How do you get that crystallized urea out of there? It doesn't hose out with water does it? I'm thinking it is more like a calcium deposit, and will need some sort of chemical to remove, or am I off base on this? I tried google to find my answer and came up empty handed.

On a side note... I think politicians should all be forced to drive vehicles with these EPA systems in their POV's. To throw this technology that is no where near prime time at one of our nations most vital industries is criminal in my book.
