I am trying to clean some corroded aluminum. In my quest to find out how, I've stumbled across a lot of bewilderment and misinformation, and a lot of different feasible techniques as well.
My question is: How can I determine, on my own, whether something will dissolve aluminum oxide (room temperature) or not? Like, just by looking at chemical formulas.
I'd also need to be able to check to make sure a chemical that dissolves aluminum oxide doesn't also dissolve the good aluminum.
My goal is to be able to figure out not only if a given chemical will dissolve it, but also to come up with an idea of which chemicals that I don't know about may also dissolve it.
As a bonus it'd be nice to determine the temperature at which a reaction would occur if it's a bit higher than room temperature so I can determine on my own if I can apply a reasonable amount of heat to make something work.
I know very little about chemistry except a basic understanding that things react and can be described by equations, and that reactions absorb or release some amount of quantifiable energy.
Aluminum oxide is Al2O3.
Sorry I do not know how to tag this.
Also I'm not sure if "dissolve" is the right word. To be clear I use it in a way that means if I apply the chemical to corroded aluminum, it'll make the corrosion go away into the air, or turn back into aluminum, or at least make it easy to scrub or wipe off.
