Keep in mind a lot of the strong alkaline products have corrosion inhibitors, but it’s mostly to mitigate their own corrosiveness. Andreas from DetailingSchool has a video where he puts a bolt into a bunch of APC and pre-wash products and you can see the oxidation.
I’m kind of down on most foamed on washes out of a foam cannon. I just never get results meaningfully better than a good soap. BH is good stuff but all of their products are super strong and some of them I think get close to the line as far as safety. I’ll probably buy Touchless at some point once my ActiveFoam runs out.
