Dirt seems to stick to plastic engine compartment parts the most. These would include plastic wire loom sheaths, plastic fan blades and other various plastic engine compartment parts. Please recommend a spray on type cleaner that will dislodge the dirt without melting the plastic that I can rinse off with water.
 
I use Orange Blast cleaner/degreaser. It does not harm plastic, paint or metal. You can find it in the automotive section at Wal Mart.
 
I've had really good luck with Simple Green....have used it on all my engines and it's never hurt anything, and is a great degreaser. Made the mistake of cleaning one engine with Bleech White....completely removed the clear coat from the intake plenum.
 
Thank You to all of you guys for the great suggestions. I'm assuming that you use the Orange Blast and Simple Green straight undiluted right?

Simple green will dull some plastics. I still occasionally clean my engines with it.
 
For plastic -- I use Stoner's Trim Shine -- and love it. I found this recommendation on one of the "detailing" sites. You can spray -- and walk away. With Trim Shine -- you don't have to wipe if you do not want to. It provided excellent results on both my vehicles.

That sounds like a real winner! That is what I'll uses once I get the dirt film off. Then maybe after I apply it, dirt won't stick anymore.

Try the Simple Green automotive flavor. It does not etch aluminum...
 
To clean, Simple Green either straight or 50/50.

Gunk Citrus Foaming Engine Cleaner works well for the whole engine compartment also.
 
Ditto the Simple Green automotive. Regular formula etched Aluminum and turns it a darker shade.

The foaming stuff in aerosal cans is scray stuff, it works, may be too well. Would be my last resort for super gunked motors.

Just for the heck of it, when I was changing the oil in my Chrysler this weekend, I sprayed all my plastic parts under the hood with tire foam and just left it, same as you do with the tires. Wow! After an hour it looked better than it did new. The black plstic intake manifold really looks striking. It's got a satin gloss to it now that it's never had.
 
Here's a pic I took this afternoon. As stated in my previous post, all underhood plastic parts sprayed with ordinary tire foam (Armorall brand I think) and just left. That was two days ago and it still looks great.

Looks good G-man. They sure wedge that engine in there! Don't think I could even slip an hand in beside that engine.

Sure is different than they made them in the old days. I think I could put 4 basketballs in the engine bay of my early bronco and still close the hood! Of course, it's not the pinnacle of engineering or efficiency.

Yeah, I was quite surprised at how good that turned out, especially given that no effort was involved. Just spray on and forget it.
 
I like to clean and degrease with straight Purple Power. After the engine is dry I hose it down with an entire can of whatever tire foam is cheap. That process even gets rid of red mud staining.
