I was filling up my windshield washer resevoir today and noticed how much dirt and grime had accumulated in the engine bay and I figured cleaning it would be a good job for tomorrow afternoon...

What is the best way to clean the surfaces of the engine bay? I've heard of steam-cleaning, but obviously I don't have that capability in my garage. I was thinking of using those Armor-All Wipes because I've used them in the past and I figured they were safer to use then spraying some form of cleaner all over everything.

Can anyone chime in on this and recommend a method?
