It's not all that difficult, but I'd refrain from using the pressure washer. Hot water from a hose is helpful, but high pressure isn't the best idea. Use whatever combination of blankets and plastic you need to keep the interior dry. I've used S100, Super Clean, and the foamy Gunk engine cleaner all with good success. Stay away from the alternator, and when I'm done, I grab my blow gun and blow off as much as possible before starting the engine.
