Hi Daryl
In general terms, I haven't used much detergent for many years, so can't comment on One Clean/Formula 90. All I will say is I am obtaining superb results. Even slightly better than my previous micro-splitting solutions.
As for cold water rinsing, it works for me and for the way I work, I honestly feel that it rinses better than hot water. Please note, I am talking about rinsing, NOT cleaning. I am sure many will disagree with me and the debate is well worn, so no point in taking it further.

Yes you are correct about electriacal agitation machines being another machine demanding power. BUT by using my 550 watt Envirodri machine to agitate the carpets and pre-spray really well, I considerably REDUCE the time spent rinsing with my +/- 5,000 watt extractor. Therefore, good use of a machine to agitate should be a more eco friendly practice than light agitation with a pile brush and extended extractor use. Oh, and the carpet drys quicker and looks better for it too
Safe and happy cleaning
Ken
