Vinegar works well as a cleaning solution for led and LCD flat screen Televisions as well as Computer Monitors.
Take a spray bottle and mix equal parts Vinegar and Equal parts Water into the spray bottle.
Then spray the Vinegar and Water cleaning solution onto a microfiber cloth and then wipe the LED flat screen TV or LED Computer monitor gently with the microfiber cloth.
Just don't press down to hard on the screen because you could damage the LED Screen by pressing too hard.
Just wipe the screen down gently and repeat the process if needed.
