I had a chat with a museum curator that flipped my view on cleaning old lenses

I was fixing a 1950s Leica for a local history museum, and the curator, a guy named Frank, asked me to leave the cleaning marks on the front element. He said, 'Those tiny swirls are part of its story, like patina on bronze.' I've always aimed for flawless, but he argued over-cleaning erases character and can devalue a piece. Now I'm torn between perfect optics and preserving history. For you all, when do you stop cleaning a vintage lens?

It's like keeping the dents in a favorite old car.

A camera repair blog made a good point about this. Some collectors see cleaning marks as proof a lens was actually used by photographers, not just stored. That history can be more interesting than a perfect but sterile piece.

Yeah, that tracks. Next they'll be selling lenses with "authentic photographer fingerprints" at a markup. I can see the listing now, "minor fungus included for character, tells a story." It's the same logic that makes people pay extra for pre-distressed jeans. At least the jeans don't have haze that ruins your pictures.

Wait, Frank actually ASKED you to LEAVE the cleaning marks? That's wild to me. I've spent YEARS trying to get those microscopic scratches out of old glass with patience and the right fluid, and this guy wants you to just... stop halfway? I get the patina comparison with bronze statues, but a lens is a TOOL first, a display piece second. Fungus and haze literally ruin the pictures you take with it, and that's not "character" that's just a broken tool. So at what point does "history" cross over into "damage that makes the thing useless"?
