Truckers "acidize" their fuel tanks and aluminum wheels and it really cleans them up. I have an all aluminum 4.6 Ford for my 34 5w that has a lot of powderly white spots on it and also grey areas. I wonder if one could acidize it and clean it up? I'm sure there is a strength of solution to use and a time limit for letting it work. Anybody done this?
It should work but I would keep it out of the inside. Expect to get **** for using that motor in that car from pretty much everyone that sees this.
"acidize" do you mean clean? Is this going to be a complete engine or just spots? Just spot cleaning can be done with Simple Green cleaner or a stronger solution of Super Clean and water. Both will clean aluminum and remove the oxide. Just be careful with the latter as it will turn aluminum black if too strong. I used a chemical cleaner in my hot tank for years that cleaned aluminum like it just came from the mold. But our government EPA banned manufacturing the chemical. I changed to commercial Simple Green and it worked fair, but it was too expensive to maintain in a 300 gallon tank. A transmission rebuild shop should be able to clean your parts.
