Once a year, unless you have a tokyo marui, then once every 2 years or until you notice it doesn't shoot as well as it used to.
However you should ideally clean your barrel after every game (if you have a tightbore), once a month if you have a stock barrel.
Pistols should be relubed once a month, whether you used it or not. Run a mag through it once a month during the winter to keep everything lubed, and store the mags with a little bit of gas in them.
Tamiya connectors suck.
