quotes and I couldn't pass this one up.
History of the Car Wash.
The first concept of an assembly-line vehicle wash system was developed in the Detroit area in 1914. It was called "The Automobile Laundry" and used manpower to push vehicles from one wash station to the next in a circular fashion. By 1928, a drive-through type tunnel with a man-powered chain conveyor moved the automobiles through the car wash, and car wash automation was born.
