Mike,
I too have wondered about how much some cleaners agitated prior to using micro-splitters.
For myself, having 'grown up' in carpet cleaning from the days when extraction power was very much less than is available today, I have always conducted each stage of the cleaning process to its' full extent.
Consequently I am sure that my comparison between MS and conventional is realistic.
However, I do still carry 'conventional products on the van. At the moment I am in the process of racking out and swapping to a new van. From the racks on one side I removed no less than 64 chemicals and have not touched the long shelves on the other side.
I doubt that I shall ever relinquish most of these old problem solvers, but would, as a generality, contest your statement regarding Traffic Lane Gold, excellent though it is.
Regards,
John.
