Always turn the camera off when changing lenses so there is no electrical charge to attract dust. I always put the wind on my back too and mostly point the camera down. So far have only needed the Rocket blower except twice have needed tweezers to remove a hair that nothing else would pick up. It was not actually touching the sensor but attached at one end to the box and floating about at the other end in front of the sensor. Heart in mouth, take glasses off for better and closer close up vision, hold breath, remove hair and then let out huge sigh of relief. Having a household full of pets does not help!
