There's another better and cheaper way and also crazy way to clean away dust from your sensor. If you are crazy enough to do it....
There's this product from Germany called Discofilm. It's a water base gel which you need to spray onto your sensor and after it dry up, you remove the layer of film from the sensor and all remaining dusts will be embed onto the film.
