Hi there happy to help.
Can you give me the model number of the TV?
Sorry, I am not near my TV.
Is it Plasma or LCD?
OK, here is what I suggest.......
Buy this kit.......
It includes the solution and proper fabric patches to use to safely clean your screen.
There are some do it yourself home remedies out there, but I prefer you just buy this kit. If you use the wrong solution or wrong type of fabric, dirty fabric(even a single piece of dirt), you can scratch your screen. A screen scratch is PERMENANT and it is cheaper to replace the TV than to replace your screen.
Spend the 12 dollars and do it right. The above kit is the best on the market.
Hope this helps,
