hi guys,
i tried to search the forum but i'm not that lucky enough..
well, i have a few barrel lenses (petzval, dialyte, russian lens).. the glass elements needs cleaning. since these are old lenses i'm hesitant to clean them.. do you guys have proper way on cleaning old barrel lenses especially the glass elements? what kind of liquid solution / tools are you using for these kind of lenses?
thank you very much!
