The Orange Pride Car Wash has been the most affordable car wash in Stillwater, Oklahoma for some forty years. Originally there were four Orange Prides, now only one is left, but keeping these last ten wash bays open and running is sometimes a bit of a challenge. Self Service Car Washes seem simple enough on the outside, put in the quarters, select a function and wash your vehicle. As long as everything is working we don't think much about how it works. But, the part you don't see from the outside, the components that makes it work, can be confusing when seen from the inside. This book attempts to explain the components, functions, maintenance and repair of a Self Service Car Wash. By breaking down the various parts and pieces that make up the necessary equipment, and explaining the interaction of that equipment so that out in the Wash Bay you can push a button and wash.
