Is foaming a car a necessity?

Bunky · Apr 6, 2010

Hard water, which is any water that contains high concentrations of calcium, iron, magnesium and other minerals, thwarts the cleaning ability of a chemical. This is because the cleaner reacts to the minerals in hard water as soil, which uses up the cleaning agents. To counteract this, foams used for foam canons contain chelating agents to bind the minerals, allowing cleaning agents to remove the soil unhindered. This is why some foam concentrates seem to foam better than others. The amount of foam produced has very little to do with how much concentrate you use.

This addition of chelating agents also applies to car wash soaps and detergents like MicroRestore.

I thought foaming was also about adding lubricity (a way to spread a lot of soap and stick to the paint in some economical manner) in addition to the cleaning by the soap itself.
