Up here in canada i can buy a 2 1/2 gallon of Zep Purple Industrial degreaser at Homedepot for 30 bucks, i dilute it by half and it is still way better than any auto parts store crap they sell. I also used a product similar called purple power but not sure where to buy that... it was almost as effective as the Zep product.

Spray "Gunk" on a warm engine and let it soak a while before hosing off. The spray gel will stay longer on vertical places, but the reg liquid will get into the tight spots so a couple cans of each works best.

For something less nasty that still works, I like a product called Oil Eater. It's not nearly as good as oven cleaner, but then, it doesn't eat your lungs out either.
Zep products are good- but yes, I wouldn't want to bathe in them, either.
Honestly, I have never found anything that works better than a putty knife on really heavy grease. Once all the caked- on goo is off, then the chemicals come out.
fwiw,

Tried them all at one time or another. As Brad suggested a pressure washer is best. If not, by far the best one I have ever found is LA's Totally Awesome Cleaner from the dollar store. Don't dilute, let it soak and use a hose.

Thanks for the recommendations guys.
I plan on taking out the zf for a rebuild in the next several months and its got a nice layer of gunk on most of it, so while I have it apart I wanted to de-grease and paint it and also tackle the cross member as it is covered in old oil.
I don't have a pressure washer but what I had in mind was spray some type of de-greaser on it then take it to the car wash and hopefully remove as much gunk as possible.
Also another option is find somebody that has a heated washer like diesel brad had mentioned to remove the heavy stuff then de-grease and paint it.

One very slow day in the .mil Sarge sent me to the motor pool to clean off the engine in a 5 ton, they had this industrial high temp steam cleaner pressure washer, about the size of a small car. That thing was amazing! They're probably illegal by now, but they work great.

A note about any of the purple acid based cleaners.
Don't get it on good paint that you can't wash off instantly because it WILL etch.
Spraying it on & high pressure wash doesn't do much much even after soaking.
You need to spray a small area & use a really stiff brush to work it into the grease so it will break it up when washed.
