Maybe other GreenKeyers could respond and advise me what I should get and how to use it.

Use a business card cut into strips with Caig De-Oxit on it. Hold the strip in the end of the needle nose pliers and push the contacts gently closed.

The burnishing tool is a bit like a nail file but not abrasive - it’s surface is nubbled but it will not remove metal.  It’s about a quarter inch wide and three inches long.  
This web site offers them at $3 each: GC type 9338.  Gogle-ing “GC 9338 will bring many other sources.
