I looked at my 20D - two 1/2 months old - for the first time. I took a
shot of the sky and was amazed at the crap on the sensor. I ordered a
sensor cleaning kit from Copper Hill Images, after hearing about it on
this forum. I hope it does the trick.


Also look at

method using the Sensor Brush method has become the preferred method of
many
professional photographers.


I bought a Sensor Brush and it does work. I have no affiliations with the
comapany except being satisfied. It IS expensive, but I have two cameras to
clean, my daughter's and mine. Took a few minutes and was totally
effective. I was a bit leery of the swabbing with wetted pads but this dry
method does work.
