Turn off and unplug the fryer, allowing it to cool completely. Remove the oil and dispose of it properly or filter it for reuse. Disassemble the fryer and wash the oil tank, basket, and other removable parts with warm, soapy water. Wipe the heating element and exterior of the fryer with a damp cloth. Do not immerse the heating element in water. Ensure all parts are completely dry before reassembling.
