I have seen many pics of some super clean engine bays. I want to do a better job of cleaning my engine bay. I have never used a hose and spayed the engine bay down. I always get a wet sponge and do my best to get all the dirt out but it ends up drying with dirt smears. Is it safe to spray the engine bay down with a hose? Any areas I should avoid spraying down? How do you fellas clean your engine bay? I've always been nervous of getting a wire or something wet that should be. Let me know. Thanks fellas.
