I have spent endless hours reviewing chemicals, their attributes, how they clean or shine. I am assuming that you are talking about Blendco or the new system Stone has out for their PreSoaks. As a newbie you need to become somewhat of a chemist to understand how cleaning occurs. I am not sure if you have a friction wash (ie., brushes) or a touchless wash. The pre-soak in a touchless wash is critical in the cleaning process. I have uses all kinds of different pre-soaks over the past few years and have come back to a powder form that uses a super saturated concentrate. It is a slick system but an expensive way to clean cars. The only thing that is more expensive is losing customers because your pre-soak does not work in a touchless environment. I suggest you take the time and interview many chemical suppliers about how and why their presoaks work. Some will offer a Hi PH (alkaline) presoak only. Other will offer a high presoak pass followed by a low PH (acidic) pass. Cleaning a car with chemicalsand high pressuure water is somewhat of an art and changes through out the year based on temperature, road conditions, pollen, bugs, clay, etc.. Become a student of the pre-soaks (and all your chemicals) so you can understand how to get best results. It will make you feel better when you get compliments from your customers and when you are paying the expensive chemical supplier bills.
