The safest way to clean your monitor
Turn off and unplug your monitor before you clean it. A powered-off screen is safer to touch, and you will see dust and smudges more clearly on a dark surface. Wait a few minutes after unplugging so the screen cools down — this also reduces the risk of static electricity damaging the electronics inside.
Use a microfiber cloth, the same kind that comes with eyeglasses or camera lenses. This is the only cloth you should use on a monitor screen. Microfiber is soft enough not to scratch the coating on modern displays, and it grabs dust without needing liquid. Wipe gently in circular motions, applying almost no pressure — let the cloth do the work.
For the plastic bezel and stand, you can use a slightly damp cloth if needed. Dampen it with distilled water only, never tap water, because minerals in tap water leave streaks and spots. Wring out the cloth so it is barely wet, not dripping. Keep all moisture away from the screen itself and away from any ports or cables on the back.
Key Takeaways
- Always turn off and unplug your monitor before cleaning, and wait a few minutes for it to cool.
- Use only a microfiber cloth on the screen itself — no paper towels, tissues, or cotton cloths, which can scratch the surface.
- For stubborn smudges on the screen, breathe gently on it to create a small amount of moisture, then wipe with the microfiber cloth.
- Never spray liquid directly onto the screen or use any cleaning products, including glass cleaner or disinfectant wipes.
- Clean the plastic bezel and stand with a barely damp cloth and distilled water only, keeping moisture away from the screen and ports.
What not to use on your monitor
Do not use paper towels, tissues, or cotton cloths. These materials are rougher than microfiber and can leave tiny scratches on the screen coating. Over time, these scratches dull the image and become visible when light hits the screen at an angle.
Never spray any liquid directly onto the screen — not water, not glass cleaner, not disinfectant wipes. Liquid can seep into the edges of the screen, damage the electronics underneath, or pool in the bezel and corrode the connections. Some cleaning products also dissolve the anti-glare coating or protective layer on modern monitors.
Avoid compressed air cans. The pressure can force dust into the vents and internal components, and the liquid propellant inside can spray onto the screen if you tilt the can. If dust is clogging the vents on the back or sides of your monitor, use a handheld vacuum with a brush attachment instead, held a few inches away.
Dealing with stubborn smudges and fingerprints
If a smudge does not come off with a dry microfiber cloth, breathe gently on the screen to create a small patch of condensation. This adds just enough moisture to loosen the smudge. Immediately wipe it away with the dry part of your microfiber cloth, using light circular motions.
If that does not work, dampen the microfiber cloth very slightly with distilled water — so slightly that it barely feels wet to the touch. Wring it out thoroughly. Wipe the smudge gently, then immediately dry the area with the dry part of the cloth to prevent water from pooling.
Do not let moisture sit on the screen. If you accidentally get the screen too wet, turn off and unplug the monitor immediately, and leave it unplugged for at least an hour to dry completely before turning it back on.
Cleaning the ports, cables, and stand
The back of your monitor has ports where cables connect — HDMI, DisplayPort, USB, or power connectors. Dust collects here and can eventually cause connection problems. Use a dry microfiber cloth or a soft brush to gently wipe around the ports and the cables themselves. Do not insert anything into the ports.
For the monitor stand and base, a barely damp cloth with distilled water works well. Wipe down the plastic or metal, then dry it immediately with a dry cloth. If the stand has grooves or textured areas where dust collects, use an old soft toothbrush to gently brush out the dust before wiping.
If your monitor has a removable stand that connects with a cable, you can unplug that cable before cleaning, which gives you better access. Just make sure the monitor is unplugged from power first, and reconnect the stand cable before plugging the monitor back in.
How often you should clean your monitor
In a typical home or office, a quick wipe with a dry microfiber cloth once a month is enough. If you work in a dusty environment, near a window with pollen, or in a home with pets, you may need to clean every two weeks.
Pay attention to the vents on the back and sides of your monitor. If you see dust buildup there, use a handheld vacuum with a brush attachment to clear it out. Clogged vents trap heat inside the monitor, which shortens its lifespan and can cause the image to flicker or dim.
Do not wait until the screen is visibly dirty to clean it. Regular light cleaning prevents dust from building up and reduces the chance of accidentally pressing too hard while trying to remove stubborn smudges.
Different monitor types and special considerations
Older LCD and LED monitors have a glossy or matte coating on the screen that can be sensitive to moisture. Newer monitors often have an anti-glare coating that is more durable but still requires the same gentle treatment. The cleaning method stays the same regardless — microfiber cloth, minimal pressure, no liquids on the screen.
Touchscreen monitors, which are less common in home use but found in some tablets and interactive displays, need the same care. The touch layer sits on top of the screen and can be damaged by harsh cloths or excessive moisture. Use only a microfiber cloth and avoid any liquid.
Curved monitors have the same screen coating as flat ones, so the cleaning method is identical. The curve does not change how you should treat the surface.
What to do if your monitor gets damaged during cleaning
If you accidentally scratch the screen, the damage is permanent and cannot be repaired. A small scratch may not affect the image much, but it will catch light and become more visible over time. If the scratch is in the center of your viewing area, you may eventually want to replace the monitor.
If liquid gets inside the monitor and you see flickering, dimming, or discoloration, turn it off and unplug it immediately. Leave it unplugged for several hours to dry. If the problem persists after drying, the internal electronics may be damaged and the monitor may need to be replaced.
If you spilled liquid near the power port or cables, unplug the monitor and let it dry for at least 24 hours before plugging it back in. If you see any burn marks, smell anything unusual, or the monitor does not turn on, do not try to use it — the internal components may be damaged.
Frequently Asked Questions
Can I use Clorox wipes or disinfectant wipes on my monitor?
No. Disinfectant wipes contain alcohol or other chemicals that dissolve the protective coating on monitor screens. They also introduce too much moisture. Stick to a dry microfiber cloth, or use distilled water on the cloth only if absolutely necessary.
Is it okay to use a screen protector on my monitor?
Screen protectors are designed for phones and tablets, not computer monitors. They reduce image clarity, can trap dust underneath, and are difficult to apply evenly to a large flat surface. Keep your monitor clean instead of covering it.
What should I do if my monitor has a matte finish instead of glossy?
The cleaning method is the same. Matte screens have a textured coating that reduces glare, but they are just as sensitive to scratches and moisture as glossy screens. Use a microfiber cloth and avoid any liquid unless absolutely necessary.
Can I clean the inside of my monitor if dust is visible through the screen?
No. Opening a monitor voids the warranty and risks damaging the electronics or getting shocked by residual electrical charge. If dust is visible inside, contact the manufacturer or a repair shop. For dust on the outside vents, use a handheld vacuum as described above.
How do I clean the monitor if it has a glossy screen protector attached?
If your monitor came with a removable protective film, peel it off before cleaning — it is meant to protect the screen during shipping, not for long-term use. If your monitor has a built-in glossy coating, treat it the same as any other monitor: microfiber cloth, no liquids on the screen itself.
