IN a pich, I've also used dishwashing liquid in my dishwasher. The dishes came out clean enough, but I had to wash them a second time, without soap, to rid them of soap residue.
The anodizing process protects agains oxidation (corrosion) and is used extensively in the military and government to protect aluminum parts for the corrosive salt water evinronment of ocean-based vehicles (D.S.R.V., ships, aircraft, etc.). The alkalye enfironment of the dishwasher will not affect the anodizing, just the dye that makes the pot pretty. The pan will still be protected from corrosion, and resist nicks and scratches to the anodized surface, which is made harder by the process. That's what the anodizing is about, protecting the relatively soft aluminum. It doesn't do anything for cosmetic appearance. That's what paints and dyes are for.
