Have you tried an aluminum polish? Aluminum will oxide like most metals. Look at a new aluminum light pole, then compare to the older ones. Same process.

So periodic polishing will be needed to keep it looking like new aluminum. If the oxidation is light, then a manual application of polish may be all you need, but if it real bad, then you may need to use an powered polisher. Eastwood sells various polishes and application tools.

Also your local auto parts store may have aluminum wheel polish that should work for keeping it looking good after your initial cleaning.

I believe the correct finish is a "fresh cast aluminum" look as opposed to a shinny polished look.
