Hi Paul
I use the techniques on this
Digital SLR Sensor Cleaning website to clean my DSLR, DMK/DBK and SBIG ST7 and the method works a treat.
My personal experience with the photographic style lens pen’s, is that I have invariably found that at best, I only push the dust around or worse still, add more dust so I don’t use the lens pen for my CCD cleaning now.
Cheers
Dennis
