After several years of bouncing around in our dusty desert, Cookie's Canon 50D has some contamination on the sensor that's not responsive to jets of air or the in unit sensor shaker.
A little hesitant to go at it with Brillo pads and Comet Cleanser, but don't really want to ship it to Timbuktu and back either if one can avoid $100 minimum service fee and a similar shipping and insurance charge. Is this an ultra sensitive neurosurgery procedure, or can a neophyte accomplish such without much danger of irreparable harm?
Suggestions derived from experience would be appreciated.
Thanks,
