I have the full Visible Dust Arctic Butterfly cleaning kit including the inspection loupe and I was trained how to use it to remove dust and clean the sensor. I've had 5 cameras since I bought it, D90,D700,D7000,D800 and a Nikon 1. When I learned the correct way to change lenses (tilt the camera forward towards the ground", I found I was using the cleaning kit to clean the sensor less and less. I have a feeling however, as the Nikon 1 doesn't have the luxury of the mirror, this may become a more likely candidate for cleaning.
I do however use the butterfly regularly to clean the mirror area and internals to help prevent dust entering the sensor chamber.
Dust is dust and there's no way of eradicating it completely, where there's static, there's dust. However with care there are ways to prevent spits and spots getting on the sensor.
