I see your point but ask this..... Have you ever had to "detail" a vehicle that has not been washed in years and sat under a tree? Admittedly an extreme case but you can use car wash & clay until the cows come home and it does little to nothing. What works as a starting point? Dawn. In short I have used it as a car wash only when required to begin the paint cleaning process. It worked well for me with no negatives. It also works as a "stripper" to start all over when prepping a surface. It works when other methods/products fail and certainly should not be used on a regular basis, that's what true car soap is for. No argument here, just saying that no problems were ever encountered over the years when I had to use liquid dish soap as the first step.
