Unplug your Ninja Woodfire Electric BBQ Grill and let the appliance and accessories cool before cleaning. Soak the grill plate and crisper basket to remove any food residue, then hand wash in warm, soapy water. Remove the smoke box and safely discard cooled ash contents after every use. Carefully remove the cooled grease tray from the unit, safely discard grease contents and then hand wash in warm, soapy water. Never use abrasive tools or cleaners. The pellet scoop is dishwasher safe. The inner lid can be gently wiped down with a damp towel or cloth.
