To clean a laptop screen safely, first shut the laptop down and unplug it, then wipe the screen gently with a clean, dry microfiber cloth. For fingerprints and smudges that don’t lift, dampen the cloth — not the screen — with distilled water, or a 50/50 mix of distilled water and isopropyl alcohol for a matte, non-glossy display. Never reach for paper towels, tissues, ammonia, or glass cleaners like Windex: those strip the delicate anti-glare and fingerprint-resistant coatings and can leave permanent cloudy marks or scratches.

What you’ll need

  • A clean, soft microfiber cloth (the kind sold for eyeglasses or camera lenses).
  • Distilled water — not tap water, which leaves mineral spots.
  • Optionally, 70% isopropyl alcohol for a stronger 50/50 solution on non-glossy screens.
  • A small spray bottle, only if you’ll mist the cloth (never the screen).

Skip anything paper, anything abrasive, and any household cleaner containing ammonia, acetone, or bleach.

Step-by-step

  1. Power off and unplug the laptop. A dark screen makes every smudge visible, and powering down removes any electrical risk.
  2. Dry-wipe first. Using the microfiber cloth, gently wipe the screen to lift dust and loose fingerprints. Work in one direction or small circles, with light pressure — never press hard.
  3. Dampen the cloth for stubborn spots. Lightly moisten a corner of the microfiber with distilled water (or the 50/50 solution on a matte screen). It should be barely damp, not wet.
  4. Wipe gently again over the marks, then go over the area with a dry part of the cloth to remove any moisture.
  5. Let it dry fully before closing the lid or turning the laptop back on — a minute or two is plenty.

The rules that protect your screen

A few habits prevent the most common — and permanent — damage:

  • Never spray liquid directly on the screen. Droplets run to the edges and seep into the bezel and electronics. Always apply to the cloth.
  • Never use paper towels or tissues. They’re made from wood fibers that leave micro-scratches and shed lint.
  • Avoid ammonia and glass cleaners. Windex and similar products dissolve the coatings that reduce glare and repel fingerprints.
  • Don’t scrub. Pressing hard on an LCD or OLED panel can cause discoloration or dead pixels. Let the solution do the work.

Glossy vs. matte (anti-glare) screens

The type of display changes what liquid is safe:

  • Glossy screens (most MacBooks and many consumer laptops): distilled water on a microfiber cloth is the safest bet. If you use alcohol, keep it light and check your manufacturer’s guidance first.
  • Matte / anti-glare screens: a 50/50 distilled-water-and-isopropyl-alcohol mix cuts through oils well, but the textured coating is easy to wear down, so wipe gently and infrequently.

When in doubt, plain distilled water handles the vast majority of everyday smudges on either type.

Cleaning the keyboard and case while you’re at it

Since the laptop is already off, tidy the rest:

  1. Turn the laptop upside down and give it a gentle shake, or use a can of compressed air in short bursts to clear crumbs from the keyboard.
  2. Wipe the keys and palm rest with a slightly damp microfiber cloth or a 70% isopropyl wipe — these areas tolerate more than the screen does.
  3. Avoid getting moisture into ports, vents, or the gap around the keys.

Cleaning a touchscreen or 2-in-1

Touchscreen laptops and 2-in-1s pick up more fingerprints because you tap the display directly, but the method is the same — the glass still carries an oleophobic (oil-repelling) coating you don’t want to scrub away. Use a dry microfiber cloth for daily fingerprints and a barely damp cloth with distilled water for stubborn ones. Avoid alcohol on glossy touch panels unless the maker specifically allows it, since repeated use can dull the fingerprint-resistant layer that keeps swiping smooth.

Spotting smudges you’d otherwise miss

Turning the laptop off doesn’t just reduce risk — it makes cleaning far more effective. Against a black screen, every fingerprint and streak stands out, so you can tell whether you’ve actually lifted a mark or just moved it around. Tilt the screen toward a light source and check from an angle; residue and streaks show up that vanish when you look head-on. Finish by buffing any leftover streaks with a dry section of the cloth.

Existing scratches or worn coating

If the anti-glare finish already looks patchy or hazy — often the result of earlier cleaning with the wrong products — there’s unfortunately no way to restore it; the coating is worn, not dirty. A matte screen protector can mask the unevenness and prevent further wear. Light surface scratches can’t be safely buffed out at home, and “scratch repair” pastes risk doing more harm than good on a coated display, so it’s best to leave them alone.

How often to clean

A quick dry wipe whenever fingerprints bother you is fine, and a slightly damp clean every week or two keeps a screen clear without over-handling the coating. The gentler and less frequently you use liquid, the longer that anti-glare finish lasts. Once your laptop is spotless, it’s a good moment to sort out the rest of your devices too — our guides on freeing up space on iPhone and resetting iPhone network settings cover two more common housekeeping jobs.
