Aluminum cleaning

If you can find it, MAAS metal polish works very well. I used to use it to clean up that kind of corrosion on straight razors, which are made of high carbon steel, but it should work fine on aluminum, too.

MAAS can do miracles certainly, it costs 12.95 dollars in the U.S. though. In Hungary I cannot get it, no one shop sells this product, which I find a bit expensive comparing to the lens' price..

Based on that picture - I'd just live with it.

I am attaching an other picture which shows more corrosion. If I could clean the barrel, why I would not try to do it? I am keen on doing my best😎

Something else to try. Moisten a cloth with lemon juice and sprinkle some salt on it, and use that to clean the oxidation. This works on aluminum pots, so it should work on your lens.If you don't have lemon juice, any mild acid should work.

I'll second using just a dab of toothpaste...just remember a little goes a long way.
