What do you use to clean up filiform corrosion on aluminum window lower sill?

This is on a family elderly family members house in Germany.    1978 built block with those nice Feinster Kaup windows set in the block.    I have a hard time as I cant read the technical stuff, same with communicating with clerks and of course their stuff is just different.  Add to it very little choice in shopping for materials makes everything primitive and painful.                                           

 0k the sills are just starting to corrode.   No big deal just cosmetic do far but they need some sort of polishing .    I knocked down the raised stuff and it cleaned up ok .   So what do you use to keep those sills semi shiny?     Brasso, Magic Wad , or what?    I do have some old left over airplane polish for aluminum maybehmm 




If it doesn't move paint it..

Here are a couple of sites to look at for info; I found them by "googling" Cleaning and maintaining aluminum window frames.  There are quite a few things to read there.

In my experience, a regular maintenance regimen is absolutely necessary for keeping aluminum surfaces that are exposed to the elements sound.  After the first time of cleaning and protecting, they must be maintained regularly, say every three months, or more frequently if exposed to high moisture or salt environments.  A good cleaning and removing all traces of corrosion, and then sealing with a wax, like automotive polish and wax, and repeated as needed will go a long way to keeping aluminum in good shape.  I worked with aluminum in environments from coastal, right on the beach locations to extreme desert and high mountains that got a lot of snow, and we did regular maintenance to keep things viable; replacing stuff was not easy or economical.
