They`re very stiff indeed! It seems to me a lot of trouble to send the

I would Not be using cotton buds. They leave long fibers all over the place. There are proper cleaning materials available at most camera stores.


Why not search Google for "cleaning CCD"


which turned up thousands of sites with more info on this.
