Here's a breakdown:
* Frank Machuca is credited with creating the first "automatic" car wash in 1946. He built a rudimentary system in Seattle, Washington, using a conveyor belt to move cars through a series of cleaning stations. This system was more of a "conveyor belt" wash than the modern automated system we know today.
* Thomas Murphy later built upon Machuca's concept, developing the first fully automated car wash in 1950. This system used a more sophisticated conveyor belt system and introduced innovations like automatic soaping, rinsing, and drying.
Therefore, while Machuca is credited with the initial concept, Murphy is often recognized for the development of the modern, fully automated car wash we see today.
It's worth noting that many other inventors and businesses contributed to the development and evolution of the car wash over time. Innovations such as the tunnel car wash, touchless car wash, and various cleaning technologies have all played a role in shaping the industry.
