After 1000 miles the engine compartment has gotten kinda dirty. Was thinking about using some simple green and a hose to it. How do you guys wash it?

straight simple green in a spray bottle, foaming spray bottle works even better. Hot water pressure washer if you have one, next would be hot water through a garden hose/sprayer, last choice would be cold water through the garden hose but it thats all you have to choose from its better then nothing.
Make sure you clean the clutches too. Eric
 
open two place trailer and the car wash. can of engine greaser take off the belt spray the greasy spots down and let sit for about 3 min flip it on the side open the hood and hit it with the pressure washer.
 
At work; we use Super Clean (available at Napa, at least locally) on nasty fishing boat bilges, loaders and the like. It does a good job. The car wash tip would be great if you do not have access to a hot water pressure washer. Put the Super Clean on at home and drive to the car wash, do the wash and drive home again and toss it back in the warm garage to dry.

*Note most of the electrical connectors should be water tight; but I would not direct the pressure washer directly at the electronics. You may want to have the sled running while you do the wash, so if it hiccups (may have gotten water into something) you can narrow down where you were washing at the time and know where you need to start looking for the problem.

the super clean works awesome too but i don't like to leave it on for more then 2-3 min as it can discolor some of the plastics and be hard on the powder coat.
don't start it until all has dried not voltage to the electrical system and all is happy.
 
I use Super Clean in a spray bottle. It's way more aggressive than Simple Green. I spray it on at 100 % strength and let it sit for about 5 minutes then rinse with hot water. Never needed a pressure washer. I have a hot water hose faucet in my shop so I just use that with a regular hose nozzle.

If there is still some grease I just do a couple more soak cycles or hit it with a brush. I use this to de grease hoist parts on customer repairs some come in from a rendering plant which can get really nasty.

Never needed more than one soak and rinse on my sleds.

I won't use an engine de-greaser spray since it's petroleum based and I don't want that on my clutches. Same reason, I don't use the pressure washer, it's harder to control where the crap flies.

I'll usually aim a fan into the under hood area and just let it run for a couple days to get everything nice and dry.
 
Super Clean is awesome but nasty. Stuff will take your breath away if your spraying it in an enclosed area. It was also find any cuts or cracks around your finger nails and burn like a bitch! If you choose to go this route make sure you get it 100% washed off, anything left behind will just keep eating away at what ever its on and that includes aluminum. Eric

We use it for primary degreaser - great stuff but use carefully when undiluted as it will take your breath away esp in an enclosed space. Hard on the eyes & skin. I would also be careful with it around seals / plastics / fibreglass / paint - be sure to rinse thoroughly and don't leave it on too long. Recommend diluting it for light clean up and a little effort with a brush helps greatly as well.
We used to get in 5 gal pail at equipment parts retailer but now find it at Walmart in gal jugs (not quite as potent as it seemed to be in the 5 gal pails though). Always keep a stock on hand!
 
All the tech videos I've had to take over the years, it seems like isopropyl alcohol and a lint free rag is good way to go. Although, I have gone with Super clean, Carb clean, or some sort of brake clean and have had good luck. Spray it down and let it soak then spray off with a hose, or just wipe it down with a towel.
 
gunk FOAMY engine brite, not there regular one the foamy is milder and works really well without harming, we use it on the boat all the time as well, spray on let sit and pressure wash off

This is by far the best way to clean AND get your hands on every part of the under-hood area.
If something is loose or broken you'll notice it by cleaning this way.
High pressure is really bad for most electrical connections and seals.
Clean your clutches by removing them and taking them apart... I'm certain there are plenty of threads about how to do this and what tools you'll need.
If your engine has any polished aluminum on it using Castrol Super Clean will destroy the finish, if you get it on your tunnel you'll have a dull spot where it touched it. Don't ask me how I found out about this.:face-icon-small-dis
Get in there, use your hands, inspect everything that moves or makes a connection.
It's a long walk out of the hills or an embarrassing tow behind your buddy.
I could eat off my belly pan and it really doesn't take all that much time.


 
We have your laundry washer/dryer in a room adjacent to the garage. I always disconnected the washer and used the hot water! Works awesome with a pressure washer and really makes a difference when blasting away grime.

I have a pic that looks the same. Including the sleds. Towing sno be won out of gold creek. Looks like Shawn and his protégé.
