Pittsburgh Pride Car Wash is located off of Greenfield Avenue near the Swinburne Bridge.
It has 4 self-service bays with vacuums and 1 automatic wash. The automatic wash has nearly the same pressure as the self-service bays. The tools and hardware are a bit dated but they get the job done. The soaps and detergents are always stocked well and get your car shiny and clean.
** I would AVOID using the change machines and ALL other coin operated "pull" vending machines. They are very out of date, not stocked, and dented from people punching them in protest as they take their quarters without dispensing the product. I tried on a few different occasions but left empty handed. **
