How to Wash a Pillow in the Washing Machine and Know Which Pillows to Avoid

If you are learning how to wash a pillow in the washing machine, check the care label and filling type before starting. Many polyester, synthetic, down, and feather pillows can be machine washed when their labels allow it, while memory foam, latex, and some specialty pillows need a different approach. Using the wrong cycle or too much detergent can leave filling clumped or slow to dry.

This guide explains which pillows can usually enter the washer, which ones should stay out, how to balance the load, and how to dry the filling completely. You will also learn down-pillow care safely.

Check the Care Label Before Washing

The care label should make the first decision. It can specify washing method, water temperature, cycle type, and drying limits. Follow those directions even when general advice says otherwise.

If the label is missing and you cannot identify the filling, choose a cautious non-machine approach instead of guessing.

Know Which Pillows Can and Cannot Go in the Washer

Many polyester, synthetic-fill, down, and feather pillows can be machine washed when the manufacturer allows it. Memory foam, solid latex, buckwheat, and some specialty pillows generally need another cleaning method.

• Polyester and synthetic fill: Often machine washable when the label permits it.

• Down and feather: Often washable, but gentle action, little detergent, thorough rinsing, and complete drying matter.

• Memory foam: Washer agitation can damage solid foam, so use the maker's non-machine instructions.

• Latex: Machine agitation can damage the core.

• Buckwheat: Keep the hull filling dry.

• Specialty pillows: Cooling layers or mixed constructions may have their own restrictions.

Prepare the Pillow and Balance the Load

Remove outer covers and check the seams. If the label permits machine washing, wash two similar pillows together when possible. This helps balance the washer during spinning.

Do not pack the drum tightly. Pillows need room for water to move through the filling. With one pillow, check the washer manual for balancing bulky items.

Use the Right Cycle and Detergent

For how to wash a pillow in the washing machine safely, follow the water temperature and cycle stated on the care label. When the label gives options, a gentle cycle is suitable for many washable pillows.

Use a small amount of mild liquid detergent. Thick filling can hold suds, so extra detergent may be harder to rinse away. NC State Extension recommends using an extra rinse cycle for feather pillows to help remove remaining detergent. Repeat rinsing if the pillow still feels slippery. 

How to Wash Down Pillows Without Clumping Them

If the care label allows machine washing, how to wash down pillows depends on keeping the load balanced and making sure the filling dries completely. The U.S. Department of Housing and Urban Development advises checking feather-pillow seams for openings before washing and placing two pillows in the washer together to help balance the load.

Follow the pillow’s own care label for the cycle, detergent amount, and drying temperature. After washing, dry the pillow completely and pause during drying to gently redistribute the filling. Avoid twisting or wringing a wet down pillow because that can leave the filling compressed or uneven.

Compare Washing Guidance by Pillow Type

This table helps you quickly check whether a pillow is usually suitable for machine washing and what care point matters most for each filling type.

Dry the Pillow Completely Before Reusing It

Drying matters as much as washing. A pillow may feel dry outside while moisture remains deeper inside. Follow the care label for tumble-drying or air-drying directions.

Where tumble drying is allowed, use the listed low or no-heat setting. Dryer balls can help separate filling. Pause to feel the center and loosen clumps. Do not return the pillow to bed until fully dry.

Avoid Mistakes That Leave a Pillow Lumpy or Damaged

Too much detergent, an overcrowded drum, aggressive agitation, and excessive heat can change the pillow's shape. Skipping the care label is risky because similar pillows may have different construction.

Do not assume a washable removable cover means the pillow core can also enter the machine. Clean the cover separately when needed and follow the maker's instructions for the core.

If You Wash the Pillow at Home

At home, you can inspect seams, follow the label, balance the washer, measure detergent, select the right cycle, add a rinse, and dry the pillow completely. A standard machine-washable pillow may need nothing more.

The limit appears when the pillow cannot be machine washed or the issue extends beyond it. A soiled mattress, box spring, or headboard needs a separate cleaning approach.

If Deeper Bed Cleaning Is Needed

Carpeting NJ's mattress cleaning service is separate from washing a removable pillow at home. It becomes relevant when the mattress or related bed surfaces also need deeper attention.

New Jersey homeowners can review our mattress cleaning service, check our service area, or contact Carpeting NJ. This keeps an ordinary washable pillow as a home task while larger bed-cleaning needs receive a different approach.

Know Which Pillows to Avoid Washing Again

Do not machine wash a pillow when its label prohibits it, the seams are opening, the core is damaged, or the filling type is uncertain. Replacement may make more sense when a pillow has permanently lost its shape or support.

If you already tried to wash a pillow in the washing machine and the filling remains heavily clumped after complete drying, another wash may not restore it. Check the maker's care guidance first.
