Like the various other pieces of equipment and appliances at your home, your treasured laptop, too, requires periodic cleaning.

You can either choose to use specially formulated cleaning products and solvents or simply some household cleaners for this purpose.

While cleaning, though, you need to avoid using cleaning solutions or procedures that could prove to be damaging.


Thus, make sure you read your computer’s user manual thoroughly, especially the instructions for cleaning and maintenance.

How to Clean a Laptop

Steps for cleaning

  1. Turn off and unplug your laptop.
  2. Create a cleaning solution at home by mixing one part of isopropyl alcohol (rubbing alcohol) and one part distilled water. Alternatively, you can combine distilled water with white vinegar in equal proportions. Pour this solution in an empty spray bottle (preferably an atomizer bottle).
  3. Spray the solution on a piece of soft, lint-free cotton cloth, rag, cotton ball, microfiber cloth, etc. and wipe the screen with it in small and gentle circular motions to avoid streaks. Do not apply too much pressure on the screen while cleaning so that you do not cause damage to the LCD matrix.
    Moreover, make sure you moisten the cloth with the cleaning solution and do not drench it entirely to avoid dripping. Keep in mind that you are not supposed to spray the fluid directly on to the screen as the drops can seep in the bezel or even the keyboard.
  4. Take another clean cloth, spray it with water, and clean the laptop screen with it in continuous motion while applying even pressure. If your screen looks crystal clean with the previous step itself, you may skip this step.
    As alcohol tends to evaporate soon, it is less likely to leave streaks. Allow the screen air dry for a few minutes before closing the lid.
  5. Next, wipe down the exterior of the laptop in the same way.
  6. In case the keyboard has collected dust and grime then you can moisten a soft cotton cloth with water or isopropyl alcohol and distilled water mix and wipe the keys and even the touchpad with it.
    Again, make sure the cloth is not too wet. Furthermore, remember not to use the same dirty cloth for cleaning your laptop next time.
  7. Plug in the power adapter and battery when the laptop dries completely.

Isopropyl alcohol can help remove oil stains and grime. Thus, you can use distilled water in the spray bottle if you need to get rid of dust from the laptop.

If you have a can of compressed air (available at most department stores), you can spray it on your laptop, including the keyboard and case openings to get rid of surface dust.

compressed air

When spraying compressed air on the computer’s fan, it is suggested to place an object like a toothpick, the Q-tip you used, or some other object in-between the blades of the fan, otherwise it may over spin.

Instead of compressed air, a vacuum cleaner can also be used with its tiniest attachment to suck the dirt and crumbs in-between the keys.

Also, you may sweep the space between the keys with a Q-tip to remove particles of dust. However, do not insert the Q-tip into the ports or holes.

Additional Tips

  • Use a soft and non-abrasive cloth for cleaning your laptop. Even paper towels and tissues should be avoided as they contain wood fibers. You can use a clean eyeglass cleaning cloth, though. Interestingly, if you
  • It is suggested to avoid cleaning the laptop with regular or tap water as it may contain minerals and chemicals. Furthermore, do not use soap solutions, window cleaners, or other similar detergents as they can harm the screen. Ammonia and other strong solvents should also be avoided.
  • To avoid getting finger prints and gunk on your screen, do not touch the screen with your smudgy fingers.
  • In case you are not sure about using household products for cleaning your laptop, consider using commercially available wet or dry wipes specifically designed for cleaning LCD screens.
