I am about to re-anodise one without dye - aluminium will eventually oxidise and dull. It's quite slow, and the bits you handle will probably stay bright.
You can remove the previous anodising with sodium hydroxide (drain cleaner, oven cleaner) then move on to finer wet and dry

This would probably have my ocd through the roof, what a fingerprint magnet. Looks nice though.
