the zeiss wipes are just cheap alcohol wipes, nothing special. zeiss really whored their name out on those.

Well, they're only six cents a piece when bought in boxes of 400. Isopropyl works well on glass lenses.
My main concern was the older coatings though. Anyone aware of a good reference, you know, like some old German lens repairman?
I looked up the MSDS on that ROR stuff.

The key is the blower and the brush. If not used properly, you will be grinding the glass with the dust with, with paper, microfiber, or any other cloth used to rub it, leaving those "cleaning marks" that are really scratches)

Once a year I run all my lenses through the washing machine, whether they need it or not. I use the "Delicates" cycle. Don't want to overdo it...
The lenses that need the most care in cleaning are the early single-coated lenses, 1945-'60 or so. The early coatings are pretty soft and loosely attached.

Suggest not using any of these microfiber lens cleaning cloths or similar wipe.
Consider for a moment highly abrasive stuff (usually microscopic and not easily seen with the naked eye) that can easily end up on the surface of a lens is ground into the lens surface when pressure is applied to it using most any wipe, cloth or similar cleaning device.
Years ago when I purchased some new Schneider lenses, they included a microfiber cleaning wipe. It has never been used and never will be used.
Consider using this lens cleaning method instead:

Consider for a moment each step of this lens cleaning process and why it makes sense.

Sorry Bernice, a clean micro fiber cloth is the best way to clean after any loose debris has been blown off the lens.
Lens tissue, like
Kodak is made of silicon fibers that will create microscopic scratches.
Never agree on this. Simply consider what happens when any two physical objects are forced together..
When the microscope and other optical folks refuse to use these cleaning cloths alone there are very real reasons why they do not use them.

One more lens cleaning note from Leica Microsystems.
https://www.leica-microsystems.com/f...s-Flyer_en.pdf
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Remove attached dirt
I Never use rubbing materials, papers, microfibre cloths
II Never clean dry
III Always start to clean water soluble dirt
a If you can see grease start with solvents
IV All solvents for cleaning should be absolutely clean
a PA solvents (ultra pure)
b Destilled or demineralized water
c No ammonium containing glass cleaner like Sidolin,
Sparkle, etc.
V All tools should be absolutely clean
a Use certified wound cotton sticks and dental cotton pads to avoid lint (no Q-tips or similar!)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
No recommendation using microfiber cloths. Do note the direction of cleaning device, it is circular, not up-down-across and the types of solvents used for cleaning. In a chem-science lab environment, high purity solvents and water is readily available.
Bernice
The major reason some folks eschew microfiber cloth is the propensity for some folks to not heed the CLEAN part of the recommended usage advise. But in general, outside of the scientific world they are highly recommended.
And, honestly... how much effect do microscopic scratches have on normal photographic applications???
