We are attempting to clean a small ceramic substrate for some testing here and one of the steps will include a pure water rinse to remove polar impurities after a prior isopropyl alcohol scrub which is done to remove non-polar contaminants.
I have received conflicting input relative to the cleansing effectiveness of distilled water vs deionized water. Seems to me that the distilled water should be more pure than the deionized water and leave fewer residues. Can you advise? Thanks in advance.

I agree. The wikipedia article on this http://en.wikipedia.org/wiki/Distilled_water
agrees with what I know about it. Distilling is a more broad-spectrum impurity remover than some other deionization methods, especially passage through an ion exchange column.
