So is it your belief that a "car soap" could bring water to a PH of 7 as you state in your post? If so, how is this accomplished with in the chemicals that make up the soap.

Well, this question got me thinking, and I suspected that the small amount of soap used would not be enough to change the PH, so I tried an experiment. Although I didn't have any Dawn, I had three different car washes and two different dish soaps.
The Products:
My Tap Water - PH = 7.2
Poorboys SSS - Says is PH neutral on bottle - mixed per directions PH = 7.0
Optimum Car Wash - Doesn't mention PH - mixed per directions PH = 6.7
Finish Kare Wash/Wax - Doesn't mention PH - mixed per directions PH = 7.0
Palmolive Dish Soap - Doesn't mention PH - no directions 1oz/gal PH = 6.6
Cascade Dishwasher Soap-Doesn't mention PH-no directions 1oz/gal PH = 8.0
So it appears that the soap does change the PH of the water but it's hard to tell by how much since my water is close to neutral to start with. I wish I had some Dawn to try just to see if it is as caustic as the Cascade is. Besides the PH thing, another disadvantage to dish soap is it's grease and oil cutting ability which will tend to dry out rubber door seals and trim.
This experiment proves two things:
1 - I have too much time on my hands!
2 - My wife now thinks I'm craizer then she thought before!
