I've tried, I soaked the mother in degreaser but I lack the patience to sit and scrub every spot. So I just blast it with water and the nice big areas, like the fender linings go back to a luscious white, but the cramped nooks and crannies just get worse and there is no way I can spend the time redoing all the wiring and hoses and such (no where to neatly rout them). For the most part I just tell myself people don't know what they're looking at under there and I don't pop my hood much so it's wasted energy to make it all pretty when I know what everything does and where it is. Thanks for the tip though. I'll put the effort into doing half of the work if any OCD IA member ever wants to come over with an arsenal of brushes and chemicals to help me tackle it.
