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’ve been using Windex and Bounty. 😬 Probably not the best options, but they seem to get the job done for me.
I mention Bounty because regular paper towels are crap for that sort of thing.
