Nearly 17 years of leaking oil my "new" truck was just caked with baked on grease, oil and dirt. 360-380 compression range wasn't really enough to warrant a rebuild... but I HATE dirty oily engines! STEP 3 after pulling motor & tear down CLEANING. Besides just oil sealing she is getting new rings bearings lifters etc (yes, I'm reusing the cam, crank and pistons). After spending all night friday and all day/night saturday plus over $100, soaking, pressure washing and scrubbing and NOTHING was working to get the aluminum clean! I even tried using the block heater to boil the parts that too was a no joy. Sure I could used stiff wire brushes but I didn't want to scratch the aluminum this is my truck not a customers!
I FINALLY found a way to get alum parts really really clean! The stuff machine shops can't put in a tank of acidic/caustic solution.

I take it you did not try Extreme Simple Green Aircraft and Precision Cleaner
I have used it to clean a dirty intake and it even removed the gunk on the inside of the intake.
I did use the pressure washer under water to blast things off.
The nice about this product is it won't cause hydrogen embrittlement.
It also leaves a very clean surface.
