do 5 to 6 scoops. I think 8scoops is way too much, especially with the water pressure at only 350. That seems like you're leaving too much pre spray behind which is browning after it dried.

Thank you - now were talking, less is more and he's saving me money........I'll try that on the other house which will be coming up. \m/

How old is the carpet does the yellowing disappear after you treat it and reappear?

I would normally go back and light rinse with all fiber rinse.

If that doesn't works it could be a old stain master and it needs to be treated with citric acid.

it's 10 years old (nylon) and it's been cleaned they said about 5 times, they also said that no one has cleaned like me - best it's looked in years, that is after I spray away the wicking. After I touch it up it looks really good. The customer and I agree on that and it's a nice quality carpet. (ty)

I know it's tough not being there, seeing only a few pics, but I really do appreciate all the reply's, suggestion's, & snarky comments (Mikey P. I was cracking up. :)
So I'm going to,
1) Bump the pressure to 450 instead of 350
2) Use less Flex, 5 scoops instead of 8
3) Put a air mover in each room as I finish it

You really ought to consider bonnet cleaning. Marty is right. Post-bonnet clean it using Encap-HydrOx. I guarantee that Encap-HydrOx will cut through the browning!

The reason for recommending Encap-HydrOx is that it contains a STRONG mix of hydrogen peroxide in an extremely acidic base. Plus it encapsulates very well so wicking is impeded. The combination tears into browning! It's an easy solution.

I would guess the carpet has way to much "cleaning agent in it" The customer probably tried to clean it with Foam in a can or Resolve or some other product or you had a malfunction and applied to much product or didn't extract enough. Next time Just put some water on a small spot of Discoloration and agitate I bet you get copious foam coming up. "it's not browning", browning as I know it, is from cellulosic fibers not synthetic.

I learned that too. Bob Wittkamp taught me that many years ago in my first IICRC class. And years ago that common idea made sense. There was cellulosic jute backing in most carpets, hence cellulosic browning was a common occurrence. The assumption back then was basically that all carpet browning was caused by cellulosic backing. However, modern carpet has synthetic backing, yet browning still occurs. How is that possible? Quite simply, browning is coming from other sources. But from where? Here's a sceneries that seems to make sense... A high degree of soil comes from outdoor dirt. And dirt from outdoors is largely comprised of decomposed plant matter. And plant matter is cellulosic. Following that line of reasoning, cellulosic browning could be caused from embedded tracked in soil in the backing of the carpet. Deeply embedded soil is very common with CGD carpet. CGD carpet pile can become crushed, and can trap a lot of soil at the backing of the carpet. The soil can load up in the back and wicking can occur when the carpet gets cleaned. Hence the problem of browning on a modern commercial carpet is still a very relevant condition.

I believe there might be cellulosic material in the latex glues as filler material.

Interesting theories and who knows, they may be right.

However, looking at the dirty water that comes out of the recovery tank, it is pretty brownish/blackish to begin with, even without "browning".

How about considering plain old wicking, due to soil overload, that was dissolved yet not completely flushed. It is hard to flush, as once dissolved it may have been pushed into the glue layer and later wick, and the latex will not release it till dry. Over spraying traffic lane cleaner followed by too high psi and not picking water quickly with the dry passes, will do it every day.

A real good acid flush with good technique, followed with plain bonnet pass may be good enough.
