We spend about a third of our lives with our faces pressed against our pillows. Over time, those pristine, fluffy bed accessories naturally accumulate a hidden buildup of sweat, body oils, dead skin cells, drool, and dust mites. This accumulation is what causes pillows to develop unsightly yellow stains and a musty odor.
While many people remember to wash their pillowcases regularly, the pillows themselves are often neglected. Sleeping on a dingy pillow can trigger allergies, cause skin breakouts, and compromise your sleep quality. Fortunately, most pillows can be easily laundered and restored to their former glory. This comprehensive guide will take you through the step-by-step process of washing and refreshing different types of pillows to ensure a cleaner, healthier night of rest.
Understanding Your Pillow Material
Before you throw your pillows into the washing machine, you must determine what material they are made of. Different fills require drastically different care methods. Check the manufacturer care label attached to the pillow for specific instructions. If the label has faded or been cut off, use the guidelines below to identify your pillow type.
Down and Feather Pillows
These pillows are filled with the soft undercoating of geese or ducks. They are highly durable and can generally handle machine washing, provided you use a gentle cycle and dry them thoroughly.
Synthetic Fiberfill and Down Alternative Pillows
Typically made from polyester, these are the most common type of pillow. They are highly resilient and budget-friendly. Most polyester pillows are completely machine washable and dryable, though they can sometimes clump if exposed to high heat.
Memory Foam and Latex Pillows
Whether solid or contoured, memory foam and latex pillows should never be submerged in water or put in a washing machine. The intense agitation and water saturation will tear the delicate foam structure apart. These pillows require spot cleaning and manual refreshing only. Shredded memory foam pillows are an exception to this rule, as some brands allow machine washing for the fill, but you must verify this on the product care label first.
Pre-Treating Stains and Yellowing
Yellow stains are the most common issue with aging pillows. These stains are caused by urea and fatty acids present in sweat and skin oils. Standard laundry detergent alone is often not strong enough to break down these oily bonds, meaning pre-treatment is essential.
The Enzyme Pre-Treatment Method
For localized stains, create a solution using a liquid enzyme laundry detergent or a dedicated stain remover. Enzymes are specifically designed to break down organic proteins and fats. Apply the liquid directly to the yellowed areas and rub it in gently with a soft-bristled brush or a clean microfiber cloth. Allow the mixture to sit for at least fifteen to thirty minutes before moving on to the main wash cycle.
The Deep-Soak Whitening Solution
If the entire pillow has turned a dull, dingy shade of yellow, a deep soak is highly effective. Fill a large utility sink or your bathtub with hot water. Add the following ingredients to the water:
-
One cup of powder laundry detergent
-
One cup of powder dishwasher detergent
-
One cup of oxygen-based bleach alternative
-
Half a cup of baking soda
Stir the water thoroughly until all powders are completely dissolved. Submerge your pillows into the liquid, pressing them down so they become fully saturated. Let the pillows soak in this mixture for two to four hours. Flip them over halfway through the soaking time to ensure even treatment.
Machine Washing Down, Feather, and Fiberfill Pillows
Once your pillows are pre-treated, you can proceed to the washing machine. If you are using a top-loading machine with a center agitator, place two pillows into the drum vertically, one on each side of the agitator, to maintain balance. For front-loading or high-efficiency top-loading machines without an agitator, place two pillows side-by-side horizontally. Washing two pillows at once keeps the machine balanced during the high-speed spin cycle.
Step 1: Select the Right Detergent
Avoid using heavy, high-sudsing detergents. Residual soap is difficult to rinse out of dense pillow fillings and will attract dirt more quickly once dry. Opt for a mild, low-sudsing liquid detergent. If you are washing down or feather pillows, use a specialized down cleaner, which preserves the natural oils of the feathers and prevents them from becoming brittle.
Step 2: Set the Washer Cycles
Set your washing machine to the gentle or delicate cycle. Use warm water for synthetic pillows to help dissolve body oils, and use cool or warm water for down pillows to protect the feathers.
Step 3: Run an Extra Rinse and Spin
Pillows act like giant sponges. To ensure all soap residue is completely removed, program your machine to run a second rinse cycle. Follow this with an extended or high-speed spin cycle to extract as much moisture as possible before drying.
Deep Cleaning Memory Foam and Latex Pillows
Because memory foam and latex cannot go into a washing machine, you must use a hands-on approach to lift dirt and refresh the core structure.
Step 1: Vacuuming the Core
Remove the pillowcase and any protective zippered covers. Use the upholstery attachment on your vacuum cleaner to thoroughly vacuum the entire surface of the foam pillow. This removes loose dust, hair, and dead skin cells from the surface pores.
Step 2: Spot Cleaning
Mix a few drops of mild dish soap or liquid laundry detergent into a bowl of warm water until bubbles form. Dip a clean microfiber cloth into the soapy water and wring it out completely until it is just slightly damp. Gently blot any stained areas on the foam. Avoid rubbing aggressively, as this can tear the foam.
Step 3: Rinsing the Soap
Dampen a separate clean cloth with plain water, wring it out well, and wipe down the treated areas to remove the soap residue. Press a dry towel firmly against the wet spots to absorb excess moisture.
The Drying Process: Ensuring Complete Dryness
Proper drying is the most critical step in refreshing pillows. If even a small amount of moisture remains deep within the fill, mold, mildew, and bacteria will thrive, creating an unhealthy sleep environment and ruining the pillow.
Drying Down and Synthetic Pillows
Place the pillows in your clothes dryer. Add three to four clean tennis balls or wool dryer balls into the drum with the pillows. As the dryer spins, these balls will continuously beat against the pillows, breaking up clumps of wet feathers or fiberfill and restoring the original loft.
Set the dryer to low heat for synthetic pillows or air-dry/no-heat for down pillows. High heat can melt synthetic fibers and scorch natural down. Be prepared for this process to take several hours. Every thirty to forty-five minutes, pause the dryer, remove the pillows, and give them a vigorous manual shake to redistribute the filling.
Drying Memory Foam and Latex Pillows
Never place solid memory foam or latex pillows in a clothes dryer. Instead, lay the pillow flat on a clean towel in a well-ventilated room or outdoors in a shaded area. Avoid direct sunlight, as ultraviolet rays can accelerate the degradation of foam and latex. Allow the pillow to air-dry completely, which can take up to twenty-four hours depending on humidity levels.
Natural Deodorizing and Refreshing Techniques
If your pillows are clean but simply smell musty between washes, you can utilize natural deodorizing methods to freshen them up instantly.
The Baking Soda Method
Baking soda is an excellent natural odor neutralizer. Strip the pillowcases off your pillows and sprinkle a generous layer of baking soda directly onto the pillow surfaces. Let the powder sit for at least one hour to absorb ambient odors and moisture. Use your vacuum upholstery attachment to thoroughly clean the powder off the pillows.
The Sunshine and Fresh Air Flush
On a dry, breezy day, hang your pillows on a clothesline or place them on a clean outdoor table in the shade. The natural airflow will flush out trapped odors, while the outdoor air helps dissipate stubborn moisture.
Maintaining Pillow Hygiene Longer
To extend the lifespan of your pillows and keep them fresh between deep cleanings, implement these simple preventative habits.
-
Use zippered pillow protectors underneath your standard decorative pillowcases. These protectors act as a barrier against sweat, oils, and liquids.
-
Wash your pillowcases and zippered protectors once every week in hot water.
-
Fluff your pillows daily when making your bed to encourage airflow through the fibers.
-
Avoid sleeping with wet hair, as moisture seeps directly into the core filling and invites mold growth.

Frequently Asked Questions
How often should I wash my bed pillows?
Ideally, you should wash your pillows at least two to three times per year. However, if you suffer from night sweats, have chronic allergies, or allow pets to sleep on your bed, you should increase the frequency to once every two months to maintain optimal hygiene.
Can I wash memory foam pillows if they have a removable cover?
You can wash the removable zippered cover in the washing machine following its specific care instructions. However, the inner solid foam core itself must never be put through a washing machine cycle, as the mechanical agitation will break the foam apart.
Why did my pillows turn lumpy after I washed them?
Lumpiness usually happens when synthetic fiberfill pillows are dried without sufficient agitation or at a temperature that is too high. To fix this, re-wet the pillow slightly and dry it on a low-heat setting with several wool dryer balls or tennis balls to break up the fiber clumps.
How do I know when it is time to replace my pillow completely?
You can perform the fold test for synthetic and down pillows. Fold your pillow in half and hold it down for thirty seconds. Release it, and if the pillow stays folded rather than springing back to its original shape, the filling has lost its resiliency and the pillow needs to be replaced.
Is it safe to use liquid fabric softener on pillows?
No, you should avoid using liquid fabric softeners when washing pillows. Softeners leave behind a waxy chemical coating on the fibers. This coating reduces the breathability of the pillow, diminishes its natural fluffiness, and causes the fibers to clump together over time.
Can I use chlorine bleach to whiten yellowed down pillows?
It is best to avoid chlorine bleach on down and feather pillows. Chlorine bleach is a harsh chemical that strips the natural protective oils from feathers, causing them to become brittle, break down, and lose their loft. Use oxygen-based bleach alternatives instead.
What is the quickest way to dry a pillow if I do not have a dryer?
If you do not have a clothes dryer, place the pillow flat on a wire drying rack to maximize airflow underneath it. Position an electric floor fan to blow directly across the surface of the pillow, and flip the pillow over every few hours to ensure even drying.
