But have you ever thought of cleaning/disinfecting the outside of your computer? When I clean my computer I always include the monitor/screen, keyboard, and mouse/trackpad.

Speaking of our keyboards and mouse, did you know that they are a haven for bacteria? Just like our smartphones, tablets, kitchen sponges, cleaning towels, and even your dog/cat bowls!

And now with the current COVID-19 pandemic of 2020, disinfecting all surfaces in our homes must include all computers and related equipment (specifically that we touch with our hands).

Cleaning the Keyboard

A computer (desktop and laptop) keyboard can collect dust, food, liquid, and other particles that get stuck in between and underneath the keys and buttons.

It’s best to turn your computer off OR disconnect the keyboard so as to not cause any strange issues while working on it.


If it’s a desktop keyboard, hold it over a garbage can (or outside) then flip the keyboard upside down and gently shake or tap it to remove dirt and dust.


For both a regular desktop keyboard and a laptop keyboard, you can use a can of compressed air to clean between the keys and buttons.

Bonus Tip: You can also use the compressed air to clean out the vents and open ports on both a desktop and laptop computer (great for TVs too!). 🙂


Next, apply rubbing alcohol (at least 70%) to a paper towel or microfiber cloth and use it to clean the tops of the keys (and buttons) and a track/touchpad if you have one. If cleaning a laptop, wipe down the whole “top deck” (the area surrounding the keyboard).

Never pour, or spray, any liquid directly onto the keys!


And finally, once the keyboard is dry, reconnect the keyboard to the computer (or turn on the computer).

Cleaning the Mouse

The following cleaning tips will help keep your mouse clean:


Unplug the mouse from the computer — or turn off the mouse if it is wireless.


Next, apply rubbing alcohol (at least 70%) to a paper towel or microfiber cloth and use it to clean all sides of the of the mouse (top, bottom, sides).

Never pour, or spray, any liquid directly onto a computer mouse!


And finally, reconnect the mouse to the computer (or turn on the computer) once it is dry.

Cleaning the Monitor

Dirt, dust, and fingerprints can make your computer screen difficult to read. But thankfully it is very easy to clean your screen.

I generally advise people that they can use any glass cleaner, as long as it doesn’t have ammonia, to clean their computer monitor and/or TV screens.

But the two best cleaning solutions that I use is either water or a glass cleaner called Sprayway (which I use for all of my screens, windows, and mirrors).


Turn off the computer before cleaning the monitor, just in case.

Never spray any liquids directly onto the screen. The liquid could leak into the monitor and damage internal components.


Next, apply water or Sprayway to a paper towel or microfiber cloth and use it to clean the screen.

Never pour, or spray, any liquid directly onto a computer mouse!

Other Computer Surfaces

While you are at it, you might as well wipe down the rest of the computer. I always use microfiber towels on my technology equipment. And use the compressed air to clear out any vents or open ports. Be careful, there will probably be a lot of dust coming out.

You can vacuum up any dust that falls out, just don’t use the vacuum on the computer itself!
