Go to the cleaning section at Walmart ( where they have the brooms , mops and cleaning brushes) they sell different kind of microfiber cloths there, grab the blue one specific for LCD screens ( you will notice the difference in texture). That what I use on everything glass related. Screens , glasses, LCD... This is the best microfiber cloth for glass products ever. It cost like $2.
Don't go to the electronics section and grab the fancy wet wipes or anything from there, it will just be overpriced junk. I would post a pic , but I threw away the packaging...
