Removing HEAVY oxidation from Jalousie Windows

[bass-o-matic]

I took apart one window. Setup my bench grinder with a buffing wheel and some Rouge and got to work. I realize now this will take AGES and there may be parts I can't get to. Additionally, I have spots of crud that take awhile to buff off.

Question. Is there some Safe trick for getting the majority of aluminum oxidation off Jalousie windows? Some wash? Chemical? Oil?

The only interesting this I saw on the InterWebs was this guy rubbing Marvel Mystery Oil on Aluminum motorcycle parts a day or two before to soak off a majority of crud. I like that idea.

Just want to make sure I'm not missing anything.

Thanks!

Pics of my progress attached.

I'm not familiar with any Jalousie window like the one you have but if it's not too thin maybe a bead blaster or soda blaster would help? I know after the windows on my '61 project I'll be going for some blasting solution rather than endless half baked grinding solutions.
