what shall i do?
Then you must have both a dirty mirror and a dirty sensor. A dirty mirror won't affect the pictures and is probably best left alone unless it's really apparent and bothersome when you look through the viewfinder. With the sensor I prefer the blowers as well. I would be hesitant to use anything that physically comes in contact with the sensor.
