If You Had to Start Over

If I'm understanding the theory behind the chemicals correctly, DS 2 is your all arounder, Hydrox is for organic stains (coffee/soda), and something like Punch is for when you're dealing with heavy, grease-like soiling?

Also I watched your "how-to" video on the Cimex Rick.  Awesome stuff, and I assume not much has changed?  I think it was from 2011, but the idea seemed to be:

Light to no apparent soiling: Feather Cimex trigger for one pass.
Moderate soiling: One full trigger Cimex wet pass, followed by one dry pass.
Heavy soiling: Pre-spray, full trigger wet pass, followed by two or three dry passes.

You nailed it Matthew! You sound like a pro already. 
In fact that is the cherry on top with this system - it really is THAT SIMPLE.
