Hosing down the engine bay

[94talonawd]

I was looking at some of the products at the auto parts store.
I was curious about their engine degreaser cans.

Since engine bay is so dirty and my turbo is off at the moment. I was thinking about degreasing the whole engine down, scrubbing if I can too. Then hose down the engine bay with water. I just want the bay to look like its new.

What all should I wrap up in plastic so it wont get damaged?

What Ive already thought up was removing the batter, covering the alternator, coil packs, fuse boxes.

Any other ones that I might have left out? Or is this process even safe?

I need some opinions. Thanks!
