It's not rocket science...don't overthink this!

1. Hose it off to remove the big dirt.
2. Scrub dirty areas with whatever cleaner and brush you like or have.
3. Hose it off.
4. Smoke cigarettes.

The people who wear tin foil hats will tell you to cover plastics with foil or plastic or not use this or that cleaner or cover your air filter or XXXXXXXXX crazy advice. I follow steps 1 through 4 and have had zero issues. I've done it hot and cold and only avoid the air filter (I have an intake) if I know I will be driving soon, otherwise I hit it with 900 PSI of water and the scrub brush.

I like to use engine degreaser. Whatever is cheapest from the parts store. Take the car to a do-it-yourself carwash. Cover the engine in like 3 cans, try to get it everwhere, underneath and what not... Then rinse with the high pressure wash. Don't hold the nozzle too close to anything (like no closer than 10"), and the pressure won't hurt.

Before doing a big project, clutch or whatever, I like to take a jack with me to the car wash, and lift the car some, so that I can spray the underside better. It's much more enjoyable to work on a clean car. NEVER GET UNDER A CAR NOT SUPPORTED WITH ONLY A JACK!

simple green the heck out of the engine bay, let sit for a few, pressure wash at low psi or even use regular garden hose on 'fan spray' setting. wipe down with microfibers and apply plastic dressing (water based) of your choice if that's your style.

Did mine for the first time ever with 100k miles. I got P21S and the EZ detail brush from detailers domain it was super easy and worked great! The P21S works great and is safe for your paint. The ez brush gets into all the nooks. A lot of people use scrubbing bubbles bathroom cleaner. Just keep your airfilter dry, if you have a k&n or something similar.

1. If you have an intake, put a plastic bag over it, and duct tape it.
2. Spray some degreaser all over the engine bay. (try to avoid the alternator)
3. If you really have to, brush the dirty areas (I've never needed to.)
4. Pressure wash it. (I do 1200psi)
5. Let it dry, or dry it off with a towel.
6. If you want, put a protectant on trims pieces/pipes, etc like Aerospace 303

Diluted simple green, brush and scrub. A hose with light pressure. Rinse, simple green again and rinse. Simple as that.
