Unfortunately, anodized surfaces don't clean well. In fact, if you scrub or polish such a surface all you will get is a shiny drab-looking finished product. In order to properly clean and polish aluminum you have to de-anodize it.
Sounds difficult, doesn't it? After all, the anodizing process requires acid baths, cleaning steps and electric current, not to mention timing equipment and dyes (for those colored surfaces like brackets, etc.) One would think, therefore, that de-anodizing would require the same materials, only in reverse order.
That would be nice and effective, but it turns out that aluminum is one of those metals that can be chemically de-anodized. All you need is the right chemical, and you can find it in your grocery store. The "magic" chemical is sodium hydroxide, and it is the active ingredient in drain cleaners (Drano). It comes in liquid and crystal form and we find the dry crystals are the most effective (and least expensive.) All you need to de-anodize your piece of aluminum is a shallow pan large enough in which to lay it. You'll need warm water, rubber gloves, eye protection and, of course the drain cleaner. Fill the pan with enough warm water to cover the piece and then add enough drain cleaner to do the job - we find that 1 tablespoon of cleaner to one gallon of water will de-anodize a couple pieces like headlight bezels.
and then you could powder coat it, then worry about taking the powder coat off the bearing races!
