Our underbody wash system is mounted to the conveyor frame. As the vehicle moves across the applicator, dirt and debris is removed from its underside. First, the applicator, which is equipped with 1 of 4 spray nozzles, soaks the underbody before then applying an anti-rust formula. Regular cleaning of the underbody helps prevent rust and corrosion, improve fuel efficiency, enhance appearance and safety, and maintain car value. The housing of the applicator is made of stainless steel. All the plumbing fittings and fixtures come pre-assembled. This makes for an easy, plug-and-play installation process.
