How to Clean a Laptop Screen Safely (Without Streaks or Damage)

The safe method, in short: Shut the laptop down and unplug it. Wipe the screen with a dry microfiber cloth to lift dust. If smudges remain, lightly dampen a second microfiber cloth with distilled water — damp, never dripping — and wipe gently. Finish by buffing with the dry cloth. Never spray any liquid directly onto the screen.

That method is safe on virtually every laptop, because every major manufacturer allows a water-dampened soft cloth. Stronger cleaners, including alcohol, are a different story: what’s allowed depends on who made your laptop and what coating its screen has. We cover exactly what each manufacturer says further down.

What you need

• Two soft microfiber cloths — one for damp wiping, one kept dry for dusting and buffing. Clean, with no grit trapped in them.
• Distilled water — tap water carries dissolved minerals that can dry into spots and a faint film. Distilled (or deionized) water evaporates clean, which is a big part of a streak-free finish. Lenovo’s own instructions specify distilled or deionized water when mixing a cleaning solution.
• Optional: a screen-safe cleaner — a cleaner made for LCD or display screens, alcohol- and ammonia-free unless your manufacturer allows alcohol (see the brand table below).

That’s genuinely it. You don’t need a kit, compressed air, or special sprays for the screen itself.

How to clean a laptop screen, step by step

1. Power off, unplug, and let it cool

Shut the laptop down completely — not sleep — and unplug the charger and any accessories. Apple, Dell, and Lenovo all say to turn the computer off and disconnect power before cleaning, and Microsoft says to unplug your Surface first. A dark screen also makes every smudge and speck of dust easy to see, and a cool panel won’t flash-dry your cleaning water into streaks.

Tip: tilt the screen toward a window or lamp so light rakes across it. Smudges you can’t see head-on will show up.

2. Dust it dry first

Take the dry microfiber cloth and wipe the whole screen with very light pressure. This removes the dust and grit that would otherwise get dragged across the surface when you add moisture — which is how fine scratches happen.

For many screens, this step alone is enough. Don’t go to liquid unless you need it.

3. Damp-wipe the smudges

Lightly dampen a corner of the second cloth with distilled water. It should feel barely damp — if you can squeeze out a drop, it’s too wet. Dell’s guidance puts it as damp, not dripping.

Wipe with gentle, overlapping strokes — small circles or an S-shaped pattern work well. Dell specifically recommends wiping display screens in one direction, top to bottom, which is a good habit on any laptop because it pushes moisture away from the hinge area rather than into it.

How hard should you press? Barely at all. Let the cloth do the work. LCD panels are pressure-sensitive, and Apple, Dell, and Microsoft all warn against excessive wiping or rubbing hard. Microsoft notes that the Surface touchscreen is coated to make it easier to clean, so you don’t need to rub hard.

4. Buff it dry

Immediately follow with the dry cloth, using light strokes, to pick up any remaining moisture. This is the step that prevents streaks. Let the screen air-dry fully before closing the lid or powering on — Lenovo says to let the display dry before closing the lid, and Dell says not to turn your computer on if any moisture is visible.

5. Don’t forget the edges

• The bezel: dust and skin oil collect where the glass meets the frame. Run the damp cloth along the edge, but keep it barely damp here — the seam is exactly where liquid can wick inside.
• The strip above the keyboard (and the screen’s bottom edge): when you close the lid, the keys touch the screen and transfer finger oil. That’s why you often see faint keyboard-shaped marks. Give this area the same gentle damp wipe.

What not to use on a laptop screen (and why)

Can you use Windex on a laptop screen?

No. Window cleaners are on the do-not-use list for Apple displays, and Microsoft says never to use glass cleaner on a Surface screen. Dell is the one exception worth noting: it says a glass cleaner designed for display surfaces can be used, but recommends avoiding products containing ammonia. A standard household window spray isn’t that.

Can you use alcohol on a laptop screen? It depends on the maker

This is where most guides get it wrong, in both directions. Some say alcohol is fine for every screen; others say it will ruin any screen. Neither is accurate. Whether isopropyl alcohol (IPA) is approved depends on your laptop’s manufacturer and screen coating, and the major brands don’t all say the same thing.

What Apple actually says: for a MacBook, MacBook Air, or MacBook Pro screen, Apple’s first instruction is to dampen a soft, lint-free cloth with water only. For hard-to-remove smudges or fingerprints, Apple says you can use a cloth moistened with a 70-percent isopropyl alcohol solution to gently wipe the display. Separately, Apple’s disinfecting guidance says 70 percent isopropyl alcohol wipes, 75 percent ethyl alcohol wipes, or Clorox Disinfecting Wipes may be used gently on hard, nonporous surfaces including the display — but not products with bleach or hydrogen peroxide.

Other manufacturers set different limits. Here’s what each one’s own support guidance supports:

Where they disagree:

• Strength: Lenovo’s screen mix is 50-50 IPA and water, while Dell, HP, Apple, and Surface reference 70% (Surface says 70% or less).
• Ethyl alcohol: Apple permits 75% ethyl alcohol wipes; Lenovo lists ethyl alcohol as something not to use.
• Disinfecting wipes: Apple permits Clorox Disinfecting Wipes on the display; Microsoft says not to use disinfectant wipes on any Surface touchscreen.
• Glass cleaner: Dell allows an ammonia-free cleaner made for displays; Microsoft says never use glass cleaner.

The practical rule: start with distilled water every time. Only step up to alcohol if water doesn’t remove the mark, and only at the strength your laptop’s manufacturer approves. If your brand isn’t listed — or you own a model with a special anti-glare or matte finish — look up your exact model’s user guide or support page before using anything stronger than water. When in doubt, water and patience are the safe choice.

Stubborn cases and special screens

Greasy fingerprints that smear instead of lifting

Skin oil spreads before it lifts. Don’t press harder — do a second (or third) pass with a freshly dampened section of the cloth, then buff dry. Rotate to a clean area of the cloth each pass so you’re not just moving the oil around. If water still won’t shift it after a few passes, that’s the point to consider an alcohol solution — only if your manufacturer allows it (see the table).

Sticky residue (food, stickers, tape)

Hold a damp corner of the cloth against the spot for a few seconds to soften it, then wipe gently. Repeat rather than rubbing hard. Never scrape with a fingernail, a blade, or the edge of a card. If residue won’t budge, use only the stronger cleaner your manufacturer approves, applied to the cloth.

Matte vs. glossy screens

• Glossy screens show every smudge but usually wipe clean easily. Streaks are the main enemy — which is why the dry buff matters.
• Matte (anti-glare) screens hide reflections with a textured or coated surface. Oil can sit in that texture, so they may need a couple of gentle passes. Be especially gentle here: anti-glare coatings are the ones most easily marked by harsh chemicals or heavy rubbing.

Touchscreen laptops

Touchscreens collect far more fingerprints, so they need cleaning more often — but the method is the same. Power off first so you don’t trigger random taps. On a Microsoft Surface, use a screen-cleaning wipe or a soft, dry, lint-free cloth, dampened with water or a 70%-or-less IPA solution only when necessary, and skip disinfectant wipes on the touchscreen. Microsoft also advises keeping the device out of prolonged direct sunlight, since UV light and heat can damage the display.

MacBook screens and anti-reflective coating

MacBook displays have an anti-reflective coating, so go gentle and go water-first. Follow Apple’s order: water-only damp cloth, and a 70-percent IPA solution on the cloth only for hard-to-remove smudges. Avoid excessive wiping, which Apple warns can cause damage.

If your MacBook Pro has a nano-texture display, Apple has separate instructions: use only the polishing cloth that came with your Mac. For infrequent cleaning of hard-to-remove smudges, Apple says you can moisten that cloth with a 70-percent IPA solution. If you’ve lost the cloth, Apple sells a replacement polishing cloth.

"Cleaning made my screen look worse" — how to fix it

Streaks and a hazy film almost always mean too much liquid or a dirty cloth. The fix:

1. Let the screen dry fully.
2. Buff it with a clean, completely dry microfiber cloth using light, overlapping strokes.
3. If haze remains, do one more pass with a cloth that’s barely damp with distilled water — wrung out much more than last time — then buff dry immediately.
4. Wash your cloths. Microfiber holds oil and old cleaner residue, which gets smeared right back onto the screen.

If you used tap water, switching to distilled water usually ends the "dried spots" problem.

Cleaning the rest of the laptop (quick version)

The screen is the priority, but while the laptop is off:

• Keyboard: tilt the laptop and loosen crumbs with short bursts of compressed air (Dell and Lenovo both mention compressed air for this). Then wipe the keytops with a barely damp cloth — Lenovo, Dell, and HP allow isopropyl alcohol on the cloth for keys; keep liquid from dripping between them.
• Exterior and palm rest: a damp, lint-free cloth. Apple says to avoid aerosol sprays, solvents, abrasives, and hydrogen peroxide cleaners on a MacBook’s finish; Lenovo warns that bleach, acetone, and ammonia-based cleaners can cause paint peeling.
• Vents: dust-clogged vents make laptops run hot and loud. Lenovo recommends clearing vents with compressed air while the PC is off. If heat is your real problem, see our guide to laptop overheating.

How often should you clean a laptop screen?

• Dry dust: about once a week, or whenever you notice dust.
• Damp wipe: whenever smudges or fingerprints are visible — for most people, every week or two; touchscreens may need it more often.
• Alcohol solution: only for marks water won’t remove, and only if your manufacturer approves it. It’s not an every-day cleaner.

Keep it cleaner for longer

• Close the lid when you’re not using the laptop. Microsoft recommends keeping your Surface covered when you’re not using it — it’s good advice for any laptop.
• Don’t touch the screen (non-touch models) — point, don’t poke.
• Wash your hands before long sessions; skin oil is the main source of smudges.
• Keep the keyboard clean so fewer oils transfer to the screen when the lid closes. Dell’s blog suggests laying a thin microfiber cloth over the keyboard before closing the lid.

FAQ

What is the best thing to clean a laptop screen with?

A clean microfiber cloth, dry first, then lightly dampened with distilled water. It’s safe across all major brands and removes most dust and fingerprints. Stronger cleaners are only for marks that water won’t remove, and only at the strength your manufacturer approves.

How do I clean my laptop screen without streaks?

Use distilled water instead of tap water, keep the cloth damp rather than wet, wipe with light pressure, and buff dry right away with a second dry cloth. Streaks are usually caused by too much liquid, a dirty cloth, or cleaning a warm screen.

Can I use rubbing alcohol on my laptop screen?

It depends on your laptop. Apple, Dell, HP, and Microsoft Surface each allow an isopropyl alcohol solution at specific strengths (around 70% or less), Lenovo specifies a 50-50 mix with distilled water, and every one says to apply it to a cloth, never directly to the screen. Check your model’s guidance first, and always try water before alcohol.

Can I use Windex on my laptop screen?

No. Apple and Microsoft both say not to use window or glass cleaners on their screens, and Dell recommends avoiding glass cleaners containing ammonia. Household window sprays can damage anti-glare and anti-reflective coatings.

Are disinfecting wipes safe for laptop screens?

Not universally. Apple says 70% isopropyl alcohol wipes, 75% ethyl alcohol wipes, or Clorox Disinfecting Wipes can be used gently on its displays. Microsoft says not to use disinfectant wipes on any Surface touchscreen. No major brand allows bleach-based wipes on its screens.

How do I clean a MacBook screen?

Shut it down, unplug it, and wipe the screen with a soft, lint-free cloth dampened with water only. For hard-to-remove smudges, Apple allows a cloth moistened with a 70-percent isopropyl alcohol solution. If your MacBook Pro has a nano-texture display, use only the polishing cloth that came with it.

Can I use vinegar to clean my laptop screen?

Lenovo’s consumer FAQ pages mention distilled water mixed with white vinegar, but Lenovo’s own support instructions list water or a 50-50 isopropyl alcohol and distilled-water mix instead, and the other major manufacturers don’t list vinegar. Distilled water alone is the safer default.

Is it OK to use a paper towel or tissue in a pinch?

Better not. Apple specifically says to avoid paper towels, and paper products can leave lint and fine scratches on screen coatings. If you don’t have microfiber, a soft, clean, lint-free cotton cloth (like an eyeglass cloth) is a better stand-in.

The bottom line

Power off, dust dry, wipe with a barely damp microfiber cloth and distilled water, then buff dry. That handles nearly every smudge on any laptop. Reserve alcohol for stubborn marks — and only after checking what your laptop’s manufacturer actually allows, because Apple, Dell, HP, Lenovo, and Microsoft draw the line in different places.
