A water spot (on anything) is the impurities left behind when the water evaporates. Think of it like baked on dirt. You'll have to clean it first.
On bare aluminum, it also includes corrosion from the oxidation reduction reaction of the water on the aluminum. Once it's clean you'll have to remove the corroded/pitted/rusted surface, and get down to a new clean smooth surface.

The bottom of my aluminum hood was stained with coolant. I hit it with Scotch Bright pads and polished it with Mothers Aluminum polish. It did the trick.

Pretty much gotta sand it out (use a Scotch brite, or whatever).
Don't use kitchen pot and pan cleaner, ask me how I know  .

Kinda like others have somewhat said....polish,polish and repolish. Instead of a quick wax on a painted car, you'll have to polish. After you polish though, you need to apply an aluminum sealer to help the shine last longer. Messy job.

I would recommend polishing the spots out with Nuvite "S" grade metal polish with a fleece wrap. You can acquire both from PerfectPolish.com.
Good luck!

I had some major water spots that were calcium deposits on my tonneau cover and body paint (SPF Fiberglass). Regular old Vinegar removed the spots very nicely. I don't know if it would be different on aluminium, but I wouldn't think so.

+1^ Before any type of abrasive. Vinegar removes almost all of those spots because they are calcium deposits left when the water evaporates. The vinegar dissolves the calcium without abrading the surface. This is a much preferred solution.
