I cleaned my Nikon D600 sensor for the first time since December 2012 when I bought it. I am aware of the talk about the self-generated dust, and that was the case here. It started appearing almost immediately. I followed the advice of leaving it to around 2500 shots when it usually stops happening before cleaning the sensor. I used a light loop with a side opening. The dust was easily removed with an anti-static brush only. I did not need to use any of the other gadgets I have nor did I need to do a wet clean. I will let you know if it would start collecting dust again.
