Pomona Express Car Wash
Vehicles enter the car-wash tunnel at Pomona Express Car Wash and emerge with a near-factory-issue gleam. Best of all, each car wash can take as little as five minutes, meaning customers often find time to sneak in a wash during their lunch breaks. The tunnel blasts dirt from wheels with a high-pressure washer, and optional wax applications keep cars shiny, even when they've angered the rain gods.
