How to Remove Streaks From 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.

Annoying streaks can ruin an LCD TV screen.

Step

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

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

Step

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

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

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

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.
