I tried degreaser when the engine is hot once...

Well... its an old honda civic "93" my buddy used to own... well I sprayed that "solder seal" engine degreaser when he came to my place and ask me to wash it bcoz his going for a group meet, so I hustled and sprayed it with E.D. and about 3 seconds after I sprayed it, nasty smelling smoke came out... then I hit the freakin header! and it went to flames! quickly he grabbed his "NOS lookin" fire extinguisher and sprayed the hell out of it!

the engine lining he installed got melted a bit and he told me to just stop it... and he just went to the club meet with a nasty lookin engine with a burnt hood padding...

what I'm saying is some cars need the engine cold just to clean it safely...

Why degrease an engine that isn't greasy? As a note, those degreasers are powerful, so be careful not to get them into parts with bearings (ie. the alternator pully, A/C compressor pully)...
I just use low pressure water every time I wash the car and my cars stay nice and clean under the hood. Yes, I'm careful where I spray.
I would only clean under the hood by this method if I were tring to sell the car. Your pictures look great!

Good question, and a simple answer really - obviously to break down any new grime that's on the engine, but also to remove the previous application of dressing/protectant, so you're working with an absolutely clean surface.

It's a little of a catch 22, but it works great

The engine is not ment to be "HOT", it's ment to be "warm to the touch".
