What cleaner for engine bay?

[ga94gt]

I am pulling my motor this weekend and and I am going to clean the bay and get ride of the 180k miles of grime and dirt and was wondering what a good safe cleaner would be.

I was thinking Simple Green or Oven cleaner any other suggestions that would be better?

Simple Green works well, but expect to scrub and you will need to rinse it. I REALLY want to try an electric steam cleaner on my truck on of these days.

Gunk or Engine Bright.
