What temperature kills dust mites on bedding?

Guidance often cites washing at 60°C where the item’s care label allows it. Not every duvet or pillow can take that heat. Use a washable protector and labelled-safe cycles as your practical system.

Can I put a memory foam pillow in the washing machine?

Usually no. Many foam pillows are spot-clean only. Machine washing can break foam cells. Check the label and maker care sheet.

How often should I wash sheets?

Many households wash sheets weekly. Hotter rooms, allergies or illness may mean more often. Protectors and pillowcases pick up skin oils quickly.

How to Wash Sheets, Duvets and Pillows

Entity: washing bedding pillows duvets

Layered duvet and pillows on a king bed with a tall fabric headboard — Sheets, duvet and pillows work together with the bed — not just the mattress alone.

In short

Clean bedding means following fibre care labels, not guessing. Cotton sheets usually take a warm wash. Many duvets and pillows need lower heat, gentle spin and full drying. Hot washes can help reduce dust mites when the label allows. Check the sewn-in label first. Mattress protectors are often the easiest high-wash layer in an allergy plan.

Educational care icons for washing sheets, duvet covers, pillows and protectors at labelled temperatures — The care label is the rulebook. Hot washes only help when the textile allows them.

Layer-by-layer basics

Item	Typical approach	Watch for
Sheets & pillowcases	Warm/hot wash if labelled; tumble or line dry	Shrinkage on some cottons
Duvet covers	Same as sheets	Zippers / buttons catching
Duvets	Follow fill label; often lower heat, thorough dry	Clumping if left damp
Pillows	Fibre pillows often washable; foam often not	Loss of loft if overloaded
Mattress protectors	Usually frequent wash — check waterproof membrane rules	Heat that damages coating

Allergy-friendly habits

Duvet and TOG note

Washing does not change a duvet’s TOG rating permanently if the fill recovers, but overheating or damaged baffles can ruin loft. When in doubt, use a professional cleaner listed as safe for that fill.

Common mistakes

Boiling every pillow regardless of foam cores
Leaving a damp duvet in a heap overnight
Ignoring protector care and washing the whole mattress instead
