-Cover engine with water-based degreaser/APC (I like Ardex Green Stuff Plus)
-Let sit 5 minutes, but do not let dry
-Rinse with a hose with a nozzle, generously.
-Dry with compressed air via blow gun
-Apply dressing of choice.

Here are the results of that process on my 112k mile 330ci.
I wish my engine stayed that clean, but unfortunately none of ours do, do you recommend covering anything?
