++
If I leave a piece of steel in
Alodine tank, it will effect
aluminum parts and contaminate solution?

You are asking about a specific proprietary product, so you should
get your answer from the manufacturer of that specific proprietary.
However, were you to ask the same question in generic fashion, I
would have said that I have actually seen chromate tanks built of
plain steel--so it should not be a problem.

Alodine 1200 and
equivalent products such as
Iridite 14-2 contain a
small amount of complexed ion. So that the solutions will test
positively for iron. However a large excess of uncomplexed iron is
detrimental to the salt spray results. So it depends on how long the
iron object was in the solution.
