Best All Round Pre-Spray
Best All round extraction Powder

dont think many will answer that ... cause its covered a billion times and there are many different brands that will essentially give the same results and there are different situations where certain products mat be optimized for a specific task .
Pick two though ...I generally just order citrus prespray and ultimate master powder these days , covers all situations and any time a niche product would be better is few and far between for me .

A fantastic product I have been using for a while now is Up and Out by Research Products. It is a prespray and it doesn't need an acid rinse as it self neutralizes. You can even use it as an extraction cleaner if you want to, however 99% of the time i use it as a prespray with just a water rinse. I have never heard of any one else using it yet. I have used it at full strength on all types of carpets over a long period of time with absolutely no problems and I still go back for more.

Used to use blits by Hydramaster, now Alltecs citrus prespray and liquid ultimate master in T/M. Have thought about using or at least giving a try to World of Clean products but slightly put off by their suggested dwell time before extraction..Simon
