Before learning how to clean pillows, check that yours still provides support. Washing can remove sweat, body oils and surface marks, but it cannot restore a pillow that has flattened or lost its shape.
Check if your pillow is still worth washing
Fold the pillow in half, hold it for 30 seconds and let go. If it stays folded rather than springing back, it has lost its support and washing will not restore it.
Other signs include permanent lumps, flattening that does not recover, morning neck pain and worsening night-time allergies. If neck pain continues after replacing your pillow, the Healthy Sleep Partnership Program can connect you with guidance from health professionals.
You can also find the right pillow for how you sleep using the Perfect Pillow Finder.
How to wash pillows by fill type
Most polyester, cotton, down and feather pillows can go in a washing machine on a gentle cycle, but the right water temperature depends on the filling.
Online advice varies because different fills need different care. Check the care label first, then use this guidance.

Remove the pillowcase and protector first. Use mild liquid detergent, skip bleach and fabric softener and run an extra rinse. Washing two pillows together can help balance the drum. Dry each pillow completely, as moisture left inside the filling can lead to mould.
How often should you replace your pillow?
Most pillows need replacing every one to two years, though the useful life varies by fill and regular condition checks matter more than one general rule.

Protect your pillow with Mattress and Pillow Science pillow protectors
Cleaning can refresh a supportive pillow, but it cannot restore one that has lost its shape. A pillow protector helps keep sweat, skin oils and dust away from the filling so the pillow stays cleaner for longer.
