Know Before You Clean...
If you think that your flat screen LCD TV can be cleaned by a window cleaning solution, you can't be farther than the truth. The point here is that the panel is not similar to the older models we used to have. Those television sets were made of thick glass which could easily be cleaned with a window cleaner and a paper towel.
Of course, this method did remove all the dirt and fingerprints off the screen. However, if you make the mistake of following the same cleaning method now, you'll just end up making a huge error.
The protective layer on your TV needs special care and cleaning them with harsh chemicals (which includes ammonia, glycerin, alcohol, etc.) can be disastrous. Also, just wiping them with kitchen or paper towels should be avoided. Sometimes, you can end up scratching the delicate surface or leave lint on the surface.
Best Possible Technique
It could be possible that you got scared about keeping your television panel away from chemicals. Well, the point here was to keep you alert and tell you what you shouldn't do. So to summarize, no chemical cleaners, no liquid spray cleaners, and no paper towels, newspapers, or magazines.
When you want to clean flat screen LCD TV, you can either search for a commercial cleaner which specifically says that it is safe for laptop, LCD, and plasma screens. Only then, you should use the cleaner with a soft, cotton towel for cleaning. But there is another method to clean the TV.
Follow the tips and instructions mentioned here, and you'll be left with a clean, unharmed screen.
