A. I wouldn't expect scale cleaners like Lime-Away ⇦ on eBay or Amazon [affil link] or C-L-R ⇦ on eBay or Amazon [affil link] , nor mild acids, to have any significant effect on nickel. Am I missing something?

A. You can use next solution:

Cold immersion,1-2 seconds!
Then rinse in running water and finally with water and alcohol(1/1).

Good luck!
