I used Happich Simichrome for years. Really an excellent product. Expensive in the larger container. Lately, I have been using a container of Mother's Mag and Aluminum polish as it seems to be the same stuff and really inexpensive. I also have a can of Nevr-Dull aka "aircraft wool." It's a wadding that you tear a piece off of and then wipe it on brass, copper or aluminum.
In doing large surfaces like an aircraft cowling that has a lot of corrosion, we first use phosphoric acid (never muratic) until the corrosion is totally gone (that make take a while) and then give it a quick alodine solution rinse to convert the aluminum's surface. No fume problems with the phosphoric but should wear gloves and protective glasses even though it's pretty mild stuff. Home Depot has the phosphoric but may be hard to find in the store.
