Back in the '60s I did consulting work for United Engine Rebuilders in New Brunswick, NJ trying to find and optimize a single hot-soak cleaner for aluminum engine blocks, among them Corvair, VW and AMC. The alloys they used were so different that there was no single "magic" juice for the job, what worked OK on one alloy attacked and etched the others; in the end they stuck with solvent cleaning.

A superb solvent method was to use a vapor degreaser with trichloroethylene, something that thankfully for our health the EPA has long since put to rest. But it was just an absolutely marvelous method.
