Lens manufacturers say that anything other than a microfiber cloth will damage the coatings on a lens. But microfiber cloths eventually pick up crap and they look like they're a pain to wash.
How do you keep your lenses clean? Are you using cloth/kleenex or microfiber cloths? If you use microfiber cloths, how do you clean those?
I use microfiber cloths, dawn dish soap, and water for a deep clean every once in a while. The microfiber cloth kinda gets cleaned in the process. I then use a second dry microfiber cloth to dry it off and prevent water spots on the lenses. Unfortunately I have to shake out my glasses before drying since water gets stuck in between my frames and my lenses.
For quicker cleaning, I use those Zeiss glasses wipes, though not entirely sure if getting brand name is important or not.
Yeah it's pretty wasteful. I've tried the Zeiss spray+microfiber cloth, but I haven't had the greatest luck with it. I tried to use it just now to remind myself what it's like, and I find that it spreads a thin greasy residue on my lenses.
Cleaning with dish soap is only a bit more effort and is much more effective in my experience (my glasses feel brand new afterwards). The Zeiss wipes get most of the way there usually, but I sometimes need two instead of one.
Odd. I've tried the Zeiss spray+microfiber cloth before, and it just didn't work for me. It leaves greasy smudges on my lenses. I've found that only dish soap or the Zeiss disposable wipes actually left a clear and clean lens. Are you using Zeiss spray or a different lens cleaner?
