Most household pillows can go straight into your washing machine, but the answer depends on the pillow type and your machine capacity. Washing pillows at home saves money and removes dust mites, sweat, oils, and allergens that build up over months of nightly use.
This guide explains which pillows you can safely machine wash, how to prepare and wash them correctly, what settings and detergents work best, and how to dry pillows without damage or mildew.
Can You Wash Pillows in a Washing Machine?
Yes, you can wash most pillows in a washing machine, including those filled with polyester, down, and feathers. Memory foam and latex pillows cannot go in the washer and require spot cleaning only. Always check the care label first, as some pillows have special coatings or construction that makes machine washing unsafe.
Which Pillow Types Are Machine Washable
The fill material determines whether a pillow can survive a wash cycle. Knowing what is inside your pillow helps you avoid expensive mistakes.
Down and Feather Pillows
Down and feather pillows wash well in machines as long as you use gentle cycles and low heat. The natural oils in feathers can withstand water, and washing actually restores loft when done correctly.
Make sure your machine has enough space for the pillow to move freely. A cramped drum can prevent proper rinsing and leave detergent residue that clumps the fill.
Polyester and Fiberfill Pillows
Synthetic pillows are the easiest to wash at home. Polyester fill holds up to repeated washing and dries faster than down.
These pillows are also budget-friendly to replace if washing does not restore their support. Most polyester pillows benefit from washing every three to six months.
Memory Foam and Latex Pillows
Never put memory foam or latex pillows in a washing machine. The agitation tears the foam, and water saturation destroys the structure.
Instead, spot-clean stains with a damp cloth and mild detergent, then air out the pillow in a well-ventilated space. Remove and wash the pillow cover regularly to keep the surface clean.
Buckwheat and Other Alternative Fill Pillows
Pillows filled with buckwheat hulls, millet, or similar materials should not be machine washed. The hulls absorb water, become moldy, and lose their shape.
Empty the fill into a container, wash the outer cover, and air the hulls in direct sunlight to refresh them naturally. Replace hulls if they develop an odor or break down.
How to Prepare Pillows for Washing
Proper preparation prevents damage and ensures your pillows come out clean. A few minutes of checking saves you from ruined bedding.
Check the Care Label
Every pillow sold in recent years should have a sewn-in tag with washing instructions. Follow any temperature limits, cycle recommendations, or warnings listed.
If the label says “dry clean only,” do not attempt machine washing. Professional cleaning uses different solvents that protect delicate fills.
Inspect for Damage
Look for rips, loose seams, or worn fabric before washing. Repair any holes or weak spots to prevent fill from escaping into your machine.
A small tear can become a large opening during the spin cycle. Use a needle and thread or fabric patch to reinforce damaged areas.
Remove Pillowcases and Protectors
Strip off all removable covers and wash them separately. Pillow protectors and pillowcases need different wash settings than the pillow itself.
Washing covers alone also lets you clean pillows less frequently, extending their lifespan. Most covers can tolerate hotter water and stronger detergents than pillow fills.
Step-by-Step Washing Instructions
Following the correct sequence and settings protects your pillows and gets them thoroughly clean. Rushing through or skipping steps leads to lumpy, smelly, or damaged results.
Load the Washing Machine Properly
Wash two pillows at once to balance the load and prevent the machine from going off-balance during the spin cycle. Place them on opposite sides of the drum.
If you only have one pillow to wash, add a couple of bath towels to balance the weight. An unbalanced load can damage both your pillows and your washer.
Choose the Right Detergent
Use a small amount of mild liquid detergent without dyes or heavy fragrances. Powder detergents can leave residue in dense pillow fills.
For down and feather pillows, consider a detergent designed for delicate fabrics or down items. Regular detergent can strip natural oils and reduce loft over time.
Select the Correct Cycle and Temperature
Set your machine to a gentle or delicate cycle with warm or cool water. Hot water can break down adhesives in some pillow construction and damage certain fills.
Add an extra rinse cycle to remove all detergent. Soap residue attracts dirt and can cause clumping in fiberfill or down.
Consider an Extra Spin
After the rinse cycle completes, run an additional spin cycle to remove as much water as possible. Pillows hold a lot of moisture, and excess water extends drying time.
This step is especially important for down and feather pillows, which can take many hours to dry completely. The more water you remove in the washer, the less time you spend drying.
How to Dry Pillows Without Damage
Drying is just as important as washing. Pillows that stay damp develop mildew, odors, and lose their structure.
Machine Drying
Most washable pillows can go in the dryer on a low or no-heat setting. High heat can melt synthetic fills, scorch feathers, or shrink pillow covers.
Add two or three clean tennis balls or dryer balls to the drum. They bounce against the pillow and break up clumps, helping fill redistribute evenly.
Drying Time and Checking
Plan for at least two to three hours of drying time, depending on pillow size and fill. Check the pillow every 30 minutes and fluff it by hand.
Make sure the pillow is completely dry before putting it back on your bed. Squeeze the center and corners to feel for any remaining dampness.
Air Drying
You can air dry pillows outdoors on a sunny, breezy day. Lay the pillow flat on a clean surface or hang it on a clothesline.
Turn the pillow every few hours to expose all sides to air. This method takes longer but uses no energy and works well for pillows that cannot tolerate heat.
Common Mistakes to Avoid
A few missteps can ruin a pillow that would otherwise last for years. Knowing what not to do is just as valuable as the correct method.
Using Too Much Detergent
Excess detergent does not make pillows cleaner. It leaves residue that is difficult to rinse out and can cause skin irritation.
Start with half the amount you would use for a regular load of laundry. You can always wash again, but you cannot easily remove built-up soap.
Skipping the Rinse Cycle
One rinse is rarely enough for thick pillow fills. Soap trapped inside the pillow attracts dirt and creates a sticky texture.
Always select the extra rinse option if your machine has one. The additional water cycle takes only a few more minutes.
Putting Pillows Away Damp
Even slightly damp pillows grow mold and mildew within days. The smell is difficult to remove, and the pillow becomes unsafe to use.
If you are unsure whether a pillow is dry, give it another 30 minutes in the dryer or another day in the sun. Patience prevents waste.
How Often Should You Wash Pillows
Washing frequency depends on whether you use pillow protectors and how much you sweat at night. Most experts recommend washing pillows every three to six months.
If you have allergies, asthma, or sensitive skin, wash pillows more often to reduce dust mite populations and allergen buildup. Weekly washing of pillowcases helps extend the time between pillow washes.
When to Replace Instead of Wash
Washing refreshes pillows, but it cannot restore support that has broken down. If your pillow stays flat after washing or develops permanent lumps, it is time to replace it.
A simple test is to fold the pillow in half. If it stays folded instead of springing back, the fill has lost its resilience and no amount of washing will fix it.
Washing Pillows in Top-Load vs. Front-Load Machines
Both machine types can wash pillows, but they require slightly different approaches. Top-loaders with agitators can be rough on delicate fills, so choose the gentlest cycle available.
Front-load washers are generally better for pillows because they tumble rather than twist. They also use less water, but make sure to add the extra rinse to compensate.
Special Considerations for Down Pillows
Down pillows need extra care to maintain their loft and warmth. Use cool or warm water, never hot, and avoid fabric softeners that coat the feathers.
Dry down pillows thoroughly on low heat with dryer balls, checking frequently to break up any clumps. Incomplete drying ruins down and creates a permanent musty smell.
Maintaining Clean Pillows Between Washes
Pillow protectors create a barrier between your pillow and body oils, sweat, and skin cells. Wash protectors monthly and pillowcases weekly to keep pillows fresher longer.
Air out pillows every few weeks by hanging them outside or placing them in front of a fan. Fresh air helps dissipate odors and moisture.
Final Thoughts
Washing pillows in your machine is a straightforward task that improves sleep quality and extends the life of your bedding. Check the fill type, follow the correct cycle and temperature settings, and dry pillows completely to avoid mold and damage.
Start by reading your pillow care labels today, then schedule a wash day every few months. Clean pillows make a noticeable difference in comfort and freshness every night.
