   By mild abrasive, something like a pencil eraser. Not sandpaper and   
   never steel wool. Caig De-Ox-It on a paper towel or Q-tip also works well.   
      
   If by flux you mean soldering flux, not a good idea. Flux assists solder   
   flow, it isn't a contact cleaner or tarnish remover. Many fluxes will   
   damage electronics if not removed after soldering.
