Emulsifier will clean better and look better than the fiber (acid)thethe rinse. So we prefer it over neutralizing the carpet. We've did the acid rinse for years wanting to leave the carpet as neutral as possible. Neutral did look as good so we went back to clean with the minimal risk of residue.
Exact same experience here.
Rinsing with emulsifier cleans better, looks great, less stains come back.
And "neutralize" is hogwash, unless one is using an inferior emulsifier, or pre-spraying something really crazy that they shouldn't to begin with.
I did side by side tests quite a few times, including twice in my home- No difference in looks and or re-soiling whatsoever.
Willy, we know that the residue argument, in properly mixed emulsifier is bunk. I use pre-spray as needed. If it saves me time when heavy soiling is there, I'll use it, as it will take me less time than the additional passes.
For normal light soiling it is not necessary.
As well as no need for crazy pre-scrubbing or rotary machines.
Coming to think of it, neither is a blower 8000 and up.
