How to Clean a Monitor or Laptop Screen Without Damaging It

Most screen damage from cleaning comes from two things: the wrong liquid and too much pressure. Modern monitors and laptop screens have thin anti-glare and anti-reflective coatings that can be stripped by household cleaners. The good news is that the safe method is also the simplest.

What You Need

• Two clean, dry microfiber cloths (the kind sold for glasses or cameras)
• A little distilled water if there are stubborn marks (tap water can leave mineral spots)
• Optional: a screen-safe cleaning spray that says it is free of alcohol and ammonia

What Not to Use

• Paper towels, tissues or kitchen roll. They feel soft but contain wood fibers that leave fine scratches.
• Glass cleaner such as Windex, or anything with ammonia. It can damage anti-glare coatings and leave a cloudy look.
• Strong alcohol or acetone. These can strip coatings, especially on matte monitors.
• Spraying anything directly onto the screen. Liquid can run down into the bezel and damage the electronics.
• Dish soap. It is hard to remove fully and leaves streaks.

Some manufacturers do allow specific products on some screens, such as certain alcohol wipes on glossy laptop displays. If you want to use anything stronger than water, check your manufacturer’s cleaning guide for your exact model first.

How to Clean the Screen, Step by Step

1. Turn the screen off and unplug it. A black screen shows smudges well, and it’s safer to clean a cool, powered-off display.
2. Dust first. Wipe gently with a dry microfiber cloth in one direction, from top to bottom. This removes dust that could scratch the screen when you scrub.
3. Dampen, don’t soak. For fingerprints or spots, lightly dampen a corner of the second cloth with distilled water. It should feel barely damp, not wet.
4. Wipe with light pressure. Use small, gentle movements over the marks. Don’t press hard. If you can see the image ripple under your finger, you’re pressing too hard.
5. Dry it. Go over the screen with the dry cloth to remove any moisture and streaks.
6. Check your work. Turn the screen back on and open a full white screen. Smudges and streaks are much easier to see on white. Then check a black screen for dust and lint.

Cleaning Different Types of Screens

Matte monitors

Matte screens have a textured anti-glare coating that is easy to damage. Stick to a dry cloth and, if needed, a little distilled water. Avoid any cleaner unless the manufacturer approves it.

Glossy laptop screens and MacBooks

Glossy glass is tougher, but the same rules apply. Keyboard marks on laptop screens come from the keys touching the display when the lid is closed. A damp microfiber cloth usually removes them. Don’t close the lid with a cloth inside, as it can press on the screen.

Phones and tablets

Most phones have an oil-repelling coating. Turn the phone off, wipe with a slightly damp microfiber cloth and keep moisture away from openings.

TVs

Large TVs are easy to flex. Support the frame with one hand while you wipe with the other, and use only light pressure. On OLED TVs, use only a dry cloth unless your TV’s manual says otherwise.

How Often Should You Clean?

A quick dry wipe once a week is enough for most screens. Do a damp clean only when you can see fingerprints or spots. Cleaning too often with liquid wears coatings faster than dust does.

Spots That Won’t Wipe Off

If a mark stays after cleaning, look at it on a white and black screen:

• A sharp dot that stays the same color may be a stuck or dead pixel.
• A spot that changes when you press gently may be pressure damage inside the panel.
• A worn, shiny or cloudy patch may mean the coating is already damaged. This can’t be repaired by cleaning.

Quick Answers

Can I use eyeglass cleaner on my screen?

Many eyeglass sprays contain alcohol. Use one only if it says it’s safe for screens or coated lenses, spray it on the cloth, never the screen, and test on a corner first.

Is it safe to clean a screen while it’s on?

A dry dusting is fine, but turn it off before using any moisture. It’s also much easier to see smudges on a black, powered-off screen.
