Kenneth, getting dust on your sensor is a part of living in the real world. If you are interested in photography and using different lenses then learn to expect dust on your sensor and learn how to deal with it.
Here is my own method - proved and successful in my hands!
1) Go to your camera menu and raise the mirror.
2) Use a blower.
3) Still Dust? - use an "
Visible Dust" sensor brush (see visibledust.com).
4) 99.9% of the time problem is solved.
5) Still Dust? - use "
Visible Dust" swab and cleaning fluid.
6) Close the mirror (switch off camera).
No I am not a salesman for this Company - Yes there are other methods that work equally as well - but this is the way I personally am happy to deal with dust on the sensor.
It also permits me to change lenses in less than optimum wind/dust conditions without qualms.
