Hi Scott,
I used to swear by the Arctic Butterfly for cleaning my sensor. But recently no matter how many times I tried to clean the CCD (actually the IR Blocking filter in front of the CCD) with it it just would not get every speck - and one speck I think was welded on! So I always recommended first - using a blower (with no physical contact with the CCD), then if that does not work then use an Arctic Butterfly, and if that does not work then use Eclipse fluid with sterile DigiSwab pads. I have always avoided the latter as a last resort, but in this case I had to use it and it was very easy and did the trick! Just follow the instructions.

Also I would not use the same cleaner/dust remover system that I use on my lens and then use it on the CCD - keep them separate.
Hope that helps - Willie
