The most reliable approach to how to wash pillows starts with the right product and the right technique. Anyone who has struggled with how to wash pillows will find that consistency matters more than any single method. This guide covers how to wash pillows from every angle. Each method for how to wash pillows is explained with the exact steps that deliver reliable results.
Most people wash their pillowcases regularly but forget about the pillow itself. Over time, pillows accumulate sweat, dead skin cells, dust mites, and bacteria. That buildup affects sleep quality, triggers allergies, and shortens the life of the pillow.
Knowing how to wash pillows correctly keeps them hygienic, extends their lifespan, and makes a real difference for your sleep environment. These eight steps cover machine washing for the most common pillow types.
Why pillow hygiene matters more than you think
You spend a third of your life with your face pressed against a pillow. The American Academy of Allergy, Asthma and Immunology notes that dust mites are one of the most common household allergens, and pillows are one of their primary habitats.
Regular washing helps:
- Reduce dust mite populations
- Remove sweat and skin oil buildup
- Eliminate bacteria and mold that thrive in warm, humid conditions
- Maintain fluffiness and loft over time
Pillow hygiene is not a luxury. It is a practical health habit.
The Asthma and Allergy Foundation of America recommends regular washing of pillows and bedding to reduce dust mite populations, one of the most common indoor allergen triggers.
How often should you wash pillows
The general recommendation is every three to six months, or more frequently if:
- You have allergies or asthma
- You sweat heavily during sleep
- A pet sleeps in your bed
- Someone in the household has been ill
Pillowcases should be washed weekly as part of your regular laundry routine.
Which pillow types can go in the washer
Before washing, check the care label. Most pillow types are machine washable:
- Polyester fill: Machine washable, most common type.
- Down and feather: Machine washable on a gentle cycle with mild detergent.
- Down alternative (synthetic fill): Machine washable, similar to polyester.
- Memory foam: Not machine washable. Hand wash or spot clean only. Machine washing destroys the foam structure.
- Buckwheat: Remove the filling and wash the cover only.
- Latex: Not machine washable. Wipe clean with a damp cloth.
If the care label says dry clean only, follow that instruction.
8 steps to wash pillows and get them actually clean
Step 1: Read the care label
Always check the care label before washing. Look for temperature recommendations, detergent type, and whether tumble drying is appropriate. Different fills require different settings.
Step 2: Remove the pillowcase and pillow protector
Wash the pillowcase and any mattress-style pillow protector separately according to their own care instructions. You are washing the pillow itself in this process.
Check the pillow for any tears or weak seams before loading it into the machine. A tear will allow fill material to escape and clog the machine.
Step 3: Wash two pillows at a time
Loading two pillows at once balances the drum of a top-loading machine and ensures more even washing. For a front-loading machine, one pillow at a time is often sufficient.
This also helps the machine complete a balanced spin cycle, which matters for effective rinsing and extraction of excess water.
Step 4: Use a small amount of liquid detergent
Use less detergent than you think you need. Too much soap leaves residue in the fill that is difficult to rinse out and can cause clumping. For down and feather pillows, use a down-specific detergent or a small amount of mild liquid detergent.
Powder detergent can leave granules trapped in fill material. Liquid is the better choice for washing pillows.
Step 5: Set the right cycle
For most pillows, use a gentle or delicate cycle with warm water. Hot water can break down fill material and cause shrinkage in some fabric shells.
For heavily soiled pillows, a normal cycle with cold or warm water is acceptable.
Step 6: Run an extra rinse cycle
This step is important. Detergent trapped inside pillow fill causes clumping, stiffness, and lingering soap odor. Running the pillow through an extra rinse cycle ensures all detergent is completely removed.
If you can wash a pillow in a machine with a dedicated rinse setting, use it here.
Step 7: Dry thoroughly
Incomplete drying is the most common cause of mold growth inside pillows. Damp fill creates ideal conditions for bacteria and mildew.
Place the pillows in the dryer on a low or medium heat setting. Add two or three clean tennis balls or dryer balls to the dryer. They break up clumps and restore loft as the pillow dries.
Drying may take two to three hours for thick pillows. Check for damp spots by pressing the center of the pillow. It should feel completely dry and evenly fluffy throughout.
Step 8: Let them air out before putting them back
Once the pillows come out of the dryer, let them sit in a well-ventilated area for 30 minutes before putting them back on the bed. This final airing ensures any remaining moisture disperses completely.
Can you put pillows in the washer if they have stains?
Yes, and you should pre-treat stains before washing. For yellowing caused by sweat:
- Mix a solution of one cup of hydrogen peroxide, half a cup of white vinegar, and a quarter cup of dish soap.
- Apply to yellowed areas and let sit for 30 minutes.
- Wash as normal.
For other stains, use a mild stain remover appropriate for the fabric, applied and allowed to sit before machine washing.
When to replace a pillow
Even with regular washing, pillows have a lifespan. Replace your pillow when:
- It does not spring back to shape when folded in half
- It has a persistent odor that washing does not remove
- The fill has compacted into lumps that cannot be broken up
- It is more than two years old (for synthetic fill) or three to five years old (for down)
How to wash pillows that have turned yellow
Yellow staining on pillows is extremely common. It comes from sweat, body oils, and saliva absorbed into the fill over months of use. Yellow pillows are not necessarily dirty in a harmful sense, but the discoloration signals that the pillow needs a thorough wash.
For how to wash pillows with significant yellowing, a pre-treatment soak delivers better results than washing alone.
Fill your washing machine or bathtub with hot water. Add one cup of powdered dishwasher detergent, half a cup of washing soda (not baking soda), and half a cup of Borax. Submerge the pillow and allow it to soak for 30 minutes to one hour.
Then transfer to the washing machine and run a full cycle. The combination of enzymes, sodium carbonate, and Borax breaks down the proteins and oils that cause yellow staining. Follow the drying steps in this guide to complete the process.
Most pillows emerge from this treatment significantly whiter. Severe yellowing may require two treatments.
How to wash pillows in a top-loader vs front-loader
The washing machine type affects the approach.
Top-loading machines with an agitator: Place the pillows vertically in the drum, one on each side of the agitator, to keep the machine balanced. Use the gentle cycle.
Top-loading machines without an agitator: Lay pillows flat in the drum. These machines are gentler and handle pillows well on a normal cycle.
Front-loading machines: Load one pillow at a time to ensure thorough washing without the pillow bunching up against the door. A gentle or delicate cycle works best.
Understanding how to wash pillows in your specific machine type prevents uneven washing and the spin-cycle imbalance that can cause machine errors.

Frequently asked questions about how to wash pillows
How to wash pillows in a top-load washer without them getting lumpy? Place two pillows at a time to balance the drum. Use the gentle cycle. Add dryer balls during the dry cycle and run multiple drying cycles if needed. The dryer balls break up clumps as the fill dries. This is the most reliable approach for how to wash pillows in top-loading machines and restore their original shape.
How to wash pillows that cannot go in the dryer? Some down and feather pillows require air drying. After machine washing on a gentle cycle, place them flat in a sunny, well-ventilated area. Fluff and rotate every few hours. This may take a full day to complete. Knowing how to wash pillows that are air-dry only prevents shrinkage and damage.
How to wash pillows with a strong smell? Add half a cup of white vinegar to the washing machine along with a small amount of detergent. The vinegar neutralizes odor molecules during the wash cycle and rinses away completely. This method for how to wash pillows with persistent odors is effective for both mildew and sweat-related smells.
How to wash pillows that have mold or mildew? First, check whether the pillow is salvageable. If mold has penetrated throughout the fill, replacement is the safer option. For surface mildew on the fabric shell, pre-treat with a diluted hydrogen peroxide solution, then wash on a warm cycle. If the smell or staining persists after washing, discard the pillow. How to wash pillows with visible mold requires careful evaluation of whether cleaning is sufficient.
