How Often Should You Wash a Mattress Protector?

There is no single schedule for every household. A protector under clean sheets usually needs less frequent washing than the sheets themselves, but accidents should trigger immediate laundering.

Routine use

Periodic washing is usually more practical than washing it at every sheet change when the protector remains clean and dry.
