A method of use of a dusting tool for cleaning the exposed surface of a camera sensor lens in a recessed digital camera sensor chamber while avoiding contaminating contact with the side walls of the camera sensor chamber, the method comprising the steps of: providing a non-scrubbing duster member having opposite one and another ends, and a tuft of bristles having electrostatic charge built up therein; engaging the duster member inside the camera sensor chamber; operatively engaging the bristles leading edge tips onto the exposed surface of the camera sensor lens; and manually sweeping the dusting tool bristles leading edge tips over the full exposed surface of the camera sensor lens including the peripheral edge portion thereof but excluding contaminating contact with the side walls of the camera sensor chamber, while the duster member remains motionless relative to the handle.
