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
