So I've been looking through the photos of some of your cars and I'm curious how some of you guys who drive your sixes daily (or at least regularly) manage to keep the engine bay so spotless. Mine is a bit of a mess. The head is tarnished and has oil discolorations, the painted surfaces are dull, and everything has a general coating of road dust crap on it. I tried that spray on engine block cleaner once, never again. All that succeeded in doing was getting water in my spark plug holes when I rinsed it off. So, any suggestions? First to get it clean, and second, to keep it that way? Thanks.
