Bests & Worsts Reviews from Amazon

Though the bottles look similar and both have the familiar Zeiss logo, this is not the cleaner I was looking for. I have been using the ammonia-free formula that is labeled: "Especially formulated for Carl Zeiss Optical, Inc. by NanoFILM LTD, Cleveland Ohio" that specifically states that it is safe for coated lenses. That product smells like the isopropanol that it contains. This product is labeled "Made in China" and smells like detergent. It does clean coated eyeglasses but leaves a slight film. It works well on cell phones and touch screens. I will NOT be trying it on telescope and camera lenses. Draw your own conclusion - this product has the Zeiss logo but, oddly, not the company name.
