The AMSOIL Foam Cannon turns your pressure washer into a proper pre-wash tool, laying down thick, clinging foam that lifts dirt and grime before your wash mitt ever touches the paint.
Every time you hand-wash a vehicle, you risk dragging contaminants across the surface. That's how swirl marks and fine scratches happen. A foam cannon changes the process by saturating the entire vehicle in a dense layer of suds that encapsulates dirt particles and loosens them from the paint, so they rinse away instead of grinding into your clear coat.
THICK, CLINGING FOAM THAT ACTUALLY WORKS
A cheap foam cannon sprays watery suds that slide off the panel before they do anything useful. The AMSOIL Foam Cannon uses a 1.25 mm orifice to generate dense, clingy foam that stays on the surface long enough to break down road grime, bug residue, and brake dust. Pair it with 2 oz. of AMSOIL High-Foam Car Shampoo in the 35 oz. reservoir and the foam blankets the vehicle from roof to rocker panels.
ADJUSTABLE 360-DEGREE SPRAY PATTERN
Wheel wells, roof racks, lower valances, grille openings. These are the areas that collect the most contamination and are the hardest to reach with a standard wash. The nozzle adjusts spray pattern, orientation, and soap dilution ratio independently, so you can dial in a wide fan for flat panels or a concentrated stream for tight spots without swapping tips or breaking your setup.
WIDE-MOUTH, WIDE-BASE DESIGN
Small bottle openings make filling a mess, and narrow reservoirs tip over on the garage floor the moment you set them down. The AMSOIL Foam Cannon has a wide-mouth opening for easy filling and a wide base that keeps the unit stable on concrete, asphalt, or uneven surfaces. It's a small design detail that eliminates a common frustration.
BUILT FOR STANDARD PRESSURE WASHERS
The cannon connects via a 1/4-inch quick connect fitting that works with most standard consumer and commercial pressure washers. It operates within a pressure range of 870 to 3,190 psi and flow rates from 1.3 to 5.3 gpm, covering everything from compact electric units to gas-powered washers. Maximum water temperature is 140°F.
DURABLE COMPONENTS FOR REPEATED USE
Foam cannons with plastic internals and thin fittings tend to fail after a few uses, leaking at the connection or clogging at the orifice. The AMSOIL Foam Cannon is built with premium components designed to hold up over time. After each wash, rinse the sprayer components and reservoir with clean water and flush any soap residue. Avoid soaps or chemicals containing particles, as they can damage the internal components.
SPECIFICATIONS AND COMPATIBILITY

How does the AMSOIL Foam Cannon help prevent scratches and swirl marks when washing my car?
The AMSOIL Foam Cannon produces thick, clinging layers of suds that lift dirt and grime off the vehicle's surface before any physical contact occurs. By allowing the foam to sit on the vehicle for a few minutes, contaminants are broken down and lifted to the surface, reducing the risk of wash-induced scratches and swirl marks throughout the wash process. This pre-soak action means less friction is needed when hand-washing, protecting your paint finish.

Its 35-oz. reservoir capacity and adjustable dilution ratio valve give users precise control over foam thickness and coverage.
How do I properly use and maintain the AMSOIL Foam Cannon after washing?
For optimum results, mix 2 oz. of AMSOIL High-Foam Car Shampoo with fresh or deionized water in the reservoir, spray the vehicle in sweeping motions until full foam coverage is achieved, allow the foam to sit for a few minutes without letting it dry, then rinse from top to bottom with the pressure washer. After each use, rinse the foam cannon thoroughly with clean water, remove the reservoir, and flush all soap residue from the sprayer components. Avoid using soaps, detergents, or chemicals containing particles, as they may damage the foam cannon's internal components.
Is the AMSOIL Foam Cannon safe to use with any type of car wash soap or detergent?
The AMSOIL Foam Cannon is designed for optimum results when paired with AMSOIL High-Foam Car Shampoo. AMSOIL specifically warns against using soaps, detergents, or chemicals that contain particles, as they may damage the foam cannon's sprayer components. For best performance and to protect the unit, stick with particle-free car wash soaps and always flush all residue from the cannon after each use.
