Why Foam?

Foam cannons are more than just a fancy upgrade—they’re one of the best tools for a swirl-free wash. When used correctly, foam clings to the surface, emulsifies dirt and debris and can be rinsed away without scrubbing. But hard water can affect the quality of the foam and leave mineral deposits and residue on the surface. To mitigate this use a water softener or specialized cleaning solutions for hard water.

This reduces:

• Paint scratches and micro-marring

• Detailing time and effort

• Amount of soap and water required

• Wear and tear on wash mitts and towels

Whether you’re preserving a brand new ceramic coating or just keeping your daily driver looking great, a foam cannon is part of any proper car care regimen.

Thick Foam for Every Wash

What sets this foam cannon apart is its ability to produce thick, creamy foam that clings to the surface like shaving cream. That’s thanks to the brass nozzle system and wide-bore internal orifice that combines water, air and soap at the optimal ratio for lather.

The 1-liter container is perfect for small and large vehicles, enough to foam an entire car, truck or SUV without having to stop and refill.
