So, what is the collective preferred method for cleaning
engines/compartments?

I've used the Gunk brand spray on degreaser with some measure of success. I
am reluctant on aged engines because I am concerned about water getting in
through old, dry seals and such.

Typically, I have sprayed on the Gunk stuff on a warm, engine, allow to
dwell, rinse off with hose with the engine running. This is not so welcome
envrionentally speaking. So what to do?
