How To Get A Smear Off A Tv Anyone Have Any Ideas On How To Get Sticky Gum Off A Plasma Tv Screen?

Anyone have any ideas on how to get sticky gum off a plasma tv screen? - how to get a smear off a tv

My son rubbed the paste all over the screen of plasma TVs. So far I've tried to ice in a bag and its application to the gums. I can get the larger pieces, but only a small spot on the screen. Any idea of help is appreciated.
