How do you clean your engine bay?

[Entropy]

I finally decided to give my engine bay a "deep clean." I covered the alternator as best I could with a plastic bag, sprayed everything in Simple Green (let it sit for a couple minutes), and then lightly sprayed it down with a hose until all of the Simple Green was gone. I was amazed at how clean it was after just one clean job.



At first I was hesitant to use the hose, but many people seem to do it without issue (after all the engine gets soaking wet during heavy rain anyways). How do you clean yours?
