Best way to clean the engine bay
My whole entire engine bay is muddy as hell and I would like some advice on the most efficient way of cleaning it without damaging anything. Thanks

Anyone has any experience cleaning an engine bay on a 2012 JK yet?
I've been using my new toy the way it's supposed to be used, and now my entire engine bay is really dusty and little muddy. What areas should I worry about? I figure I need to cover the air intake and battery...

I've used both Simple Green and 409 spray with a power washer. I found the Simple Green to be better, but 409 does well. When dry I'll take a can of WD-40 and spray the whole engine and hoses (careful not to get on serpentine belt) and then wipe down with a cloth. Shines up real nice and it also dissipates any residual water.

I just cleaned mine at the hi-pressure bay car wash using the technique outlined by Ludski. I detailed the plastic pieces using the Gunk tire shine. It looked beautiful after! 
Edit: Added gratuitous engine bay picture to show how pretty my 2009 engine bay is since cleaning it.

Why does everyone think spraying down a engine with clean water will do harm to electrical components? they are designed to be used in the outdoors and are sprayed with dirty/salty/sandy water every day they are driven in the rain/snow or offroad. 
I can understand not holding a pressure washer directly at a single part or connector for too long but a quick burst of water shouldn't do any damage.
I have yet to ever have a problem with using a hoes or a pressure washer inside my engine bay on any car I have owned.
