Degreasing Engine???

Haven't cleaned the Scamp's engine yet. On my newer car I use Simple Green. I don't use the Purple degreaser because it can hurt aluminum.

For rinsing I use the garden hose without any attachments so that the water flows downs the engine. Pressure from a nozzle can push water into sealed places like electrical connectors and whatnot. They should handle the pressure but just want to be careful to avoid electrical issues.
