For dishwasher-safe finishes, all parts of the Rotera are top-rack dishwasher 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 as any dirt marks on it, a magic eraser will remove them.
To know if your Rotera is dishwasher safe, it will say so on the product landing page (near the "Add to Bag" button), as well as on the base of the product itself.
