Clean as often as you feel you need to. But inspect frequently.
Oh, and while you're inspecting, you might as well clean it.
I concur. Think of it this way: A firearm is a tool
made of finely machined and fitted mechanical parts. This tool is designed to hold and fire explosive cartridges that generate tens of thousands of pounds of pressure. The explosion of these cartridges generates a lot of combustion products that foul the tool's mechanism and are abrasive to boot (meaning that they can gum up the mechanism and also contribute to wear on the finely fitted machined surfaces).
It therefore makes good sense to keep your firearms scrupulously clean and lubricated. Modern guns may be designed to tolerate a lot of abuse, including shooting them without cleaning, but that is not a good reason NOT to clean and lubricate them! One could argue that "too much" C&L can be bad, but if you use common sense and modern cleaning tools/solvents/lubes you will NOT damage your gun.
