When Jesus said Peter had no part with him unless washed, what did Peter ask him to wash too?

Answer: His hands and head

Peter first refused, then said, "Not only my feet, but my hands and my head as well!"

““Never shall You wash my feet!” Peter told Him. Jesus answered, “Unless I wash you, you have no part with Me.” “Then, Lord,” Simon Peter replied, “not only my feet, but my hands and my head as well!””— John 13:8-9 (BSB)
