I found that certain brands of paper towel leave streaks. The best in my opinion is Bounty. Stay away from Viva (I think it's "treated").
Fold one sheet to about the size of the screen and get the towel wet with many drops of the recommended Windex and wipe sideways once. I let the screen "air dry". Don't use a dry sheet, it leaves a film. I just wipe across with the very wet towel and let it dry by itself. I only takes a second or two. Just my opinion. Others, please join in.
Thanks.
