Because we use our laptops and computers so much, they are a hotbed for crumbs, dirt and debris that can not only leave your laptop looking unsightly, but can damage its performance in the long run. Never use household cleaners to clean electronics, and don’t use vinegar instead of alcohol — it could seep into the keyboard and corrode its components.
Use the can of compressed air to remove any dust, lint and crumbs that could have found a way into the hinge between the keyboard base and the screen.
Do the same for the laptop keys, making sure you get in-between crevices.
If your laptop has side vents, you should also use compressed air to blow out any dust and debris that has managed to get caught inside.
Use short sharp bursts instead of just blasting it straight through, otherwise you can risk getting condensation between keys.
Alternatively, you can use a small amount of blue tac and dab it across the crack and between the keys to get out any debris.
Next, dab a small section of your cloth with isopropyl alcohol and wipe over the keys.
Make sure to get into the spaces in the keys so that nothing is left behind.
Use a cotton swab to get into any harder-to-reach spots, like the hinge between the screen and body.
Isopropyl is the best option for cleaning laptops as it is antibacterial and evaporates almost immediately, meaning there is little risk of any liquid seeping into your laptop and causing damage.
If you need to clean the inside of your laptop, its best to ask the manufacturer what to do, as opening and cleaning your laptop can invalidate your warranty.
