The Solar Car Wash location in Pinole is one of eight in the Bay Area. The self-service car wash is available 24 hours. If you're speedy and can perform all phases of soak, soap brush and rinse the whole thing will cost a "whopping" $3 bucks. But don't forger the towels otherwise your car will have to air dry on the freeway. Seld service vacuums and air pump is also on site.
