There are countless ways you can wipe and dust your laptop clean — but some tactics are definitely better than others. The best laptop cleaners get rid of smudges on your screen and crumbs between your keys, and they do so without damaging delicate hardware. That said, the best choice for you is largely going to depend on your needs:
Sprays: Sprays are best-suited for screens and other non-porous surfaces. (You don't want to use a spray directly on a keyboard, as the moisture could drip between the keys and destroy the electronic components.) The best sprays are non-streaking and free from harmful additives.
Wipes: Since they're often pre-moistened and individually wrapped, wipes are one of the easiest and most portable ways to clean your laptop. They're primarily used on the screen, but so long as they're not dripping wet, you can also use them on your keyboard. For the best results, look for a solution that's anti-static, streak-resistant, and free from unwanted chemicals.
Vacuums: A small keyboard vacuum can suck up dust, hair, crumbs, and residue from your laptop. If your vacuum is compact, handheld, and rechargeable, it'll be much easier to use and store.
Brushes: The right electronics brush can sweep away dust and crumbs. Make sure that the bristles are soft and won't scratch your laptop. (Some even have built-in screen cleaners.)
Cleaning gels: This cleaning solution has a putty-like consistency, which grabs onto dirt and residue in hard-to-reach places. While it's on the moist side, it won't damage unexposed electronics the way a spray might. Find one that's reusable and made from safe materials.
Compressed air dusters: Air dusters blow compressed air into cracks and crevices, so it's the easiest (and safest) way to clean sensitive circuitry. While compressed air is sold in a can, it's not the most eco-friendly choice, and a motorized unit may help save money over time.
