use gunk foamy engine cleaner, or motomaster engine cleaner (canadian only)
don't buy the heavy duty stuff.. it really hard on stuff.
go drive your car around the block to get everything a little warm, not blazing hot.
make sure you do this OFF your drive way... IE have your front end of the car into the road or park it on the curb.
take plastic bag and masking tape... stuff a bag into the air intake of the box or your cone filter.. tape it up..
take another bag and wrap your trailing and leading coils, tape it up.
also wrap the starter in a bag and tape it up.
this is so you don't get water into any of these... that is bad.
Now buy about 4 to 10 cans of foamy engine cleaner... 1 can is hardly enough...
spray all over the place...avoid your exterior paint.
don't worry just wash your car and wax it again after.
let it sit for 10 mins... VERY important!. then take a soft brush and brush the areas that are heavyily soiled. spray more on as you brush the area... let is sit for another 5 mins... (do this in the shade... not in the scroching sun)
then hose off very verry throughly.... very imporant... i mean very through...
then remove all plastic bags and start engine... car may be difficult to start due to water affecting coils and spark delivery.
let it idle for 10 mins or drive around a few blocks... to get engine hot to make water evaporate...
pop open hood and notice the sludge has barly come off... repeat again tommorrow because u'll be tired and don't want to do it again.
I've gone through 8 can of that stuff... and the car isn't even close to clean... i gave up...
i'll do it all again when i have the engine out next spring

I don't think that there is such stuff. The only good cleaners are the really strong ones that kill the environment and will eat a hole through your foot if you spill it. They'll tear right through the grime and crap, but you have to protect your goodies. 
Ever tried the enviro-friendly, gentle-on-yer-nuts cleaners, like that Engine Brite crap that Gunk sells? I have. You might as well try to clean your engine with cold cat **** for all the good it will do.
You can't have it both ways.

Simple Green also eats aluminum (which there is a lot of on our engines.) There was mention of an Army or Air Force study that found this. It was on a 7 site. I'll see if I can find it...

Re: Simple Green
It's Simple -- Don't Use This To Clean Aluminum
A well-known aviation magazine this month published a feature article on cleaning one's aircraft and getting it ready for spring flying. Only one problem -- a product the article recommended as safe for aviation use has been proven corrosive to aluminum. The product is Simple Green, a popular household cleaning liquid. According to the magazine's May issue -- which included a photo of Simple Green and other products -- the liquid "does an admirable job for a fraction of the cost of the aviation cleaners." While that may be true as far as it goes, both the U.S. Air Force and the U.S. Army have conducted tests of Simple Green and strongly urge that it not be used to clean aluminum structures. In one test conducted by the U.S. Air Force, results from which were published in 1989, aluminum alloy samples were immersed in Simple Green for a week then removed, cleaned and weighed. The results indicated that the approximately 3.5-gram aluminum alloy samples experienced a material loss of about 31 milligrams in a diluted solution and a whopping 295 milligram loss after spending a week in the undiluted liquid. The Air Force report summed it up this way: "We do not recommend the use of this product on Air Force equipment containing aluminum." Good advice, that.
