Hi Kubur, 
 
my favorite method is very simple. Just applying a thick layer of Ballistol-oil onto the rusted surface and wait. Once a week replace the old oil with new one. After a few weeks or months the rust slowly disapperars by itself.  
This is the mildest method I know.  
I would not recommend to use transparent lacquer, because it can rust under the lacquer.
