What's the trick to getting the engine case  sparkling clean when rebuilding
?  I have looked into this locally and have  been told by two engine
rebuilding machine shops that the chemical dunk tanks  they normally use are not good
for aluminium.  The chemicals they use will  turn the aluminium to mush they
say.  They also say there is no  aternative other than pressure washing or
perhaps oven baking.  I have  tried various engine shampoos and pressure washing
but the corrosion from oil  and salt deposits on the cases remain.  I think
there must be a chemical  alternative.  Anyone with suggestions please ?
Cheers,
