My explorer hasn't been waxed in over a year bu I was my F-150 pretty frequently, and I've just added a step after waxing that not only gets the white crap off the trim, but makes the trim shine black as well, its by mothers, called "back to black", I used to use wd-40 but that just got off the white stuff, didn't really clean the trim too much, this stuff makes the trim look great as well as getting off the white stuff.
