I too think Dawn's effectiveness is over-rated. Compared to a product like AutoInt's "A", it's not really very strong. I had it NOT
remove wax plenty of times (back when I was using it). It didn't do much to a month old coat of
Meg's #16, that's for sure. It's not really INeffective, it's still stronger than just mixing up a stiff wash solution. It DOES clean "looks only" waxes like
Souveran off pretty well, and glazes/fillers too.
Kinda interesting, we (myself included) say "Don't use Dawn, too harsh for rubber, dries out paint, etc." but it's just NOT all that strong compared to some products that are MADE for cleaning cars.
