Rollover - low ph then alkaline or other way around?

[JustClean]

Hi all
I am pretty new in the business and I try to tweak my Washtec machine to get the best possible result. I changed chemicals to CSI. Self serve bays great - automatic okay but I think it could be better.
I use the SS bubble foam as a pre-soak and then I use "low ph sensation" as shampoo during the wash cycle. CSI confirmed that's okay. By doing this I wonder if I have enough lubrication to prevent any scratches (low ph = enough lubrication?). It could be my imagination but I didn't see some small scratches last week on my car ;o)
Once I saw an explanation on acid/alkaline or alkaline/acid here on this board but I can't find it anymore. Any ideas please?
Thanks. Cheers.

There are low pH products that will provide plenty of lubrication. I think it has more to do with other properties of the product than it does pH level.

We use an alkaline product first, then a low pH shampoo to get a drier car. It works well for us.
