I was handed a nice Canon Canonet today by a friend who knows I like to dabble in repairs.
The camera is in good condition except for the non-functioning meter (most of them die anyway) and the rear element having very strange white deposits on the rear element. It certainly doesn't look like fungus; more like calcium deposits. The patches actually are on the surface of the rear element facing the film plane and they are rough to the touch.
I have started with alcohol, went to half and half peroxide and ammonia, then to acetone and am now soaking it in vinegar. They have dulled somewhat, but are still there.
Kind of at a loss as how to proceed...
Suggestions?
(sorry for the dirty fingers!)
