At Skyview Carwash, robotic washers and old-fashioned elbow grease collide to restore cars to a showroom shine. Vehicles zip through the sudsy tunnel for a thorough exterior wash and rinse, including spritzes of Blue Coral undersealant and triple coat and helpings of Rain-X protectant. Once exteriors are clean and shiny, car-wash attendants groom interiors by vacuuming up dirt, clearing smudges from windows, and donating old pine-tree air fresheners to the deprived lumberjacks of the world.
