    Ever see a person use their t-shirt, after trying to find a clean area, to clean their lens? :o

    I don't know about that "spit not being abrasive" part. They probably haven't met my mother-in-law...

    The enzymes in spit are good to 'dissolve' Algae (= biological sells) and skin grease on lens elements. I have 'saved' an enlarging lens from algae by keeping the element in my mouth for a wile, then cleaned it wit the Zeiss kit and assembling. I learned the trick from a former, retired, Oude Delft engineer who, a long time ago, ran a camera repairing shop in Leiden.

    Santé,

    Now I have advocated the use of lens cleaning tissues, I must add the following caveat after reading of a post that advocates the use of facial tissues. Facial or any form of hand tissues from your supermarket are a big no-no. Believe me I have used them in an emergency. They do leave lint all over your lens just as Schneider says - and goodness knows what chemicals are in them that are not good for the lens coatings.
    I advocate lens tissues - but only those made for the purpose. I always use lens cleaning fluid - Tiffen for example - 2 or 3 drops on a lens. I recently bought a lot of bottles with a spray top, I think Leica, but they spray far too much fluid. Just buy ordinary bottles and use a few drops of fluid. Remember when you have no lens fluid, just spit on your lens - it will not hurt it. Before using any of the above, blow and/or lightly brush off, any obvious particles. Good luck and in the end everyone has their own method. I've used the tee shirt method on many occasions, but it ain't good for the lens - there is no way I would do that to my LF lenses.

    Most important... always blow the lens as clean as possible with clean air first before wiping

    Next important... never scrub a dirty spot off, always use very light wiping.

    Next important... never try to wipe off a dry lens, always at least have breath vapor if not good lens cleaner and always use just a little lens cleaner, don't just squirt a bunch on.

    And my secret cleaner that isn't really a secret, after blowing the lens off, stick a piece of Scotch Magic transparent tape to the lens. You can get a lens sparkling clean with scotch tape. I have done it to many lenses with no damage ever.

    Definitely make sure there's no dust/grit on it before wiping.
    If you take a lens cleaning cloth (I like plain unlotioned unscented kleenex personally, actual 'lens cleaning tissues' usually suck) and fold it so that you have a folded edge that you can grasp between thumb and forefinger.. use that to gently wipe the lens. Not smash/press it down with the force of your thumb, just let the tissue paper gently pass over the lens with the force of the folded tissue. I guess i'm not so good at explaining this but it's good advice nonetheless.

    Also, Rexton Optyl-9 is a product that I will forever be in love with. From cleaning CRT's, DVDs, scanners, my face (seriously), plastic and glass of all kinds.. it is absolutely the only cleaning solution I will use unless I need to break out the ammonia and drop of photo flo for things with mold, etc.

    NASA apparently uses it. It's really good stuff, no harsh alcohols or anything. Leaves no apparent residue. It's awesome. A light spray or a few drops is all you need, a tall spray bottle lasts a long time.

    Their negative cleaning solution is pretty good too but the optyl-9 is w here it's at.

    *shrug* I guess i'm getting some good plain tissues over here. I do shake them to free any dust or otherwise but they come fine (no dust or lint).
    Though i've never used zeiss tissues or the like.. I've used paper towels to clean condensers, etc. Works for me. No scratches.

    There are special tools to help install or remove parts like this which are essentially a rubber band that grips all the way around the filter, just a rubber band can work wonders though in getting filters like this off without any damage.

    Weirdly, looking for something else entirely but remembering this thread, I happened to notice this:

    "we've introduced a new top grade lens cleaning solution- 'Ultra Clarity'. Zeiss Optics likes it so well, they private label it."

    There is so much truth in this comment, at least in my view, and it could be applied to many, many threads here - not to mention discussions anytime, anywhere that two or more photographers are gathered together!
