Prime Shine Car Wash opened its first location in Modesto on North McHenry Avenue on April 11, 1991. What started then as a single-location car wash founded with the goal of changing the way Californians think about washing their cars has grown to become California’s largest independently owned car wash chain. Prime Shine was the first of its kind in the state, serving customers looking for a high-quality wash, at a reasonable price, with friendly and professional staff. With a top-to-bottom clean that is value-priced, and finished in just three minutes, Prime Shine filled the niche between time consuming and pricey full-service washes, and the do-it-yourself option. Since opening Prime Shine Car Wash in 1991, owners Norm and Evan Porges have been the driving force behind the company that has washed millions of vehicles throughout the Central Valley. With 17 locations to serve you, you're never far from a clean car!
