Philadelphia Man Questions Whether Car Wash "Undercarriage Cleaning" Service Is Genuine

A Philadelphia man questioned on TikTok whether a local car wash actually provides the "undercarriage wash" service it advertises. He noted that although the service carries an extra charge, he suspects the vehicle's underside isn't actually being rinsed. To test his theory, he called on owners of vehicles equipped with underbody cameras—such as the 2025 Ford Bronco—to help record the car wash process. Some commenters shared his skepticism, while others acknowledged that car wash machines do spray high-pressure water, albeit with limited effectiveness. Experts recommend washing the undercarriage at least once every quarter if you frequently drive on salted or muddy roads to prevent rust. Consumers can either clean it themselves using a low-pressure hose or verify whether the car wash facility has ground-mounted nozzles that spray upward to ensure the service is genuinely performed.
