It looks like whatever spilled oxidized the aluminum. You can find an oxidation remover at any Marine supply store, probably some hardware stores too.
For the exterior, here is a copy and paste of a previous post of mine. Everyone may give you slightly different advice as there are many valid ways to do this. This routine has worked very well for me for many years.
It sounds like a lot of work, but once I got the process down, I found I could do all of these steps on a entire 23' boat in less than 4 hours, and it leaves it looking like new.
Edit: I forgot to mention, for the outside of the windows I like this stuff. It cleans as well as a normal glass cleaner, and causes any water that hits the windshield to bead up and run off. This is a nice bonus for many boats as they often do not have windshield wipers.
