Before that I used to clean sensors all the time with this gizmo called SensorKlear - which is I think the easiest way to do it. Remember that in most bodies all that you are cleaning is the anti-aliasing filter, not the sensor, which is relatively inexpensively replaced even in the unlikely circumstance that something should go wrong: http://www.lenspen.com/?resultType=category¶ms=16&tpid=0&tpid=322 This is how you do it: http://www.lenspen.com/how_to_use/dslr_sensor_cleaning/ I still have these on hand for emergencies in the field...
