Open your minds and knowledge will follow.
Yes, Dawn belongs in the kitchen and if one has the time, knowledge of other dedictaed prep de-waxers, or intends to polish prior to applying a LSP that performs best when applied to a surface denuded of oils, please use that product. Period.
This elite attitude about the once in a while use of a APC, in reality thats what Dawn really is in the broadest sense, is unfounded and not based on the true science of detergents, soaps, pH, surfactant chemistry, paint and trim vulnability etc.
Let's face it, more people use dish washing detergents on their vehicles than those that don't and many of us, including myself, has done so in a chronic manner in the past (distant). Indirectly, leading to a wax or QD shortly thereafter because the shine was dulled.
Zaino was not created just for elite detailers, but for the general public.
