I've used canned air on my 300D a couple of times when a bulb blower wouldn't clear the sensor. My method was to mount the camera on a table top tripod. Place a half full can of compressed air flat on the table, give it a short burst. take a shot of the clear blue sky and look for shadows.
BE VERY careful not to get the liquid propellant to co come out of the can... I sprayed a x2 macro filter with a can of compressed gas and it got frosted over by the liquid. The filter was left with hundreds of small cracks around the edge. That is why I keep the can flat on the table and half full for the sensor.
