How To Clean LCD TV
The first thing to check is your TV manual for cleaning instructions. Look for any warnings that might indicate what types of cleaning products or chemicals to avoid. It's best to avoid commercial cleaners, especially ones that have alcohol or ammonia, like window cleaners.
Older tube TVs, which have a glass screen, could tolerate these types of cleaners but LCD and plasma screens could be easily damaged by such harsh cleaners. It's also not a good idea to use a vacuum brush as this could cause scratches on your LCD TV.
It's best to use a damp soft cloth, like a microfiber cloth, as using paper towels or other wood base products could easily scratch the screen. Make sure the cloth is just damp and not dripping wet as drips could get inside the screen. Also if you have an LCD TV make sure not to press to hard on the screen as your cleaning as this could damage the screen.
