Clean a laptop with the machine switched off and unplugged, using a soft, lint-free cloth that is barely damp. Go gently, keep liquid away from openings, and follow the maker’s care instructions for your model. The steps below cover the screen, the keyboard and the case.
Gather Your Supplies
- Two soft, lint-free cloths, such as the kind used for glasses.
- Clean water, or a cleaning product the maker approves for screens.
- A soft brush with fine bristles.
- Cotton swabs for edges and gaps.
Avoid kitchen sprays, strong solvents and rough paper towels, which may damage coatings or scratch the surface. Check the maker’s guide for what to avoid.
Cleaning the Screen
- Shut the laptop down, unplug the charger and let it cool.
- Remove loose dust with a dry cloth, wiping lightly in one direction.
- Dampen the second cloth very slightly. Never spray liquid straight onto the screen.
- Wipe gently from top to bottom, without pressing hard.
- Dry with the first cloth to avoid streaks.
- Leave the screen open for a minute before closing the lid.
Cleaning the Keyboard
- Tilt the laptop gently and tap the base lightly so loose crumbs can fall out.
- Run the soft brush between the keys.
- Use a barely damp cotton swab around key edges, taking care that no liquid runs between keys.
- Wipe the key tops with the damp cloth, then dry them.
Where to Take Extra Care
| Area | Care point |
|---|---|
| Screen | Light pressure only, as it can mark or mark pixels |
| Keys | Do not pry them off unless the maker shows how |
| Ports and vents | Keep liquid out; brush dust away gently |
| Trackpad | Use a lightly damp cloth, then dry |
Everyday habits that cut down on cleaning. Wash your hands before long sessions and keep drinks well away from the keyboard. Close the lid gently, and keep a clean cloth in the bag for quick wipes. Do not eat over the keys, because crumbs find their way under them.
If something spills, switch the laptop off at once, unplug it, turn it so the liquid runs away from the keys and follow the maker’s instructions for spills. Do not try to switch it back on to see whether it works. A repair service can advise if the liquid got inside.
Dry thoroughly before using the laptop again, and leave it open in a cool, airy place while it dries.
FAQ
How often should I clean it?
A quick dry wipe weekly and a fuller clean when it looks dirty is a common routine. Adjust to how you use it.
Can I use compressed air?
Some makers advise against it, since it can push dust inward. Check your guide before you try it.
The Short Version
Power off, unplug, and use soft, lightly damp cloths with gentle pressure. Keep moisture out of openings, avoid harsh products, and follow the maker’s instructions for your laptop.
