As some of you on here may know I am a professional photographer. Being honest the best way is to take it to a good photographic repair shop they will do it while you wait, and it will cost somewhere about £20. On the other hand you could do what I do, which is either use foot bellows with the camera upside down for a quick burst of air to move dust around. The other cheap option is to use Lighter fuel and a cotton bud. Ive done it hundreds of times but for the fist time or two you have to be brave!!!!! if you want any advice send me a PM, and I will go through with greater detail!!!
