How To Wash And Care For Pillows Properly

If you’re anything like me, you’re brilliant at washing pillowcases… and far less brilliant at remembering the actual pillows underneath.

But pillows quietly collect sweat, skin oils, dust and allergens over time, and giving them proper care can help them stay fresher, last longer and feel nicer to sleep on.

Cleaning advice depends on what’s inside your pillow, so the first job is working out what you’ve got.

A Quick Rule Before You Start

Always check the care label first. If it gives specific temperature or drying instructions, follow those over any general guide. If your pillow is torn, leaking filling, or has foam that’s crumbling, it’s probably past saving and better replaced.

How Often Should You Wash Pillows

A common recommendation from cleaning and sleep guidance sources is washing washable pillows around every three to six months, with pillowcases washed weekly and protectors washed regularly too.

The short version: if you’ve had illness in the house, there’s a noticeable smell, you’ve got allergy flare-ups, or the pillow is visibly marked, don’t wait for your “schedule”.

Before Washing Any Washable Pillow

Pillows in Washing Machine

  1. Use A Pillow Protector
    Once your pillow is clean, a zippered protector is the easiest way to keep it that way. It also reduces how much sweat and drool (lovely) reaches the pillow itself.
  2. Spot-Treat Stains
    Dab (don’t scrub) with a mild detergent and water. Let it sit briefly, then blot again with clean water.
  3. Wash Two At A Time
    If you’re machine-washing, doing two pillows together helps balance the drum.
  4. Use A Gentle Detergent And Less Than You Think
    Too much detergent can leave residue inside the pillow, which can make it feel clumpy or stiff after drying.

Down And Feather Pillows

Most down and feather pillows are machine-washable, but they need gentle handling.

How To Wash

Use a delicate cycle with cool or warm water, and a mild detergent. An extra rinse is helpful to clear out soap trapped in the filling.

How To Dry

Drying matters as much as washing. Use low heat and expect it to take a while. Add dryer balls (or clean tennis balls) to help break up clumps and restore fluff. Keep checking that the pillow is fully dry all the way through, because damp feathers can smell and potentially develop mildew.

Top Tip

If your down pillow has any tears or weak seams, don’t machine wash it. Feathers escaping into your washing machine is a level of chaos no one needs.

Synthetic And Polyester (Microfibre) Pillows

These are usually the easiest. They’re commonly machine-washable and dry faster than natural fills.

How To Wash

Use a gentle cycle with warm (or cool) water and mild detergent. If the pillow is very sweaty or yellowed, you can run a second rinse.

How To Dry

Low to medium heat is typically fine if the label allows tumble drying. Make sure it’s completely dry to prevent that musty “been left in the washing machine overnight” smell.

Memory Foam Pillows

Memory Foam pillows

This is the one that catches people out: many memory foam pillows should not go in the washing machine, and they also shouldn’t be soaked. Foam dries slowly, which raises the risk of trapped moisture and damage.

What To Do Instead

  • Vacuum: Use the upholstery attachment to lift dust and debris.
  • Spot clean: Dab stains with a mild detergent solution, then blot with clean water.
  • Air dry thoroughly: Leave it somewhere warm and well-ventilated, out of direct heat.

Important Note

Some memory foam pillows have removable, washable covers. If yours does, wash the cover as directed and focus on spot-cleaning the foam insert.

Latex Foam Pillows

Latex is also generally treated as “do not machine wash” unless the manufacturer says otherwise. Like memory foam, it can be damaged by agitation and slow drying.

Care Routine

Vacuum regularly, spot-clean small marks, and let it fully air dry. If you use a protector and wash that often, latex pillows tend to stay in decent shape.

Wool Pillows

Wool is brilliant for temperature regulation, but it needs a gentler approach. Some wool pillows are washable, others have washable covers with removable filling, and some are strictly spot-clean only.

If Yours Is Washable

Use cool water, a wool-safe detergent, and a gentle/wool cycle, then avoid tumble drying unless the label explicitly allows it. Many wool care guides recommend air drying to protect the fibres.

Everyday Care

Wool often benefits from regular airing. A few hours in fresh air can help keep it smelling clean between proper washes.

Buckwheat Hull Pillows

Buckwheat pillows are very much a “separate the parts” situation. You usually wash the outer cover and care for the hulls separately.

How To Clean

Remove the hulls into a clean container. Wash the fabric case as the label allows (often machine washable). For the hulls, many buckwheat pillow makers recommend airing them out and drying them thoroughly (some suggest sunning them for a few hours) rather than washing them with water.

Why So Fussy

If hulls get damp and stay damp, they can smell and degrade. Keep them dry.

What About Bamboo, Kapok, And “Cooling Gel” Pillows

Cool Gel Pillow

A lot of pillows marketed as bamboo are actually bamboo-derived fabric covers over polyester or foam fills.

“Cooling gel” is often a layer or insert combined with foam. In both cases, treat them based on what the filling is, not the marketing label: washable synthetic fills can usually be machine-washed, while foam-based pillows typically need spot-cleaning.

When in doubt, follow the label and wash the removable cover only.

Drying And Storage Basics That Matter More Than You’d Think

Make sure pillows are completely dry before putting them back on the bed. Any lingering dampness can lead to odours and mildew.

Fluff pillows daily (just a quick shake) and try not to sleep on a pillow that’s still slightly damp from a “quick refresh”.

A Cleaner Pillow, A Better Night

Clean pillows aren’t about being perfect or turning your laundry routine into a second job.

It’s just one of those small, satisfying resets that makes bedtime feel nicer, helps keep things hygienic, and can stop pillows getting gross long before their time.

Work out what type you’ve got, follow the label, and build a simple rhythm: protect, wash when you can, spot-clean when you can’t, and dry properly every single time.
