For info, I use sensor cleaning swabs and cleaning solution (http://www.warehouseexpress.com/index.c ... rownb.html)
A word of warning though - Kodak and Fuji approve of the process but Canon do NOT! So you do this at your own risk ... the mirror dropping on the swab would not be good! So, if you b**ger up your camera, don't come running to me!!!!

I've used this kit on my 10D and 20D and I'm happy with the process, it just takes some nerve!!!!

It is worth doing a Google search on cleaning sensors using swabs just to get an idea of the best techniques.
Note that different cameras require different kits as the swabs are made to fit across the sensor allowing cleaning in a single pass.
Hope this helps!
(PS, forgot to mention, never use compressed air such as the small cans you use to clean keyboards, etc (and definitely do not go to the petrol station and blow the dust out with an air line!
