Nickel metal cleaning

Q. We have a nickel surface that is tarnished. We would like to find a cleaning solution to remove the oxides from the nickel. We've tried a dilute solution of sulfuric acid, and we're also going to try other dilute acid solutions. What else can we use?

A. There are a couple of ways to remove the oxide. If you have current a cyanide/caustic solution should remove the oxide. Also you could use citric acid ⇦ on eBay or Amazon [affil link] to remove the oxide.
