That sounds like nonsense.
As I stated previously, ph neutral car soaps do not have *significant* standalone cleaning power. That is why on a moderately soiled vehicle, if you just sprayed it down with soap (foam gun/foam cannon), let dwell and rinse off, the vehicle would still have bonded grime and contaminants. Why? Because ph neutral soap is not strong enough by itself. You must introduce the mechanical aspect of washing.
Cleaning comes from the agitation by your wash media (ie. wash mitt, sponge, body brush). The soap contains lubrication and the surfactants which emulsify and loosen the dirt which allows it to be temporary suspended so that it can be flushed away with water.
I believe the biggest misunderstanding of ceramic infused soaps is that because they are very low sudsing by nature, they don't "clean" as well as high sudsing soaps. That is completely false. They will clean just the same as standard soap (because cleaning comes from agitation).
