I use a new 10cc syringe with a 23-gauge hypodermic needle to clean the image sensor of my DSLR. With a little practice, I can control the force of the air going inside the digital camera with precision. And since the needle is sterile, I am assured I am not blowing any dust or particles into the camera. The needles are cheap and available in drugstores [over the counter in most states; mail order in others], but, careful! They’re sharp!
