Do’s and Don’ts of Cleaning Electronics

How many people think about cleaning electronics? You use them every day, and some devices have even become an integral part of life such as laptops, phones, and headphones. Your homes are squeaky clean, but when was the last time you took a good look at your gadgets and appliances? Just bring your phone closer to the eye and check the display, corners, and crevices. Ew!

The truth is even scarier. The electronics have dirt, and they are more ick-infested than the toilet seats in public restrooms! Several studies have found that the household toilet seats have 50 to 300 bacteria per square in an average while it is more than 1,000 in public lavatories. Your handheld devices harbor even more!

What is the right way of cleaning electronics to remove the dirt and germs? Well, cleaning a computer is totally different than mopping the floor or washing the dishes. Electronics are sensitive devices, and you can damage or ruin them by following the wrong procedure or using harsh cleaning agents.

The Do’s and Don’ts of Cleaning Electronics

Keeping all your expensive gadgets in tip-top condition is vital for their proper function and stopping the spread of diseases. However, you can’t just spray a cleaner on them and rub with a paper towel. Also, the maintenance and cleaning procedures will be different depending on the device types. Let’s see the proper ways of dusting and wiping some household items and commonly-used gadgets.

Laptops and Notebooks

You transfer these dirt particles to your body and other places every time you use the coffee machine, grab the snacks, or rub your eyes after using the laptop.


  •         The laptop should be turned off before cleaning the monitor and other parts. In case if you use an extra keyboard, unplug or turn it off.
  •         Spray cleaning solution on a microfiber towel to wipe down your screen, mouse, and other flat surfaces. The rubbing pattern should be from left to right. It will make the dust particles come off easily without scratching the surface.
  •         Turn the open laptop upside down (or the keyboard if it’s separate) and shake off particles trapped between the keys. Then, use a soft brush to dust off. A can of compressed air or a small vacuum cleaner (designed for dusting small electronics) can force out the dirt between the keys. You can use the vacuum to clean the cable and USB ports of the laptop and the crevices inside the mouse.
  •         Rub the keyboard with a cleaner-dipped microfiber cloth because some keys such as the space bar and Enter become grubby due to frequent use.
  •         A cleaning agent like Mr. Clean Magic Eraser will do wonder for an oily keyboard. However, if you have never cleaned it after buying, open the screws with a screwdriver, pop out the keys and scrub with a toothbrush.
  •         Do the cleaning at least once in a month.


  •         Don’t use a regular vacuum cleaner for the keyboard. The suction force is so powerful that it will pull off the keys and damage the internal components.
  •         Don’t spray the cleaner directly on the screen or keyboard.
  •         Never turn on the laptop if it is not completely dry.
  •         Get rid of the habit of eating at your desk.

Smartphones and Tablets

  •         Direct spraying of a liquid cleaning solution is strictly prohibited. Moisture or drops of the solution may get inside and damage the internal circuits.
  •         Never use a hair dryer to dry up the gadgets. Electronics are sensitive, and the direct application of hot air can damage their delicate components.

Also, cleaning electronics like these devices are necessary to keep them functioning.
