard-sized pillows per load. This creates perfect balance in the washer while allowing adequate water circulation for thorough cleaning.

Guidelines by pillow size:

  • Standard/Queen pillows: 2 at a time
  • King pillows: 2 if your washer is large enough, otherwise 1 with towels for balance
  • European square pillows: 1-2 depending on washer capacity
  • Body pillows: 1 at a time due to size

Never overload your washer with more than 2-3 pillows, as this prevents proper cleaning and can damage both the pillows and your machine. For households with many pillows to wash, plan multiple loads rather than cramming them all in at once.

How to Wash Pillow Inserts Properly by Type?

Different pillow materials require specific care to maintain their integrity and comfort:

Down and Feather Pillows

Use cool to warm water on the gentle cycle with minimal detergent. These natural fills can clump if washed too aggressively. Add an extra spin cycle to remove excess water, as down retains moisture. Some luxury down pillows may require professional cleaning.

Synthetic and Polyester Pillows

These are the easiest to wash and can handle warm water on a normal gentle cycle. They dry faster than natural fills and are less likely to clump. Use regular amounts of mild detergent and ensure thorough rinsing.

Memory Foam and Latex Pillows

Never machine wash solid memory foam or latex pillows! Instead:

  • Spot clean stains with mild detergent and damp cloth
  • Sprinkle baking soda on both sides, let sit for an hour, then vacuum
  • Air dry in a well-ventilated area away from direct heat
  • For deep cleaning, submerge briefly in lukewarm soapy water, gently squeeze, rinse, and air dry completely

Buckwheat Hull Pillows

Empty the hulls into a large bowl and sun-dry them while washing only the outer shell according to its care instructions. Never wash the buckwheat filling itself.

Drying Your Pillows: Essential Tips

Proper drying is crucial to prevent mildew and maintain pillow shape:

Machine Drying

  • Use low or medium heat for synthetic pillows
  • Select air-dry or no-heat setting for down/feather pillows
  • Add 2-3 clean tennis balls or dryer balls to prevent clumping and speed drying
  • Check and fluff pillows every 30 minutes
  • Ensure pillows are completely dry before use (may take 2-3 cycles)

Air Drying

  • Lay pillows flat on a clean surface in direct sunlight if possible
  • Flip every few hours for even drying
  • Ensure good air circulation
  • Allow 24-48 hours for complete drying
  • Best for delicate or vintage pillows

The key is patience - using high heat to speed drying can damage pillow materials and create hot spots that feel dry outside while remaining damp inside.

Common Mistakes to Avoid

Protect your pillows and ensure effective cleaning by avoiding these common errors:

  • Using too much detergent: Excess soap creates residue that attracts dirt and makes pillows feel stiff. Stick to 1-2 tablespoons maximum.
  • Washing damaged pillows: Even small tears can become large holes in the washer, spreading filling throughout your machine.
  • Skipping the extra rinse: Detergent trapped inside pillows can cause skin irritation and reduce pillow lifespan.
  • Using hot water on delicate fills: High temperatures can damage down feathers and cause synthetic fills to clump.
  • Incomplete drying: Putting away damp pillows invites mold, mildew, and musty odors. When in doubt, dry longer.
  • Overloading the washer: Too many pillows prevent proper cleaning and can damage your machine's motor.

Pro Tips for Maintaining Clean Pillows

Extend the time between washes and keep pillows fresher with these expert strategies:

  • Use pillow protectors: Zippered protectors create a barrier against sweat, oils, and allergens. Wash these weekly with your sheets.
  • Monthly maintenance: On sunny days, hang pillows outside for a few hours to air out. The UV rays help eliminate odors and bacteria naturally.
  • Fluff daily: Give pillows a good shake and fluff each morning to redistribute filling and prevent permanent flat spots.
  • Rotate regularly: Like mattresses, pillows benefit from rotation. Flip and turn them weekly to ensure even wear.
  • Invest in quality: Better pillows withstand washing better and last longer, making them more economical over time.
  • Create a washing schedule: Mark your calendar for quarterly pillow washing to maintain a consistent cleaning routine.

Frequently Asked Questions

Can You Wash Pillows in Washing Machine with Fabric Softener?

Skip the fabric softener when washing pillows. It can coat the fibers and reduce the pillow's ability to absorb moisture, making it less breathable. The coating can also attract more dirt over time.

How Do You Wash Yellowed Pillows?

For yellowed pillows, create a soaking solution with hot water, 1 cup of laundry detergent, 1 cup of powdered dishwasher detergent, 1 cup of bleach (for white pillows), and 1/2 cup of borax. Soak for 30 minutes before washing normally.

Why Do My Pillows Smell After Washing?

Musty smells indicate the pillows weren't dried completely. Rewash them and ensure thorough drying with good air circulation. Add 1/2 cup of white vinegar to the rinse cycle to eliminate odors.

Can You Wash Foam Pillows in the Washing Machine?

No, solid foam pillows should never go in the washing machine. The agitation will tear the foam apart. Stick to spot cleaning and air drying for these pillow types.

How Long Do Pillows Take to Dry in the Dryer?

Synthetic pillows typically dry in 1-2 hours on low heat. Down and feather pillows may take 2-4 hours with regular fluffing. Always check the center of the pillow for dampness before considering it fully dry.

Should You Wash New Pillows Before Using Them?

While not mandatory, washing new pillows can remove manufacturing residues and odors. If you have sensitive skin or allergies, washing before first use is recommended.

Keep Your Pillows Fresh and Clean

Washing your pillows doesn't have to be intimidating. With the right technique, you can easily maintain fresh, hygienic pillows that contribute to better sleep and overall health. Remember to wash pillows every 3-6 months, always balance your load with two pillows, use minimal detergent, and ensure complete drying.
