Engine compartment cleaning?

Can anybody advise on cleaning the heavy mud/dirt residue from the engine and engine compartment. I'm sure many of you have the same issue from big mud puddles. I have sprayed it down before, but I do get the electrical one the dash and stereo getting a little wacky for a brief time afterward. A lot of electronics an fire wall and stuff.

I have an '02 x 4.0l

Anybody clean theirs well?
Pls share. Thx

I use simple green with a couple brushes and a garden hose. I use aluminum foil to cover the air intake and electrical parts. No pictures, but it works fine.

Wheel. Break/Test. Repair/Upgrade. Repeat

There was a thread on here about using Gunk engine cleaner. I watched the video on YouTube and they actually used a TJ as the demo vehicle. It covered everything about cleaning the Jeep engine.

I used to be a fan of doing this until one time I had a big problem. Ended up with a misfire that cost me a few hundred to fix and a lot if down time. Was not a jeep.

Engine bays are designed to get wet to an extent. If it were me, I would avoid high pressure or a lot of water flow but instead, mist it on. But that's just me.

Someone on here must have professional detailing experience and could help.
