Hosing down the engine bay

[Black97civic]

I dunno about removing anything, we degreased dozens of engines at the dealership I worked at, and we even left the cars running half the time. I guess the key is not to aim a pressure washer and sensitive stuff, but just use a low pressure stream, and let the chemicals do their work.

I personally have had luck with the simple green and garden hose route, but my stuff wasn't all that nasty to the point where it would require scrubbing.
