Your husband is likely right about the salt screwing with the electronics. I can see where running hot would "solve" the problem or help. Salt's conduct electricity and so as you get a layer of salt built up in a device is bound to have a higher and higher chance of acting wonkie. On a side note, any device you can break down your self and rebuild, should hold out well to getting whipped down with alcohol prep pads. I've cleaned out I have no clue how many game pads and restored them to perfect working order after something got built up on the circuit board.
