And a dremel with a buffing wheel, on slow speed, with a piece of rubber tubing around the metal shaft of the tool.

Non-scratch Scotch-Brite and soapy water using Dawn dish soap.

I would think polish of any kind would stain the black part and a polishing device would shred on the sharp edges. I would use a stiff brush during the washing process and live with the result.

Keep in mind that you will be scrubbing on aluminum. Start with the least caustic/abrasive products first, so that you don't make it worse.

That edge is so narrow, it will be next to impossible to use any kind of polish and not get it on the "black" part of the fins.

You don't want to get any polish on the Black for sure.

This works very well!
You don't even need any "polish", just a quick brush with the pad.
