Use Pec Pads they are non abrasive and lint free..... any thing wiith lint in will scratch fine surfaces
Hello! We're talking about lens contacts here. Those are them brass-looking metal things. You know, the things that are designed to rub against other brass-looking metal contacts several thousand times. You could clean them with steel wool, indeed, steel wool would probably do a better job of ensuring a proper electrical contact than gently wafting a Pec Pad over the contacts.
