I recently did a white car that had never been detailed. It felt like grit city!
I did the two bucket wash, Iron-X then the Speedy Prep Towel (FINE).
After reading here...I took out a new clay bar and decided to check it out.
I could find no contaminants on the clay bar on any of the sections tested.
That is good to hear. I have had people tell me both ways. I am thinking it really depends on the type of contamination and how many time you go over the surface.
