Must be because of some "anti-fog factor" protein coming from the kissing: ever been "glassy eyed" ? ---> ;+) Whatever, my diving lens was "way" better with such. Don't drink and dive, however . BUT: though i HAVE spitted at my lens(es) before, my favorite remains "steaming" (for lack of another English word -- "bu=E9e" in French ) my lens with my breath then gently rub with a Kodak Lens cleaning tissue, using a toothpick (with the same type tissue) to reach the very edge of the lens, gently, if required. Or Kodak Lens Cleaning Fluid if it starts getting on the real bad side of things or before a "project", doing all lenses in a row, before hand. Medical grade isopropyl alcohol is the stuff my photocopier days technician used to clean those problem selenium drums: the only stuff that left no traces and wouldn't CAUSE secondary problems. We actually went to an hospital to get a few bottles: much better than the usual commercial stuff; just about the same price. Even though the purity numbers look about the same, that hospital stuff is MUCH better than the discount pharmacy "variant" : my technician was the best around and wouldn't use any other stuff on the expensive and fragile drums. [PS: he didn't DRINK the stuff either...] Acetone, benzene and such, i'll leave to the pros. Yet, my eyeware optician uses acetone, but my glasses are NOT $1000 PLUS photo lenses... and have no fancy chemicals to cement the optical elements. Andre Jean Quintal Love one another.
