Hi
Query from a newbie, I`ve been using my new CFR pro 500 for six weeks and would like to keep to the CFR range of chemicals. My query is, if I have an 80/20 wool carpet to clean which is very soiled and I use onestep premier pre-spray(ph9.5) should I neutralise it with my A-excel acidic rinse(ph5.3-5.6) in the tank. What I have been using to be safe is Onestep premier fine line (ph6.
and rinsing with water which I don't always think gives me the best result on a heavily soiled wool carpet.
Many Thanks
