Tape of a nice square with some tape, make it quite thick and polishouders the inside with metal polish like commandant 4 (or any other). As the rest is het brushed, you wonââ¬â¢t get a nice finish anyway. So that would be the easiest way to make it tidy. Else you would need to polish off the top layer of the whole pot, which would even take ages with a polishing machine.
