Self-Cleaning Public Restrooms

  Ever been to a carwash where your car was washed, waxed, AND DRIED without a human hand touched the car. Same principle....
  The walls (and if necessary, the ceiling) of the bathroom would be waterproof. There would be waterjets in the ceiling and the walls. At the push of a button, the water jets would wet the place down, then send out deodorizing and bacteria-fighting soap, then a rinse down that sent everything down the drains in the floor, then a blow-dry from ceiling fans, etc. Finally, a light misting of some fresh smell.
