The PrimeWash
Double Difference
Most car washes give you one pass and call it done. At PrimeWash Express, we give you double.
Serving Upland, Ontario, and the Inland Empire, PrimeWash Express is the only drive-thru car wash in the area to offer the PrimeWash Double Difference — a premium wash process built around doing everything twice, so nothing gets missed.
From your first pull-in to your final shine, you get: a Dual Conveyor Belt System for smooth, wheel-safe handling, a Double High-Pressure Rinse that blasts dirt before brushes ever touch your car, Double Combo Brushes engineered to reach every curve and corner, Double Drying with powerful blowers and soft shammy cloths for a streak-free finish, and an exclusive Double Tunnel Experience — the first of its kind in California — where a dedicated second tunnel applies express wax and polish for lasting protection and a high-gloss shine.
This isn't just a car wash. It's a complete vehicle care system — and there's nothing else like it in the Inland Empire.

How Our Double Tunnel Works
Tunnel 1:
Wash Process
At PrimeWash Express, we offer double the high-pressure water rinses, double the combo brushes, and double the drying for a superior car wash experience.
Our wash tunnel features blowers and an additional buff 'n dry soft cloth combo unit to remove any excess water.
Choose PrimeWash Express for meticulous care and the Premium Plus experience.
Tunnel 2:
Wax-N-Polish Process
PrimeWash was a pioneer in introducing the double tunnel process to California.
Our top package includes a second tunnel dedicated to express waxing and polishing after the initial wash and drying. In this unique process, vehicles go through a separate queue where employees apply an express wax, enhancing the paint's shine and adding a protective layer. The vehicle then moves onto a conveyor belt in the polish tunnel, where buffing brushes evenly apply the express wax. Frequent use of the polish tunnel builds up a protective layer, making your car's paint softer to the touch and better shielded from environmental elements.
Experience our DOUBLE TUNNEL at our Upland and soon-to-be Chino Hills locations for the ultimate in car care.
