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?
We also give out sprays and microfiber cloths, and I always tell people to use them apart. Just because both says Zeiss doesn't mean they're to be used together
I should have clarified that they were both part of the same kit, with no other cloths provided.
Also, what I do is pretty much the same as what Zeiss says to do in their instructions, see this video link (couldn't find written instructions on their site): https://www.zeiss.com/vision-care/us/need-new-eyeglasses/eyeglass-cleaning-solutions.html#overlay-benefits-832427451
Lastly, what do you mean by using the spray and cloth apart? Do you mean using the cloth dry? Because that is even greasier than using the spray+cloth.
