Here’s how to clean dirty bed pillows to leave them white and smelling sweet.

1. Check care label

Before washing your pillows, it’s crucial to carefully read the care label attached to each one. Pillow fillings vary widely—from down feathers and memory foam to synthetic fibers—and each type requires specific care to avoid damage. For example, memory foam pillows often cannot be machine washed and require spot cleaning or professional cleaning services.

Most synthetic and down-filled pillows are machine washable, but the label will specify the recommended water temperature, washing cycle, and whether bleach or fabric softeners are safe to use. Ignoring these instructions can shorten the lifespan of your pillows or cause clumping of the filling.

If your pillow’s label is missing or unclear, treat it as delicate: use cold water, a gentle cycle, and avoid harsh chemicals.

2. Remove pillowcases

Before washing the pillows themselves, always remove any pillowcases or protective covers. These are usually made of cotton or other washable fabric and can be laundered separately according to their own care instructions.

Removing pillowcases helps ensure that dirt, oils, and sweat trapped in those covers don’t redeposit onto the pillows during washing. It also allows you to wash the pillowcases more frequently to maintain overall bed hygiene.

Check pillowcases for stains and treat them with a stain remover if necessary before laundering. Wash pillowcases in warm water with a mild detergent to keep them fresh and clean.
