Removing etching (?) from interior aluminum trim?

[exi]

Recent owner of a CPO M850i coupe.

There are a few areas of stained or etched interior, aluminum trim, demonstrated in attached photo, that do not clean off with typical quick detailer interior products.

Seems like somebody used an inappropriate product, but I'm not sure.

Before trying more harsh things, wanted to check in and see what was most effective for folks these days. Formerly spent a lot of time detailing cars when I had the time to do so, but I am not quite up to speed on most recent/best products lately.

(Also a few areas of staining on interior surfaces, like the glove compartment panel, also stubborn to remove; currently preferred products there?)
