I believe you have a mistake in your article on sensor size crop factors. I believe you should have the Nikon's as a crop factor of 1.6 & the Canon's as a 1.3 crop factor.
I have used blowers, brushes and wet cleaning on my 20D. No more! The Sensor Klear by Lens Pen (less than $10) works great and so easy to use.
