Hi! Do you guys know a way how to restore the physical appearance of old lenses. I have an Olympus OM 50mm and it really looks used, not abused, but was definitely used a lot before. There is no problem with the image quality from the lens, I just want it to look cleaner, shinier perhaps. Thank you so much. I was looking around sites like lifehacker but I can't find articles about this. Thanks in advance to your replies.
