From what I've heard, Windex is not a good cleaner for camera lenses, eyeglasses, and many other surfaces.
There are several types of Windex (and other glass cleaners)...
I am not certain, but I think it is the cleaners with
ammonia that shouldn't be used on cameras, lenses, eyeglasses, etc.
At any rate, I simply don't use any Windex. I use a lens cleaning solution (or a sensor cleaning solution... essentially the same thing).
My process for cleaning lenses:
1. Remove any dust or grit with a blower, gentle brush, minivac or gentle use of a micro fiber cloth. Dust particles can be minerals that might scratch the coatings on the lens.
2. Wet clean with lens/sensor solution... just a few drops on a Pecs Pad or the corner of a clean microfiber cloth. I currently have a small spray bottle of Zeiss lens cleaning solution and spray one or two shots of that onto the cleaning pad. (Never spray directly onto the lens... too much moisture there can get "wicked" inside the lens around the perimeter of the elements, where it might do damage or take forever to dry.) Single use, pre-moistened wipes like Zeiss are fine too, but are more expensive.
3. Let it air dry or use a clean, dry microfiber cloth to dry it.
4. Polish with a Lens Pen. The wet cleaning often leaves a little "haze". This polishing removes that and makes it less likely that dust, etc. will adhere to the surface in the future.
Microfiber cloths can be cleaned and reused. Just put them in the laundry. HOWEVER, never use "fabric softener" with them in either the washer or the dryer. It will leave behind a residue that causes smearing when cleaning optics.
Pec Pads are available inexpensively in bulk. I also make my own sensor swabs with them, wrapping them around a reusable "wand".
Microfiber cloths are available in bulk, too. They seem to cost less
any place other than a camera store!
Auto parts stores have larger "terry cloth" style microfiber cloths sold in relatively inexpensive bundles and great for all types of external camera cleaning. I keep one or two in my camera bag all the time.
