~One man’s opinion / observations ~
A car wash concentrate that has a lot of suds is not an indication of how well it works (but it has a good marketing effect) water sometimes contains high levels of calcium, iron, magnesium and other minerals that interfere with the cleaning ability of soaps (and as a secondary effect it’s ability to produce suds) as the cleaning agents react to the minerals trying to clean them, thereby diluting the soaps cleaning ability. Chemists add another agent (chelating) to bind the minerals thus allowing the soap to concentrate on the soil.
~Hope this helps~
