Terrible Herbst's automated wash tunnel and experienced staff carefully swipe vehicular surfaces clean with eco-friendly Blue Coral products. Each five-minute express exterior car wash starts off as valets escort vehicles to the drive-thru tunnel, which gently gargles cars with a triple-foam polish and clear-coat protectant. After the soft-cloth wash coats circular feet with wheel brightener, a spot-free rinse and air-dry prep vehicles to emerge onto the road as shiny and head-turning as a president with braces. Customers who opt for the Ultimate full-service car washes can augment the express exterior washes with interior-pampering services. During the 20- to 25-minute cleaning, car-caretakers wipe and dust windows, dashboards, and consoles while vacuums devour dirt and precambrian crumbs from carpets. Wheels emerge from the treatment purged of dirt, and tires debut enameled in a protective dressing.
