I've been getting tired of all the gunk on the sensor of my 10D. Both before and after images were shot with an 24-70L focused at infinity.

All those flecks visible in the photo are bits of dust stuck to the sensor. This evening I went to work on the sensor with a couple Sensor Brushes from Visble Dust. It took three tries to get most of the gunk out.

Not perfect, but really pretty good. Also used their Chamber Clean swabs to get some dust out of the camera body. There is only one spec of dust left under the focusing screen. I think I'll leave that one in there.
