The saving grace here Nick is that left alone for enough time, polished aluminum will go back to dull all on its own. (Normally seat posts are not anodized BTW)

One interesting factoid: Anodizing is what aluminum would do on its own in a controlled atmosphere, in other words anodizing is a layer of oxidation... aluminum oxide. That 1952 La Perle Série Course Spéciale that I got a few years ago had been stored for 50+ years up high on a wall in a closed garage with a good roof. All the aluminum parts looked like they had been pearl anodized and were in perfect condition. Amazing!
