How to clean an LCD screen without streaks

Updated March 23, 2017

LCD screens are not made of glass, like older CRT monitor and television screens. Instead, they are made up of a thin layer of plastic that stretches over the liquid crystals that form images on the screen. Ammonia-based glass cleaners cause streaks on LCD screens and can damage the plastic. You can purchase commercial LCD screen cleaners, but they are costly and contain ingredients you probably already have at home. By making your own screen cleaner, you can keep your LCD screens clean and streak-free without spending a lot of money.

Mix 1 part isopropyl alcohol with 1 part water in a spray bottle. Isopropyl alcohol is also called rubbing alcohol. You can find it in your local chemist or grocery store.

Spray the isopropyl alcohol and water mixture directly onto a microfiber cloth. Spray just enough to dampen the cloth. Do not spray the screen directly.

Wipe the microfiber cloth from side to side on the screen. Do not wipe in a circular motion because that can cause dust and dirt to scratch the screen.

Wipe the screen dry immediately with a clean, dry microfiber cloth.


Do not use paper towels on your LCD screens because they can scratch the plastic coating on the screen.


Keep isopropyl alcohol away from pets and children.
