How to Fix a Scratch on an LCD Screen

Look closely at the LCD screens on your electronic devices. You will notice that only a layer of plastic separates your fingers or stylus from the screen's inner components. This plastic coating is susceptible to scratches and gouges resulting from everyday use. But a mild-to-moderate scratch may be fixable by using household items like petroleum jelly and a cotton swab.

Instructions

Difficulty: Easy

Things You’ll Need:

• Cotton swab
• Petroleum jelly
• One or two soft cloths

1. Clean the surface of the LCD screen with a barely damp cloth.
2. Dry the screen with a soft, clean cloth.
3. Rub a generous amount of petroleum jelly into the scratch using a cotton swab. The petroleum jelly should fill in the scratch and remain there.
4. Immediately wipe the excess petroleum jelly off of the screen with a soft cloth being careful to leave some petroleum jelly inside the scratch to act as a patch or filler.

Tips & Warnings

• This scratch repair method is effective because of optical density. The optical density of petroleum jelly matches the plastic, LCD screen coating more closely than that of air.
• To avoid future scratches or gouges, you might consider purchasing a LCD screen protector. These screen protectors are generally made of a thin, plastic film and affix to the screen without adhesives. Not only can they protect against scratches, but they also keep the screen free of dirt, oil and dust while simultaneously reducing glare.
• When wiping the screen as described Step 4, avoid pressing too hard or you will inadvertently remove the petroleum jelly from inside the scratch.
• Using petroleum jelly to fill a scratch on your LCD screen could void your screen's warranty. If you are concerned about warranty issues, consult your user's manual for more information.
