Thanks very much guys, I promise to look after my gun better from now on!

Hello there, This is my first post on the forum after lurking about for a while (so try not to destroy me over a simple question) and I can't seem to find a post that deals with this question through the search engine. I'm using a springer to hunt (gamo shadow .22) and the barrel and some of the other metal parts are getting a few rust spots. What's the best way to clean the metal work without ruining the blueing on the gun? I was looking at some Napier and Bisley gun oils but they seemed more aimed at bore cleaning and I'm not interested in cleaning the inside of the barrel just
