Hi, I was cleaning the 350D, when my cotton bud (which comes included with my purchase of a cleaning kit) with lens cleaning solution on it, touched the mirror accidentally. The mirror changed colour, and soon emerged into a watermark. I tried to wipe the solution away, but the mark is still there..
I would like to know:
How can I do about it about removing the watermark on the mirror?
How much does it cost to clean and solve the problem through Canon Service centre? (The camera is still under warranty, by the way
