Why it works
Four things that matter.
Thick, even fan
Lays down a dense sheet of foam across the whole panel in one pass.
No jet wash needed
Foam with no pressure washer and no hose attachment. Simple.
Premium build
Smooth pump action with metal components and nozzle, built for durability and consistency.
Built-in measuring jug
Dilute accurately every time — markings inside and out, 50ml of product to 2 litres of water.
The method
How to use it
1
Measure
50ml of product using the markings on the built-in jug.
2
Fill
Top up with water to 2 litres — enough for one vehicle.
3
Pump and spray
Pressurise, then lay down a thick even fan of foam. No hose or jet wash needed.
The detail
Built to perform.
The missing piece of the wash routine. The K+W Foam Spray Cannon delivers thick, clinging snow foam across the entire vehicle using pressure alone. No jet wash. No hose attachment. No compromise. Built to work with our Ceramic Snow Foam and Pre-Wash Snow Foam straight out of the bottle.
