So, i decided to wash my engine with only water and a sponge. I just followed instructions in other threads here on where not to let water go (like the air intake). I was kinda afraid because there's lots of electric plugs, the air intake, the alternator, the battery, etc and i have never done this before. It doesn't looks pretty clean, cab someone tell me if this is as good as i am gonna be able to leave it? If i can be less afraid of water? If i can really rub my sponge anywhere?
Doesn't looks like it was worth the effort. Maybe i need to do it a couple more times to get more confident about it?

Look at all the dry stick mu still in some areas that my sponge wasn't able to remove.

Tips & tricks welcome

 

I may be dumb for it, but I used a pressure washer on mine. I covered the intake, and just tried not to get the electronics too much. I then let it set for a few hours to dry. Haven't had any problems yet knock on wood.

 

Mine looks like that when I "clean" it I just used a normal hose though.

 

I am afrai that presure can help water get into the connectors or may take a cable or wire appart. I don't know. That's why i want experts help.
I think that the worst that can happen is that i have to wait a long period to be sure everything is really dry.

 

I just spray mine down with a hose and nozzle. Doesn't look clean. But gets the heavy stuff off

 

I've pressure washed my JK engine and others countless times and just avoid the intake and hold the nozzle far enough away that it isn't going to do damage. Haven't had any problems.

 

Pressure wash as said above avoid intake and hold a distance awat

 

Bingote, I was a Volvo Tech for 37 years and pressure washed more engines than I care to think about. These newer vehicles have electrical connectors with incredible rubber seals. Go to the market and buy yourself a spray container of Simple Green and take it to the car wash with you. With the engine nice and warm, spray the entire engine compartment down with the Simple Green and let it set for about five minutes, then start spraying with the high pressure soap spray. No need to use a sponge. Spray everywhere, including under the vehicle, then switch to the rinse water. I spray the alternator, battery, everything. Mud is the absolute worst thing to try to clean off any part of your Jeep, so try to get it off before it hardens into concrete. The warm engine compartment will dry pretty quickly. Just don't aim the water into the air cleaner intake. The engine compartment on my 2000 Wrangler with 162,000 miles looks just as clean as our 2011 Rubicon with 1200 miles. It'll get the same treatment. Hope this helps you.

 

I always taped off any electrical connectors/components and the intake when cleaning the engine. Get some Gunk Engine Brite or some kind of engine cleaner/degreaser, make sure everything is cool to the touch spray some on and let it soak for a few minutes, use a little elbow grease and scrub some of the crap off then carefully hose it off with a light stream of water (use a garden hose, pressure washer isn't nessecary).

 

Thanks been waiting for a pro to answer! Now I got to get myself some simple green
