I keep my car detailed fairly well. I'm anal about it, but not totally out of my mind like some I've seen around here.................

I don't use a seven step wax process!!
In any case, my 06 has this kind of cruddy, almost crusty residue on the rubber (synthetic, methinks) where the doors seal to the A pillar.
I never remember it when I'm at the dealer, so, does anyone here know the best product to clean and protect that particular detail?
