Nerdwax Magic Drops

Works super well, highly recommend

ETA: After experimenting with Magic Drops on different surfaces (glasses, phone screen, computer screens, different glasses), I have found that a drop is too much for all of my glasses except one huge pair I have. If you're finding your glasses smeary after using these, try using less than a drop - I have to tap a teeny tiny little bit onto the lens or put a drop on my finger and distribute it over both sides of the lenses. A full drop is enough to clean my entire phone screen. Once I figured this out, the drops became pretty amazing.

>Original critique: I found myself wishing that the instructions were more thorough. I know it sounds silly, glasses cleaner should not be very complex. I see that in a lot of negative reviews, people are directed to an "application tips section," but I cannot for the life of me find such a thing for any product other than the wax stick.

It feels and cleans amazing
