L.O.
Walmart carries premoistened eyeglass wipes, and I wipe the screen with them, and use an old cloth diaper(I have loads of them from back in the day) to wipe any lint and smudges leftover from the wipes.
I've used many different types of sprays for cleaning TV and monitors, but none seem to work as well as these cheapy eyeglass wipes.
Hope this helps.
