  I wonder at what point soot on the functional parts becomes an issue, and how would they get the really caked-in stuff off? lasers?

    The clean them pretty well. For example the clean along the welds to check them. The soot only stays on the parts where it doesn't really matter. Engines are also cleaned. In fact, one landing failure happened because left over cleaning alcohol in the engine itself.
