Asking how to clean lenses is as bad as asking how to clean a barrel. As others have said best to use an air blower to get all the debris out first before using anything to wipe on a lens. I like the idea of lens wipes only because you know they are clean starting out. Microfiber cloths are great, but as soon as you use one, you have no idea what it has on it. The best option is to use a shade etc. to try and keep anything but dust off the lens, since that's easily blown away. Much like a barrel, more damage is probably done to optics from overcleaning than undercleaning. There's not only the worry of grinding something abrasive into the lens and scratching it, but also the concern of both a particular cleaner thinning the coating and if applied heavily hurting the seals.
Also while it's easy to be OCD, having been a photo person for decades, you'd be amazed how much crap you can have on a lens and not be able to see it in the image. In a scope a smudge on the front has less impact than the rear. You can put your finger right in front of a camera lens and you won't see it in the photo, mostly you'll notice reduced brightness, and some extra flare if whatever is on the lens gets direct sunlight on it.
Canned air is bad because many of them can easily end up spurting the propellant and other crap even when held upright in very small amounts, esp now that canned air contains bitterant. Better to just use a bulb type blower.
My process is usually bulb blower, brush, and only as a last resort will I wipe a lens.
Some manufacturer recos taken from their manuals (Interesting that Leica specifically recommends not using pre-moistened chemical lens cleaning cloths) and not one of them recommend any kind of lens cleaner fluid.
Zeiss spotter:
Do not wipe off coarse dirt particles (e.g. sand) from the lenses, rather blow them away or use a fine brush to remove them. Fingerprints can affect the surfaces after a while. The easiest way to clean optical surfaces is to breath on them and rub them softly with a clean lens cleaning cloth.
Swarovski spotter:
When cleaning the lenses, first remove larger particles with an optical lens brush. For the subsequent thorough cleaning we recommend breathing onto the lens surface to form a coat of condensation and then cleaning it with a soft, moist cloth.
Leica spotter:
Coarse dirt particles, as for example sand, should be removed with a fine hair brush, or be blown away. Finger prints and such, on the front lens and eyepiece lenses can be cleaned with a damp cloth and wiped off with a soft, clean leather or dustfree cloth. The special cleaning cloths used for eye glasses are not recommendable. They are impregnated with chemicals that can damage the optical glass (the glass used for eyeglasses has a different composition than that used for spotting scopes). Alcohol and other chemicals musn't be used for cleaning the housing. If necessary, wipe with a soft, dry cloth. For excessive soiling the Televid can be cleaned by simply rinsing under running water.
I've used the zeiss clothes for sunglasses and eyeglasses, they're handy to have in the truck/pack but I've never been that impressed with them and I'd never use them on any of my optics.
