In reallity ive just started out in my carpet cleaning trade using pre spays and then an acid rince to finish then doing a final ph test on cleaned carpets im finding that its generally about ph6 is this about right, also im using a cfr 400 and what i cant get my head round is the fillter side of things ie using a final rince to remove  pre spay but i cant see the filters removing the first chem that ive put down just  mixing the two together
can that be good for the carpet?.
though i have found it does give good results from my limited experiance

The topic MICRO SPLITTERS probably answers your question about Ph levels.

In theory you should try and get carpet back to ph neutral, with wool slightly to the acid side. But as you will have seen from the other topic it is not as crucial as manuals etc might make you believe.
Best advice if you're unsure - follow book methods until you have enough confidence to experiment and know how to rectify if things seem to be going wrong. So you won't go wrong if you clean alkaline rinse acid.
(some specialist materials might be different btw)

I agree with Neil but if you are applying a protective treatment (stainguard or scotchgard) then you need to leave the carpet after cleaning at 6ph so that the treatment will bond.
