Help! Pen mark on TV Screen.

[Robbiee19]

Hey I have a RCA 52" CRT in the basement for the kids. Well, the 6 yr old put a small pen mark on the screen (blue). The pen is more like a marker. Tried water with a cloth, but no good. Any body have some suggestions!? The screen is not the tube but feel's like a plasitc screen. I will take any help on this one.:confused:

Acetone (Nail Polish Remover) should be able to get rid of the marker. I'm not quite sure about the plastic screen. It wouldn't hurt the glass tube at all and should be fine on most plastics. What brand/model of TV do you have?
