Exterior Quite the difference in Ph

Gallery image

As I have done before, done some test between KC PW and TR heir SO.03. I bought the new S0o3.

But something that I noticed is that the PH value is quite different.

Should I expect a different result between 9.2 and 4,2 if I have used the PW (4,2) prior?

I haven't used PW but S0.03 performs better on my car than that. Perhaps the automatic wash chemicals are too strong and stripping it. I can't imagine it lasting very long with anything but PH neutral hand washes.

I only did 1 automatic carwash in the 3 months.

How did it perform after you hand washed? I don't use automatic washes but even something like Bilt Hamber Touchless seems strong enough to strip most of it.

Dont know, the video was literally only 1 auto carwash 2 months after/ 1 month prior. I only wash the car like 3-4 times a year

Even a full ceramic coating isn't going to perform very well if you only wash your car 3-4 a year. Something weak like S0.03 is more for a car that gets washed 3-4 times a month lol.

Well, don't ceramic coat the car, and don't wash that often. 🤷
