Hoppes M-Pro 7 Gun Cleaner - 4 Ounce Spray Bottle - 070-1002

This product is one of the few that really does everything it says that it does. I use this on all phases of cleaning my pistol (a 9MM Beretta, which has a few places near the ejector that I have to ensure to remove residue) and it works flawlessly. It also leaves a light film that lubricates the area and thus can save some steps in those parts of a pistol where you don't necessarily need oil, but want to have a little lubricant.

Gets it like new clean!
