"No jet wash on the drive and I'd been putting off a proper wash for months. This changed everything. Ceramic Snow Foam through this and the foam is thick and clingy. Car hasn't been this clean since I bought it."

Why Ceramic in a Snow Foam?
A pre-wash removes dirt. Our Ceramic Snow Foam does that and then leaves something behind. SiO₂ ceramic particles are suspended throughout the formula, so as the foam dwells on the paintwork and lifts the contamination layer, it simultaneously deposits a thin ceramic barrier across the surface beneath.
The result is a product which cleans and protects in a single application. The high-foaming formula clings to vertical panels, extending contact time so the chemistry works thoroughly on paint, glass, plastic trim, and coatings without the pH aggression that would compromise a protected finish.
Safe on all waxes, sealants, and existing ceramic coatings. Start every wash with protection already in place. Built here. Tested here. Proven here.

Step 1 - Fill to your required level
Fill the 2L barrel with water first, then add your chosen K+W formula following the dilution guide on the bottle. The measurement markings on the built-in cap make this precise every time. Attach the snow foam nozzle for thick foam, or the rinse nozzle for more targeted application.
Step 2 - Pressurise
Screw the pump top on firmly. Pump 20–25 times to build pressure in the barrel. You will feel resistance increase as pressure builds - this is normal and indicates the cannon is ready.
Step 3 - Apply to the vehicle
Begin at the roof and work down. Hold the cannon 30–40cm from the surface and apply in slow, overlapping passes. For snow foam, allow to dwell for 2–3 minutes. Do not allow to dry on the surface.
Step 4 - Rinse
Rinse thoroughly with a hose or a second cannon filled with clean water. Follow with your normal wash routine.

"Bought this with the Snow Foam System bundle and it completes the kit. Pressure is surprisingly strong, the foam coverage is excellent. Does exactly what a cannon three times the price does."
"Simple, well built, and the foam nozzle produces a genuinely thick layer. I was sceptical about a pressure cannon without a jet wash but this works. Measurement markings are a nice touch for getting dilutions right."
