Cleaning your keyboard is essential for maintaining hygiene, preventing the transmission of diseases and ensuring a pleasant working experience. After all, the keyboard carries over 3 million bacteria, about 20 thousand times more than a chair or bench.

The keyboard is second only to the ID card, which leads the ranking with over 4 million bacteria.

In this tutorial, we’ll teach you step-by-step how to clean your keyboard: we’ll cover both traditional membrane and mechanical keyboards, as well as laptops in general.

Disconnect the power supply

Everything, absolutely everything you clean needs to be unplugged. Even if you don’t use liquids (such as alcohol), rubbing the cloth with electronic equipment can generate static electricity and therefore a short circuit.

As for the laptop keyboard, it’s important to start cleaning with the computer turned off, so you avoid pressing the wrong keys and the computer starting to run things it shouldn’t.

Cleaning the keyboard in “dry” mode

Start by removing physical debris. Turn your laptop or keyboard upside down and gently tap on the keys to remove any dirt accumulated inside the keys. This won’t remove everything and won’t guarantee the device will be sanitized, but it will remove larger debris.

If you have a vacuum cleaner handy, now is the time to use it. Carefully wipe every dust entry point on the keyboard. You can also use a special compressed air gun for cleaning electronic equipment, but be careful, it is powerful. Therefore, use it at short intervals and not constantly. But if you don’t have a vacuum cleaner or compressed air machine, blow gently.

Don’t forget that the air you push out must also come out with the dust. Never blow or spray compressed air directly onto the keyboard but into the specific slot under each key, as it is easier for something to get underneath and get stuck – than to come out.

Remove the keys

On some keyboards it’s common for grease and dust to build up and turn into a kind of glue. To remove it perfectly you need to remove the keys.

Conventional membrane keyboards and mechanical keyboards have keys that are easy to remove. However, the process on some laptops can be terrible. So, research the model of keyboard you have before removing the keys. If you can’t remove them, you can try to get at the dirt with flexible cotton-tipped swabs.

Sanitise surfaces

It’s time to sanitise the keys. To clean them, apply a little alcohol to a soft cloth, ideally microfibre. Don’t forget the space between the keys.

Use the alcohol wipe to clean the keys and, in the case of a laptop, the rest of the equipment, but pay particular attention to the device’s screen.

Finally, everything is clean! Put the keys back in place and, before plugging them in, make sure the equipment is completely dry.
