Washing engine bay

I have a 2008 6.4 and I need to clean and degrease the engine bay, can I use degreaser and pressure wash it or are there things I can't get wet in the engine bay. I know on my old 02 7.3 there where some things you could get wet and that's why I'm asking any advice/help is very much appreciated. Thank you

Just be careful around sensors and rubber hoses. I'd just get some good engine degreaser and spray it on and let it soak for a while. Then just use a water hose to rinse I down

Might also look around your area for someone that will steam clean it. Usually can be done for $50-$150. Nothing will get it cleaner than a thorough steam clean.
