LCD screens are commonly made of thin plastic that requires careful treatment. The wrong cleaning tools and products can cause dead pixels, leaving permanent black spots on your screen. Though many TV manufacturers recommend purchasing specialised cleaners, you can make your own with a few common household items. Remove marks, smudges and dust with a safe, homemade cleaner that's just as effective as the store-bought kind.

Things you need
- Spray bottle
- Isopropyl alcohol
- Distilled water
- Microfiber cloths
Mix one part isopropyl alcohol to three parts distilled water in a spray bottle. Shake well to mix the ingredients.
Spray a clean microfiber cloth with the screen cleaner. Spraying the cloth first prevents over-saturating the TV with liquid.
Turn off the TV and let it cool. Wipe the LCD screen thoroughly with the microfiber cloth, applying light pressure to remove any fingerprints or stains. Wrap the cloth around your finger to clean the corners and edges.
Spray a new cloth with the screen cleaner. Wipe the entire screen once again to remove any leftover dirt or streaks.
Tips and warnings
- Wait until the TV screen is cool before cleaning. This will prevent the cleaner from drying too fast, potentially leaving streaks.
- Wipe the screen with gentle pressure. Pushing too hard can cause dead pixels, permanently ruining the screen.
- Never use ammonia-based window cleaners on LCD screens. Doing so can cause the screen to turn yellow.
- Use distilled water instead of tap to prevent water spots and build-up.
