RIDGE WASHER 16-Inch Undercarriage Cleaner with Foam Cannon — 4000 PSI

Elevate Your Undercarriage Cleaning

The RIDGE WASHER 16-Inch Undercarriage Cleaner is designed to tackle tough grime without turning undercarriage maintenance into a crawl-under ordeal. Built for drivers who want a thorough, surface-safe clean, this setup helps remove road grime, oil residues, and stubborn dirt from the underbody, suspension, and chassis with controlled, high-pressure spray.

With a modular design and flexible connection options, you can tailor your workflow to the vehicle and task at hand. The kit supports multiple configurations so you can pair your pressure washer with the right accessory combination for faster, more efficient cleaning around trucks, SUVs, trailers, and commercial vehicles.

Versatile, Ready-to-Use Connection Options

Three practical connection methods cover a range of jobs and setups:

• Pressure washer gun to wand to undercarriage attachment (stainless steel small aperture nozzle) for compact setups.
• Pressure washer gun to foam cannon to wand to underbody washer (brass large aperture nozzle) for abundant foam and thorough rinsing.
• Foam lance to the black soap nozzle tip for focused foam application where it counts.

Performance and Range

The undercarriage cleaner supports a broad pressure range from 1500 to 4000 PSI, performing best when your machine operates around 2500 PSI or higher. This flexibility helps you adapt to different surfaces while maintaining control and reducing splash.

What’s in the Box

Real-World Use and Benefits

Whether you’re maintaining a family SUV, outfitting a fleet trailer, or keeping a commercial vehicle clean, this cleaner offers a practical, hands-on solution. It helps you reach the belly, frame rails, and critical corners more easily, saving time and reducing the need to crawl underneath.

Note: For optimal results when using both the undercarriage cleaner and foam cannon, choose the brass large-aperture nozzle. The small-diameter stainless nozzle can cause leakage at the junction where components connect, so matching components is recommended for a seamless setup.
