Yeah, there are probably a few things that work, but I've seen this one and it is remarkable what it takes off. But not everything comes off —and a good polish is necessary to remove the deeper white pits and other stuff. But once you start making it look that good, you're committed!
On the other hand, a lot of what you can buy is harsh acidic (like truck wash baths) that will whiten and change the surface and can't be brought back. If you use the right cleaner for brushed aluminum
or the cleaner for polished aluminum
you won't have that problem.
These are made in North Dakota from soy and corn, and are supposed to be safe to use, if that matters.
