A tough day, 14 man hours with no break. Fortunately I had a mate with me  
Here's a 'before and after' image I took in the worst room:

HD-X pre-spray, then HWE with prochem double clean. Amazing stuff.

Why use a high alkaline pre spray followed by high alkaline rinse?

[Paul Moss]

To get that result with a porty

[Jamie Pearson]

So he didn't have to scrub salty water into it for an hour before rinsing.

[neil 47]

I may be wrong: the pH end result is not effected by the pre-spray/spot treatment used with a HWE system.  It's rinsed it out anyway.  It's the pH of the rinse solution that determines the pH end result.

Assuming your system/method is efficient enough to completely rinse the pre-spray.

[davep]

Your rinsing with double clean that is ph 10

[david@zap-clean]

Your rinsing with double clean that is ph 10

  Yes. It's a rinse product for HWE.

prochem double clean. Amazing stuff.

It's a bit of a myth that a rinse agent will have a profound effect upon the result, if the soil isn't loose and held in suspension by the time the wand reaches it, then a rinse agent that is only on the carpet for a split second ain't going to help. More likely your pre-spray, pre-treatments did the trick.
