The use round sticks, like blunt ****tail sticks about six inches long, they wrap a small strip of lens cleaning tissue around the end of the stick and dip the tissue tip in one of two or three dishes of solution, different solutions for different types of mark. They then address an individual mark or dust bunny on the sensor using an illuminated lupe to see what they are doing. A gentle blast of compressed air and on to the next mark. They did not appear to wipe an entire sensor on any of the cameras I watched two technicians cleaning. Indeed they didn't appear to have any of the spatular type cleaning wipes in their kit. I must have watched them clean perhaps 20 cameras and lenses that morning? They were very thorough, my D300S was immaculate after they had cleaned it.
