There is so much misinformation on ccd cleaning out there.
A CCD is a delicate device so any contact risks scratching or oil smear.
I use Electrolube EAD400D Airduster in a pressure pak for my Nikon D100 and it works fine.
Just blow the dust away but give it somewhere useful to fall to , like down and out. Double check that the can you are buying is only pure gas, not the lubrication type!!!
