Terrible Herbst's staff cares for cars and the environment by swiping vehicular surfaces with eco-friendly Blue Coral products. During the ultimate full-service wash, vehicles are scoured inside and out over 20–25 minutes. Valets escort vehicles to the drive-thru tunnel, in which cars luxuriate in a bath of foam. A car caretaker then towel-dries its exterior and takes to the inside, wiping windows, dashboards, and consoles, and vacuuming dirt and Australopithecus-era crumbs from carpets. Wheels emerge from the treatment purged of dirt, and tires debut enameled in a protective dressing. The VIP express car wash with RainX cleanses cars in less than five minutes with a human-operated pre-scrub, then sends them through the underpass to bask in bubbles and a spot-free rinse.
