Most washable bed pillows should be cleaned every three to six months. Wash them sooner after spills, heavy sweating, illness, or frequent contact with pets. Pillowcases need washing much more often, usually with your sheets.
The right schedule also depends on the pillow filling. Polyester, down, foam, and latex pillows do not all have the same care needs. Always check the care label before washing, drying, bleaching, ironing, or using heat.
A Simple Pillow-Washing Schedule
Use this schedule as a practical starting point:
| Bedding item | General washing schedule |
|---|---|
| Pillowcase | About once a week |
| Pillow protector | Every two to four weeks |
| Washable sleeping pillow | Every three to six months |
| Guest-room pillow | After several guests or before long storage |
| Decorative pillow cover | Every one to three months |
| Pillow insert that cannot be washed | Spot clean as needed |
You may need to wash a pillow more often when:
- Someone regularly sleeps with wet hair.
- The pillow collects pet hair or dirt.
- Food or drinks are used in bed.
- The room is warm and the sleeper sweats heavily.
- The pillow has a visible stain or unpleasant smell.
- A child has had an accident or spill.
Frequent washing is not always better. Some fillings can flatten, clump, crack, or take a long time to dry. A washable pillow protector can reduce how often the entire pillow needs cleaning.
How Often to Wash Different Pillow Types
Polyester Pillows
Many polyester-filled pillows can be machine washed every three to six months. Polyester fill is the soft synthetic material inside many everyday pillows.
Use a gentle cycle if the care label allows it. Washing two pillows together can help balance a top-loading washer. Do not force large pillows into a small machine.
Polyester pillows may become lumpy after repeated washing. Replace the pillow when the fill no longer spreads evenly or the pillow cannot regain its shape.
Down and Feather Pillows
Many down and feather pillows are washable, but the care label should guide you. Down is the soft layer found under a bird’s outer feathers. Feather pillows contain larger feathers and may feel firmer.
These pillows may only need a full wash once or twice a year when they are protected by clean pillowcases and pillow protectors. Use a mild detergent and rinse well. Too much detergent can be hard to remove from the filling.
Dry the pillow completely on the setting allowed by the label. Down and feather fillings can hold moisture deep inside, even when the outer fabric feels dry.
Memory Foam Pillows
Most solid memory foam pillows should not go into a washing machine. The movement and water can damage the foam.
Instead, wash the removable cover on its recommended schedule. Spot clean the foam with a small amount of mild cleaning solution if the manufacturer allows it. Avoid soaking the pillow.
Shredded memory foam pillows may have different instructions. Some have washable covers but non-washable fill. Check the current product guidance before opening or washing the pillow.
Latex Pillows
Solid latex pillows are usually not machine washable. A washer can tear or weaken the material.
Wash the removable cover as directed. Spot clean the pillow only when the care instructions allow it. Keep it away from high dryer heat and direct heat sources.
Buckwheat and Other Loose-Fill Pillows
Loose buckwheat hulls should normally be removed before the fabric shell is washed. The hulls themselves should not be soaked unless the manufacturer clearly says otherwise.
Other adjustable pillows may contain small foam pieces, fibers, or mixed materials. Read the product instructions before removing the fill. Loose material can make a mess and may damage a washer.
Decorative Pillows
Decorative pillows do not collect as much sweat as sleeping pillows, but they still gather dust, pet hair, and skin oils.
Wash removable covers every one to three months, or sooner when they look dirty. Spot clean inserts that are not washable. Pillows kept on a guest bed may need cleaning before visitors arrive, especially after sitting unused for a long time.
Wash the Pillowcase More Often Than the Pillow
A pillowcase sits directly against the face and hair. It collects oils, sweat, hair products, and dust faster than the pillow inside.
Wash pillowcases about once a week with the rest of the sheets. People who sweat heavily, share the bed with pets, or use many hair and skin products may prefer to change them more often.
Keep two or three sets of pillowcases for each bed. This makes it easier to change them even when laundry day is delayed.
Most washable bed pillows should be cleaned every three to six months; learn the fastest safe way to dry a pillow by checking fill, care labels, spin extraction, dryer space, heat, airflow, turning, and hidden moisture.
Use a Pillow Protector
A pillow protector fits between the pillow and pillowcase. It often closes with a zipper and helps keep everyday dirt away from the pillow filling.
Wash the protector every two to four weeks, depending on use and its care label. A protector is especially useful for:
- Kids’ beds
- Dorm beds
- Guest-room pillows
- Pet-friendly homes
- Pillows that are difficult to wash
- Pillows that take a long time to dry
A protector does not make a pillow maintenance-free. The pillow may still need occasional washing, spot cleaning, airing, or replacement.
Measure thick pillows before buying protectors. A standard protector may pull tightly across a high-loft pillow. Loft means the pillow’s height and fullness.
How to Wash a Machine-Washable Pillow
Check the care label first. Then follow these basic steps when machine washing is allowed:
- Remove the pillowcase and protector.
- Look for holes or weak seams.
- Treat small stains according to the care instructions.
- Place the pillow in the washer without packing it tightly.
- Use a small amount of mild detergent.
- Choose the water temperature and cycle listed on the label.
- Add an extra rinse when needed to remove detergent.
- Dry the pillow using the approved setting.
- Make sure the center is fully dry before putting it back on the bed.
Large pillows may need a high-capacity washer. A tightly packed home washer may not rinse the pillow well. It can also leave the filling uneven.
Drying Pillows Properly
Drying can take longer than washing. Thick filling may stay damp in the center.
Use low heat or no heat only when the care label allows it. Stop the dryer from time to time and separate any clumps with your hands. Dryer balls may help move the filling around, but check the manufacturer’s advice first.
Foam and latex pillows should not be placed in a dryer unless the label clearly permits it. High heat can damage these materials.
Do not cover or use a pillow while it is still damp. Let it finish drying in a well-ventilated area.
When to Wash a Pillow Sooner
Do not wait for the regular cleaning date after:
- A drink spills on the pillow.
- A child or pet has an accident.
- The pillow becomes visibly dirty.
- It develops a stale or damp smell.
- Hair oil or skin products soak through the case.
- The pillow is stored in a dusty or humid space.
Clean the pillow using the method approved for its filling. When the pillow cannot be washed, spot cleaning or replacing it may be the safer practical choice.
When Washing Is Not Enough
Cleaning cannot restore a pillow that has lost its support or structure. Consider replacing it when:
- It stays flat after fluffing.
- The filling has large, firm clumps.
- Foam is cracking or crumbling.
- Feathers regularly poke through the cover.
- The fabric has holes or weak seams.
- Stains or odors remain after proper cleaning.
- The pillow no longer feels comfortable for the sleeper.
There is no single replacement date for every pillow. Use its condition, filling, care history, and comfort as the guide.
Tips for Keeping Pillows Cleaner
Use a pillowcase and washable protector on each sleeping pillow. Change the pillowcase with the sheets, and wash the protector regularly.
Keep pets on top of a washable blanket when possible. This is easier to clean than a large pillow. Avoid placing pillows directly on the floor, especially in dorm rooms and small bedrooms.
Air out guest-room pillows before visitors arrive. When storing seasonal bedding, clean and fully dry the pillows first. Store them in a dry place without crushing foam or tightly compressing delicate fill.
Frequently Asked Questions
Can I wash my pillows every month?
Some washable pillows can handle monthly cleaning, but frequent washing may wear out the fabric or filling faster. A pillowcase and protector usually allow the pillow itself to be washed less often. Follow the care label.
How often should pillowcases be washed?
Pillowcases should usually be washed about once a week. Wash them more often when they become sweaty, oily, stained, or covered in pet hair.
How often should pillow protectors be washed?
Wash pillow protectors every two to four weeks, or according to the care label. Clean them sooner after spills or heavy sweating.
Can memory foam pillows be put in the washing machine?
Most solid memory foam pillows should not be machine washed. Wash the removable cover and spot clean the foam only as directed by the manufacturer.
Can pillows go in the dryer?
Some polyester, down, and feather pillows can go in a dryer. Foam and latex pillows usually cannot. Always follow the care label and make sure the pillow is fully dry before use.
Should guest-room pillows be washed after every guest?
The pillowcase should be washed after every guest. The pillow itself may not need a full wash each time when it has a clean protector and no stains or odors. Wash the protector and inspect the pillow between guests.
How do I know when a pillow is fully dry?
Check the center, seams, and thickest areas for cool or damp spots. Press and smell the pillow before covering it. Continue drying or airing it when any moisture remains.
