I am surprised by the contents of your post Wilt. I did a Google search and found alot of knowledgeable/experienced people using Kimwipes on their lenses. B&H describes them as, "Kimwipes are disposable wipers designed by Kimberly Clark, that have a fine crepe surface that is super absorbent, strong, and nonabrasive."
I guess I'll check them out when they arrive and see.
The opinions on Kimwipes seems to be all over the place! In particular, there is ZERO information from Kimberly Clark. But consider the fact that they are a PAPER products producer, and paper is wood pulp, and a number of manufacturer's optics care publications allude to the fact that cotton is fine to use, but wood pulp-based products are NOT fine to use on optics. These instructions from microscope and telescope optics manufacturers, that I have seen in past searches.
If you look at the instructions from universities to its students in care and cleaning of lab optics, even that has differences of opinion from university to university!...Some say to wipe optics with Kimwipes; others say to wide the exteriors of equipment and perhaps to blot up exceesses of oils (for oil-immersion miscroscope optics) but to use LENS TISSUE with lens cleaning fluids (or very brief wiping with methyl alcohol so as to not dissolve the cements that hold the lens element in place). Kimwipe is lint free, and relative good for wiping up spills or excess fluids, so in the university student lab setting, it makes some sense for cleaning spills. My guess is that since lots of it is around, it got conscripted for even cleaning lenses, but at some universitiesthis was done grad student lab assistants who simply did not know better, and that legacy remains with us in some places. At other universities, more astute lab assistants knew better!
Lastly, I refer back to my previous comments about blowing my nose into Kimwipes in the past and how rough it was (and we all know about how abraided our noses get during colds and extended use of Kleenex or other tissues based on wood pulp!). Kimberly-Clark and wood pulp products are synonymous, so would you trust your lens coatings to their products? Finally, there was a published story in Pop Photography (or Modern Photography) many many years ago when microfiber was not yet readily available outside of Japan, where lens tissue that was cheap off-brand items was more abrasive to coatings than Kodak Lens Tissue which was more abrasive to coatings than microfiber when the surface was viewed under high magnification. So if the cheap 'lens tissue' abraids, dare we try Kimwipe unless we get some statement from Kimberly Clark about the freedom from wood fibers?
