At Millbrae Express Carwash, attendants guide auto owners into their two-lane car-wash bay for soft-touch exterior or full-service car washes, including higher-tiered options that douse paint jobs and wheels with Rain-X. After their cars exit the wash tunnel, auto owners can watch from under a table umbrella as attendants clean out interiors using vacuums that are studying for their drivers' permits. When road grime reaches severe status, the shop's detailing technicians massage carnauba wax onto paint jobs, shampoo floor mats, and coat surfaces with biodegradable Blue Coral cleaning products.
