I always use vinegar and some water with a microfiber cloth to clean my LED TV and LED computer monitors.
I use a spray bottle and mix half with vinegar and half with water and then shake the vinegar and water mixture to mix them up.
Then I spray the microfiber cloth with the vinegar and water and then wipe the LED TV or LED computer monitor down gently.
I've never had a problem with any streaks or anything using vinegar and water to clean the LED screens.
If you use a regular rag or paper towel you might get particles from the paper towels or lint from a wash cloth on the screen.
But if you use a microfiber cloth then there won't be any particles or lint left on the LED TV or LED monitor.
