Attached Link: Cleaning CCDs by Thom Hogan

The link provides a very detailed description of how to clean the photosensor in a DSLR. After reading that material, please choose *one* option: (1) Ack! Eep! Gack! I don't ever want to touch that! conclusion: Perhaps a DSLR is not for you. (2) Hmmmmmm ... whenever I change the lens, dust may get onto the image sensor ... it can be cleaned ... it must be done with care ... it takes special materials. conclusion: I will have to live with it.
