What to use to clean a really dirty drivetrain?

My plan is to remove the derailleurs and soak them, then use compressed air to blow out all the gunk. I'll give the bike a good cleaning and replace the chain.

Is soaking in a degreaser a good idea? Any potential damage to parts or finish with an overnight soak?

My choices at home are citrus degreaser, TSP, isopropyl alcohol or methyl hydrate. I also have xylene but hesitate to pull that nasty stuff out. What should I use?
