The computer-driven wash tunnel at Carisma Wash scours vehicles in four minutes or fewer, but that doesn't mean cutting corners. In fact, during the brief cycles, a parade of mild, wet, and grease-cutting soaps coat the body, tires, and windows of cars four times or as many as it takes to remove hitchhikers from the roof rack. Wheels covered with soft cloth gently scrub grime while passengers stay comfortably seated inside.

Washes range from the basic Touch It Up to The Ultimate, which encompasses everything from UV protectant to an undercarriage scrub. After an air dry, customers emerge and grab self-service vacuums to free interiors of crumbs and nephews who fell between the seats. Employees stand by their handiwork, granting patrons a free wash if they're not satisfied after their first spin.
