How Often to Wash or Replace Your Pillow
Wash pillowcases weekly, follow fill-specific care instructions, and replace a pillow when cleaning or adjustment no longer helps.
Wash your pillowcase weekly as a practical starting point, and clean the pillow itself according to its care label. There's no single washing or replacement schedule for every pillow. The fill, its condition, and the manufacturer's instructions all matter.
Three things to remember
- Check each care label before washing.
- Keep buckwheat hulls dry and wash the cover separately.
- Judge a pillow by its condition, not just its age.
A stale case doesn't necessarily mean the pillow underneath needs replacing. An uneven pillow may only need its fill redistributed, if its design allows it. Check the layers separately before deciding what to clean or replace.
A practical pillow care schedule
Use this as a starting routine, not a rule for every pillow. The care label comes first, whether you're cleaning the case or deciding what to do with the pillow inside.
| When | What to do |
|---|---|
| Weekly | Wash the pillowcase according to its care label. |
| Monthly | Remove the covers and check the pillow for odors, damage, or a shape that no longer feels comfortable. |
| As directed | Clean the protector and pillow, following the separate instructions for each. |
| When needed | Adjust or clean the pillow if its instructions allow it. Consider replacing it if it's still damaged or uncomfortable. |
For memory foam, cleaning expert Scott Schrader suggests cleaning about every three to four months, with spot cleaning when needed. Check your particular pillow before adopting that interval. Some foam pillows may permit spot cleaning only.
Wash the right layer
The pillowcase catches some everyday buildup, but body oils and other residue can still reach the pillow underneath. At your next bedding change, take a look beneath the case rather than assuming both layers need the same care.
Thing is, a case, a separate protector, and the pillow's own shell may all have different instructions. A washable cover isn't permission to wash the whole pillow. Read each label separately, and let every cleaned layer dry fully before putting it back together.
How to clean memory foam
Keep memory foam out of the washing machine unless the pillow's instructions say otherwise. The laundry experts interviewed here say machine agitation can damage it.
Look at the label before choosing a cleaning method. It should tell you whether hand-washing is permitted or whether the foam needs spot cleaning only. If there's a removable cover, follow its instructions separately. Both the cover and foam need to be thoroughly dry before you put them back together.
How to care for buckwheat hulls
Buckwheat hulls need to stay dry. Don't wash the hulls or put a filled buckwheat pillow in the washer.
If the cover is removable and its label permits washing, empty the hulls into a clean, dry container first. Then wash the cover as directed and let it dry fully before refilling it. Husband Pillow's cleaning guide also suggests airing the hulls on a dry tray in a dry, airy place.
When should you replace your pillow?
There's no single replacement interval established for every pillow. Age can prompt a closer look, but check the pillow's shape and condition too. Notice how it feels after any cleaning or adjustment its manufacturer permits.
| What you notice | Try this first | When to consider replacing |
|---|---|---|
| A stale pillowcase | Wash the case, then check the layer underneath. | A stale case alone isn't a reason to replace the pillow. |
| Lumpy or uneven fill | Redistribute the fill if the pillow is designed for adjustment. | It remains uncomfortable after adjustment or permitted cleaning. |
| A persistent odor | Clean the appropriate layers as directed, then dry them fully. | The odor remains after appropriate cleaning and thorough drying. |
| Tearing or crumbling foam | Check the manufacturer's instructions before handling it further. | The material is breaking down. |
With an adjustable buckwheat hull pillow, check the cover and fill separately. Depending on their condition, you may not need to replace every part. The useful check is what needs attention now, not the pillow's age alone.
Avoid common laundry-day mistakes
A washable cover and a washable pillow aren't necessarily the same thing. Check the pillow's label before putting it in the washer, and don't guess at a dryer setting. Machine agitation or heat can damage some fills, even when their covers can be washed.
A damp pillow needs attention before you use it again. If it stays damp or develops visible mold, don't cover it up and carry on. Follow the manufacturer's instructions. Replace the pillow if it can't be cleaned and dried as directed.
Pillow washing and replacement FAQ
How often should I wash my pillowcase?
Weekly is a practical place to start. Follow the case's care label, and wash it sooner if it needs freshening.
Can I put my pillow in the washing machine?
Only if the pillow's own instructions say you can. A machine-washable case or protector doesn't necessarily mean the pillow inside can go in too.
Does a stain mean I need a new pillow?
Not necessarily. Follow the label's cleaning directions, let the pillow dry fully, and then check its condition.
Can I wash a buckwheat pillow?
Keep the hulls dry. If the fabric cover is removable and its instructions permit washing, take the hulls out first. Let the cover dry fully before refilling it.
The bottom line
At your next bedding change, check the label and take a look at the pillow underneath the case. Clean each layer as directed and adjust the fill if the design allows it. If the pillow remains damaged or uncomfortable after those steps, consider replacing it.
