Blue/green corrosion

  1. Hi,

    I've recently acquired a Canon P as part of a haul from a local garage sale. It has these interesting blue/green spots all around (I believe it is verdigris?)

    Is there an easy way to safely remove this? Does verdigris spread over time?

    Thanks in advance,

    John
     
  2. You might try vinegar with a little alcohol, but i'm not sure of the intensity of the spots.

  3. Just a few spots on the exterior. Does this spread over time if I'm not careful in removing all of it now?
     
  4. It will only spread if the camera is kept in a damp environment. You only normally see it on cameras which have been poorly stored over a long period.
     
  5. I’ve seen many Barnack Leica's like that. Normally stored in their leather case in a humid environment. They typically smells musty.
    It won’t spread if used and kept in an airy place. Don’t keep it in a leather case.
