A George Foreman grill needs to be thoroughly cleaned after each use to maintain good condition. Unplugging the grill and letting it cool down before attempting to clean it is essential for safety reasons.
If the George Foreman grill has a temperature probe and grill base, the cleaner of the grill should remove both, and clean them with a damp cloth. The drip tray and the grill plate should be washed with warm, soapy water before wiping them dry.
The appliance owner should never use steel wool, metallic sponges or any abrasive solutions on the grill. The best items to use are nylon scrubbing pads.
