Bests & Worsts Reviews from Amazon

Ignore the negative reviews on this product! The people leaving negative reviews are either incapable of interpreting and following instructions or they simply just complain about everything. This is hands down the best glasses cleaner I have ever used in my entire life bar none... IF you follow the directions to properly clean your glasses. When it comes to facial oils, finger smudges and water spots, this stuff cleans your lenses crystal clear with no residue or streaking, and I don't know what people are saying when they say it has a chemical smell. They either have very sensitive sniffers, intentionally sniffing the contents of the bottle or are using way too much of the product to clean their glasses. I have not experienced any issues with a lingering or offensive chemical smell while using this product and it makes my $500 prescription lenses like brand new every time I use it. If your glasses have a bunch of gunk on them, including dust and gritty debris particles, then you should rinse them under running water first and maybe use a mild dish soap to remove the heavier gunk and gritty debris by lightly sweeping the lenses with your fingers under the running water. Don't spray the Koala Kleaner on the lenses and just start rubbing it with the supplied micro-fiber cloth. Fine sand, dust and other particles can be abrasive and only a fool would believe they can just rub them around on their lenses without consequence, even with the Koala Kleaner sprayed on the lenses. If you're too lazy to spend the extra few minutes properly rinsing heavier gunk and debris from your lenses or to hand wash the micro-fiber cloths or see nothing wrong with using a paper towel or your shirt for wiping, then you deserve the scratches and flecking of your coatings and lenses. It's not rocket science, it's common sense, so don't blame the product for your own ignorance. You have been educated!
