Anyone with even an elementary knowledge of the chemistry of cleaning will know that the nearest 'product' to the cure-all is......................... Water.
Different problems require different solutions. That is a fact.
To attempt to combine all the requirements into a single product can only result in conflicts - it cannot at the same time be acidic, alkaline, neutral, ionic, non-ionic, cationic etc.
Micro-splitters do tackle a wide range of soils very well, but the day of a single-chemical van has not, and probably never will, come.
PS. Before someone else points it out, a solution with a pH lower than 7 can be an alkali.
