Here’s how to clean your laptop keyboard

Have you got everything you need? Well, read on to find out how to clean your laptop keyboard in no time.

1) Turn over and shake the PC

First, it is recommended to turn the laptop upside down while it is open and shake it gently to remove the larger debris stuck between the keys and facilitate subsequent steps.

2) Wipe the keys with a soft cloth

After removing the largest residues, quickly wipe the keyboard with a soft damp cloth, preferably microfiber and antistatic. This will remove some of the dirt accumulated on the keyboard.

3) Use compressed air

Now you can take your can of compressed air and spray it on the keyboard to remove the residual dust and dirt trapped between and under the keys. Make sure the straw adheres well to the can before spraying. Then tilt your keyboard and spray compressed air between the keys making short clicks. Never use the can holding it upside down to prevent the propellant from escaping and penetrating the keyboard, damaging its internal components.

4) Use a USB vacuum cleaner

Be careful not to use a regular vacuum cleaner to clean your laptop keyboard. Many keyboards have retractable keys and you risk sucking them out. As an alternative to compressed air, you could instead buy a vacuum cleaner with USB power, specially designed for cleaning keyboards.

5) Use Cleaning Slime

Cleaning slime, also known as magic eraser, is not essential for cleaning the keyboard. However, it is extremely effective as it molds itself perfectly to the keys and slots of the keyboard and, thanks to its rubbery texture, captures all debris and dirt residues in just a few seconds.

6) Remove stubborn residues with isopropyl alcohol

After removing the dust and debris stuck under and between the keys, you should take care of the stubborn dirt. To remove oily residues or sweat left from your fingers, moisten a cotton swab with isopropyl alcohol. The latter evaporates very quickly and is therefore much safer than water. Quickly slide the cotton swab between the keys and then make sure to dry the keyboard thoroughly with a soft cloth to prevent moisture build-up.

7) Disinfect the keys with wipes

Now is the time to get rid of germs and bacteria. In particular, if you use a shared device, you can disinfect the laptop keyboard using disinfectant wet wipes, such as Lysol or Clorox, making sure to squeeze them before use to remove excess moisture. Never use wipes that contain bleach and do not spray disinfectant sprays or liquid cleaners directly on the keys to prevent moisture build-up from damaging the internal electronic components of the PC.
