Thanks, John Motts.  I know you're offering this in a helpful spirit, and that's appreciated.  However--and I ask this in the spirit of intellectual curiosity, not malice--how do you really know "it's not such a delicate operation as you might think?"

You say it's not a "delicate operation" because you're cleaning a filter in front of the sensor and not the sensor itself, which implies that you know the filter is "not so delicate."  How do you know how delicate or not delicate the filter is?


* What is the filter made of?  Is it coated with anything?  What?   Are the materials and coatings the same in every camera, or are they different?   Would different materials and / or coatings necessitate a different cleaning material or solvent?

* How do swab materials or cleaning chemicals interact with the filter material or its coating?  Do chemicals leave any residue of any kind?  Do dust and this residue interact in any way?

* Nikon tells us the camera's own internal cleaning mechanism piezo-electrically vibrates the sensor filter to loosen and shake-off dust; how does mechanically swabbing that dust and / or doing so with some kind of chemical solvent impact the piezo-electric "shake" effectiveness?  How might chemical residue impact its effectiveness?  Can pressure applied to the sensor filter damage its piezo-electric isolation or freedom of movement?  If so, how much pressure?

* If you were to damage the filter material or, if it has a coating of some kind, that, what impact would the damage have on image quality?

The Nikon engineers who designed the sensor and the filter over it can probably answer all of these questions with specificity, certainty, and data.  They know how "delicate" the sensor assembly is: they made it!  Which is why, when they summarize, "Under no circumstances," I don't disregard them.

But, if you can answer these questions with more specificity (and show us your data / sources), then do share!
