I have to wonder at your trialling of products & at your efforts to clean carpets ?
If you suggest something is rubbish, when it's been proven to be, quite the opposite by many experienced and professional users, you leave yourself open to question.
I was introduced to m/s about 8 years ago, when they were introduced to us by Franklins of Sheffield, the oldest c/c in the UK..........WELL OVER 100 YEARS..........and along with the full concept, which was......
prevac' / spray a mist of m/s over an area of around 10 sq metres / agitate with the excellent Klanz / rinse/extract with one of the CFR machines.
Franklin's were the distributors for all of these products and they complimented each other very well. What attracted me, initially, was the thought of only having to use a single product, for all carpet and upholstery cleaning, which turned out to be a bit ambitious.
Over 22 years in this business I've tried and tested hundreds of products and found a few to be outstanding, others to be good and some to be, less good.
Even the cheapest would get a result - with effort - and the ones I particularly disliked, were the ones which created too much foam and required defoamer to be added to the return tank.
Each of us has to decide whether we, like a product , but we have to be reasonable and accurate when judging.
have a nice life

Ps............there is no magic formula, but the individual approach to cleaning will have a bearing, sometimes, dramatic, on the outcome
