Why Use a Foam Cannon?
Foam cannons allow soap to cling, emulsify dirt, and rinse away safely—reducing the need for aggressive scrubbing. This helps:
-
Minimize paint scratches and swirl marks
-
Reduce wash time and effort
-
Lower soap and water consumption
-
Protect clear coats and ceramic coatings
Note: Hard water may reduce foam quality. For best results, use softened water or high-foaming detergents designed for hard-water conditions.
Ideal Applications
-
Car washing and detailing
-
Trucks, SUVs, and fleet vehicles
-
Motorcycles and ATVs
-
RVs and trailers
-
Boats and marine equipment
