I clean my engine and intake using Simple Green and an air hose when the engine is cold. I do not use water to rinse or soak. This works great but I must be careful around electrical connections since the air pressure can drive moisture into connectors. If you must use water on dirtier engines I would suggest putting it in a spray bottle rather than using a garden hose.
I'm sure Gary has a different approach and you can find many of his cleaning tips on this forum.
