Annoying streaks can ruin an LCD TV screen.

LCD TV screens have a plastic film over them that allows the liquid crystals in the display to show the picture at optimal quality. These screens are delicate and cannot be cleaned like regular glass. One problem that often causes streaks to appear is if you clean the screen with an ammonia-based product, such as window cleaner. These streaks can be removed, usually with proper cleaning methods or with a solution of isopropyl alcohol.


Step 1

Turn off the TV. Spray the screen with compressed air to remove large dust particles without damaging the screen or causing scratches on the surface.

Step 2

Spray the screen with a detergent gel cleaner designed for LCD screens. Allow the solution to sit for about 30 seconds.


Step 3

Wipe the gel away with an anti-static cleaning cloth or a microfiber cloth. Use circular motions to gently wipe the surface of the screen. Do not apply too much pressure or you might damage the display. Allow the screen to dry.

Step 4

Create a mixture of half isopropyl alcohol and half clean water. Dip a microfiber cloth into this mixture and wring out the cloth so that it is damp but not dripping.



Step 5

Rub the cloth lightly over the streaks on the screen to remove them. If the 50-50 concentration does not remove the streaks, rub the streaks with 100 percent isopropyl alcohol to remove them from the screen. This method should remove most streaks from the surface of the LCD screen.

Step 6

Clean the screen with the gel cleaner once more to remove any alcohol residue from the surface of the LCD screen. It is not a good idea to leave isopropyl alcohol residue on the screen for extended periods as this can damage the screen.
