How To: Wash Your Engine Bay
Since many people have been asking a how to on cleaning your engine bay, here is a write up on my procedure. Hope this answers everyone's questions.

1.) Park Jeep- :lol:

2.) Let Jeep sit for 45 mins to cool down.

3.) Cover up PCM with plastic bag, old pillow sheet, whatever. But once you do this often, you dont have to cover it anymore because you'll be experienced by then.

4.) Do initial rinse pre-degreasing. You can use a garden hose or a powerwasher (low pressure setting) for each rinsing step.

5.) Spray on a diluted de-greaser. It could be Simple Green. (What I liked was the Chemical Guys "Grime Reaper". Works awesome.

6.) Agitate the degreaser on the needed areas.

7.) Let it sit a while.

8.) Rinse.

9.) Repeat steps 5-8 if you missed a spot.

10.) Dry as much water as you can with a towel.

11.) Spray on a dressing. I LOVE Chemical Guys "Bare Bones". OMFG it works awesome.

12.) Spread the Dressing with a microfiber.

13.) Viola, you have a clean engine bay.

This should be your end result:

Re: How To: Wash Your Engine Bay
what about the battery and intake?

Re: How To: Wash Your Engine Bay
Battery, do not worry about.

Intake, if you have a CAI that sits at the top of the bay, cover the filter with a plastic bag. If you have a Bwoody- Like I did for my old Jeep, do not worry about it.

BTW- If you have a lot of painted parts under the hood, use car wash soap and a spare mitt to scrub the painted parts. I wouldn't take the chance with the de-greaser.

The Chemical Guys de-greaser I used did not do any discoloring.

If you do use a de-greaser, PLEASE DILUTE IT.
