How to Properly Clean Your Laptop Screen Without Damaging It
It all started when I was editing an article one afternoon. Out of nowhere, I noticed a strange little accent mark hovering above the letter “a.” I tried deleting it—backspace, backspace, backspace—but it wouldn’t go away. My first thought? Maybe my keyboard had accidentally switched to Spanish mode. But no, that wasn’t it. After squinting closer, I realized the culprit wasn’t my software at all—it was a tiny fleck of dust clinging stubbornly to the screen. That’s when I knew: my laptop was overdue for a deep clean.
Cleaning your laptop screen might seem simple, but as with most valuable tech devices, there’s a right and wrong way to do it. One wrong move, and you could end up scratching your display or leaving behind streaks that make your screen look worse than before. So, here’s a detailed, foolproof guide on how to clean your laptop screen properly—so you’re left with a crystal-clear, like-new finish.
The right (and wrong) way to clean your screen
First things first: resist the urge to use your sweatshirt sleeve or a paper towel to wipe away smudges. Trust me, we’ve all done it, and it’s one of the easiest ways to cause micro-scratches or leave lint on your screen. “I always use a microfiber cloth with a small amount of a very gentle chemical that specifically states it is ‘LCD safe,’” says Pedro Serrano, senior technician at New York Computer Repair. “The number one step is to power off the device before you clean the screen with the cloth.”
Serrano recommends using gentle, circular motions to clean the display, being careful not to press too hard. Once done, let your screen dry completely before turning your laptop back on.
He also warns against using materials like paper towels, napkins, or tissues, which can tear apart and leave tiny fibers behind. These fibers can create even more dust build-up or, worse, small abrasions on your display. “Anything abrasive should be avoided entirely,” he adds.
What about OLED screens?
If your laptop has a newer OLED display, you’ll want to take extra precautions. These screens are more sensitive to certain chemicals and moisture levels than standard LCD or LED ones. In this case, use a clean microfiber cloth lightly dampened with a 70% ethanol solution, as recommended by MSI. The same method applies to smartphone or tablet screens with similar display technology.
Step-by-step: How to clean your laptop screen safely
1. Power down your laptop completely
Before you start cleaning, shut down your device and unplug it from any power source. Even if your cleaning solution is screen-safe, it’s best to avoid any risk of liquid touching live hardware components.
2. Use the right cleaning materials
Stick to a microfiber cloth (the kind used for glasses or camera lenses) and a screen-safe solution labeled for LCD or OLED use. Avoid glass cleaners like Windex—they often contain ammonia, which can leave permanent streaks or cause discoloration.
3. Wipe gently in small, circular motions
Spray your cleaning solution onto the cloth, never directly on the screen. Then gently wipe in circular motions until the smudges or fingerprints disappear. Don’t rush—slow, light strokes are far more effective (and safer) than hard scrubbing.
4. Let it dry completely
Allow your screen to air dry before powering your device back on. This prevents moisture from seeping into the edges or ports, where it can cause internal damage.
What not to use when cleaning your laptop screen
To keep your display safe and streak-free, avoid the following products and materials at all costs:
- Paper towels, napkins, or tissues
- Cotton shirts or regular fabric cloths
- Harsh chemicals containing ammonia or bleach
- Any soap-based solution (including dish soap)
- Window cleaners
- Makeup removers or household wipes
- Excess liquid that could drip into your keyboard or ports
Final tip: Keep your screen spotless longer
Once your screen is clean, try to make it last. Avoid touching your display unnecessarily, and close your laptop when not in use to prevent dust build-up. If you’re in a dusty workspace or often eat near your computer (we’ve all been there), consider keeping a microfiber cloth handy for quick touch-ups.
Cleaning your laptop screen the right way isn’t just about keeping it shiny—it’s also about preserving your device’s longevity and ensuring your display remains sharp, bright, and flawless for years to come.
