If your TV is an CTR (one of those heavy lumpy things) you can use any window cleaner. For an LCD, clean the screen with a soft cloth and warm water to get most of the dirt/(smoke) off.
When dry, mix an even solution of isopropyl alcohol and clean water in a spray bottle and spray and wipe the screen lightly, this will get rid of those streaky marks.
Get Isopropyl alcohol from the chemist, one bottle will last you for years.
Not too sure about using cleaner fluid, there is a plastic cover over the LCD screen to stop anti-glare.
