How to Wash Sheets, Duvets and Pillows

Published 2026-08-03. Last updated 2026-08-03. Desk research by Kaiser Khan — we have not product-tested washing bedding pillows duvets. This is not a shop review and not medical advice.

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.

Sheets, duvet and pillows work together with the bed — not just the mattress alone.

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

  1. Fit a washable mattress protector
  2. Wash pillowcases and sheets on the hottest safe cycle for that fabric
  3. Dry completely — mites like moisture
  4. See dust mites ecology for the wider system

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

How it works

The care label is the rulebook. Hot washes only help when the textile allows them.

Frequently asked questions

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.
