How to Clean Your Laptop, Keyboard and Monitor Safely

Dust is not just cosmetic: it insulates laptop heatsinks, makes fans louder, and turns keyboards into something you’d rather not think about. The good news is that a proper clean takes about 30 minutes, needs almost nothing you don’t already own, and visibly extends how long your gear stays pleasant to use. Here’s how to do it without damaging anything.

Rules that prevent damage

• Power off and unplug everything first; remove batteries where possible.
• Never spray liquid onto a device. Dampen the cloth instead.
• No ammonia-based glass cleaner on screens — it can strip anti-glare coatings.
• Check the manufacturer’s guidance before using alcohol on a display; some coatings tolerate it, others don’t.
• Don’t spin fans with compressed air — hold the blade still with a finger or a swab.
• Keep compressed air upright and use short bursts, so no propellant liquid sprays out.

Screens and monitors

1. Turn the display off so marks are visible against the dark screen.
2. Dust gently with a dry microfiber cloth, top to bottom.
3. For fingerprints, lightly dampen the cloth with distilled water and wipe in one direction, without pressing.
4. Dry with the second cloth.
5. Clean the bezel and stand with an alcohol wipe, avoiding the panel edge.

Keyboards

Laptop and low-profile keyboards

Tip the keyboard and use short bursts of air between the keys, then wipe the keycaps with a barely damp cloth or an alcohol wipe. A soft brush dislodges what air misses. Don’t pry laptop keycaps off — the scissor clips break easily.

Mechanical keyboards

Photograph the layout first, then pull the keycaps with a puller. Wash the caps in warm water with a little dish soap, and let them dry completely — overnight is safest. Meanwhile, brush and blow out the plate, and wipe it with a lightly dampened swab. Reassemble from the photo.

Laptop vents and fans

If your laptop runs hot or the fan is constantly loud, dust in the vents is a likely cause. Blow air into the exhaust vents in short bursts with the laptop off, so dust exits the intake side rather than packing deeper into the heatsink. Opening the laptop for a proper clean gives far better results — but check whether it affects your warranty, and see our battery guide for safe handling once you’re inside.

Use the laptop on hard surfaces, not on a bed or sofa, which block intakes and accelerate dust build-up. A laptop stand helps airflow as well as posture.

Mice, headsets and desk

• Mouse: clean the feet and sensor window with a dry swab; grime on the feet makes tracking feel sticky.
• Headset: wipe ear cushions with a slightly damp cloth; replace them when they flake.
• Webcam lens: a dry microfiber wipe — it’s usually the reason your video looks hazy.
• Desk mat: most fabric mats can be washed; check the label.
• Cables: a good moment to redo the routing — see our cable management guide.
