Good topic. I have a pair of Leitz Trinovid 8 x 20c very compact, nice for carrying. I got them from my father and sent them out for servicing--cleaning, etc as dad had used them fairly hard and they were a bit foggy. They came back only a little brighter. I am wondering if once they get into that condition (maybe from bringing them indoors after being out in the cold) if they can ever be restored to their original clarity.
