Since I'm on this revisiting this whole pre-foam high PH lookup.....
Let's start the question.

Have you guys noticed anything negative on exterior finishes when using a Acid or Alkaline Wash in your regimen.

I'm generally a 36 month leaser, and sometimes a 24 month flipper...
The only negative I have seen IME, is the painted parts that don't have clear coat, like a gloss black license plate frame, will show accelerated wear.

Be curious what others see when running non neutral washes.
