Thanks for all the ideas. My first step was to call my daughter, she has three teen-age boys. Aaron, 12, answered the phone. He said, "put it in a bowl of dry rice."
Later I talked to my wife, she's out of town. She told me she had run one of her ipods through the washer and it works fine now.
The ipod is sitting in a bowl of rice now. I'll plug it in in a few days.
