For optimal performance and longevity, it is recommended to hand-wash the KitchenAid W10451466/KFP13ESL Food Processor Adjustable Slicing Disc with warm, soapy water after each use. Avoid placing it in the dishwasher, as this may damage the disc or affect its adjustability over time. Gently dry the disc and store it in a safe place until your next culinary adventure.
