If your Rotera is dishwasher safe, it will say it on the product landing page (near the add-to-cart button), as well as on the base of the product itself. For dishwasher-safe finishes, all parts of the Rotera are top-rack safe except for the lid. It is recommended that you hand wash the lid with warm soapy water and towel/air dry. If your sleeve has any dirt marks on it, a magic eraser will remove them.
