This is what I use for my WOZ invisiglass and all my games. I just mix 50% distilled water with 50% of the 90% alcohol in a spray bottle and wipe off with a microfiber cloth. It works really great, better than Windex in my opinion, no streaks or lint. It also makes a nice hand sanitizer.

Newspapers also work great, but I don't have any of them around anymore.
