What the best method to safely clean your engine bay? Did some off roading and my engine bay on my Gen 3 is pretty dusty is it safe to shoot some mild cleaner on it and hose it down? Any components that need to be covered from water intrusion?

I use a sprayer on the end of a garden hose, use the shower setting. I've used simple green, my normal Meguiar's wash and wax solution. The only time I had a problem was when I used a leaf blower to dry, it blew water into the electrical connectors. You should be fine spraying water on the engine as long as you don't go crazy in one spot, keep the spray moving.

Soap on towel, spray soap on engine, hit the big stuff with the towel, rinse. Towel / compressed air. Now the important part.....soak in WD-40 (water displacement - formula 40), wipe off what you can get to and the drips. Done every car & truck I have ever had owned this way, not greasy, keeps plastic & rubber from drying out and fights rust. I've had people look under the hood of vehicles I've had with over 200k on the OD and they think they are looking under the hood of a new vehicle. The key is also don't let it get to bad under the hood and do this every couple of washes to keep the new look.
