In a Minit
1958
The old conveyor car wash places had long tunnel-like buildings for customers or attendants to drive through. The design used a variety overhead sprinklers and manually operated brushes. In the early 1940s, there were probably 30 of these drive-thrus in America. After the World War II a semiautomatic system that hooked to car bumpers and pulled them along tracks was introduced. Cars ere washed and rinsed in under ten minutes.A big air blower helped to dry. In the Twin Cities, Minit Car Wash was king. Location! Location! Location! The back of this postcard invited customers to take advantage of 4 perfect car washes for five bucks.
