When using compressed air, make sure you give a good squirt or 2 into the air to get rid of the wet stuff that comes out if it's been sitting around unused for a while.
When the air comes out clean and clear, that's when I use it on the CCD and I haven't left any wet deposits yet..
That latest Saturn is even better CH, top stuff!
