To clean your sandwich press, you'll want first, follow the manufacturer's instructions, and make sure all removable parts are taken off. With a rag or soft brush, scrub the outside of the press where the nonstick lining is over top of the metal surface. You can also use some dish soap on this part to help get it cleaner faster. Some models include a removable plate or a removable drip tray for thorough cleaning. Be sure to also look for a non stick coating on the cooking surface to prevent tough sticking from your grilled sandwich.
