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 a chamois cloth, seems to pick up oil/smudges even better that microfiber and need less washing. Also super easy to wash when it does need it. I basically just cut a dollar bill sized section off a natural off-brand sham-wow and it works better than anything else I’ve used
