Cleaning LCD

After looking at the screen on my flat panel i noticed a line about 1" not really a scratch but more like a rub mark. I bought some isopropyl
alcohol and used a cotton ball but the mark is still there and while the alcohol dries super fast it kinda leaves streaks. Does anyone know what else can be used? No sandpaper suggestions please. :lol:

Nevermind. Decided to return it.

Well at least i was right about the type of alcohol to use. :thumb:
