Clean Your Laptop’s USB Port Properly And Avoid Breaking It In The Attempt.

It seems silly, but many people have broken their USB port because they did not know how to properly clean its interior. Learn this cleaning tutorial to avoid problems.

We don’t care about the state of our USB port until it fails, right? We’ve all done it, and once or twice we’ve blown inside because there were recognition problems. That’s why we’ve come up with a cleaning guide with the goal of getting your USB ports clean, disinfected and 100% operational.

How to clean a USB Type-C or Type-A slot on your laptop

Many people wonder if they need to be cleaned differently, but let us tell you that this guide works for both types of ports. We are going to show you how to clean it without damaging it.

What not to do

First of all, we are going to summarize what you should not do when cleaning your USB because, otherwise, you will damage it.

Start by understanding that you should not use metal instruments to remove dirt from the port because you may damage the pins inside the port. Also, turn off the laptop you are going to clean the USB port because we don’t want any surprises.

Use compressed air with care

We start with compressed air, but from a safe distance, it is not necessary to put the nozzle inside the port. In this way, we will expel the residues inside the USB port of the laptop.

In this sense, straw-shaped nozzles are more advisable because they allow you to focus each spray into the port. You have to use short and controlled bursts, as well as hold the can upwards so as not to eject the liquid content of the can.

Toothbrush for solid dirt

Logically, debris stuck inside the USB port will not come out when using compressed air. Therefore, we can use a toothbrush (or a brush) to pass the fine fibers of the brush through the inside of the port.

Toothpicks will also work, even dental floss, but it is much more convenient to use a toothbrush or toothbrush.

Isopropyl alcohol to moisten the dirt.

Dirt may be so stuck to the USB port of the laptop that a toothbrush or derivatives will not work, so you have to resort to isopropyl alcohol to moisten it. In this way, we will be able to soften it and it will be easier to extract the residues from the port of the laptop.

You can use isopropyl alcohol in spray form (if you have it), but if you have it in liquid form, it is best to use a cotton swab or toothbrush. You can impregnate them with isopropyl alcohol.

We remind you not to use water or distilled water for these tasks because the electronic components do not get along well with water due to humidity.

As a tip, we recommend flattening the head of the swab with a pair of pliers so that it fits into the USB slot. Then dip it in isopropyl alcohol and insert it into the ports.

You are done when you see the contacts shining or much cleaner. Then wait 10 minutes for the alcohol to evaporate before using the device again.

Cyber Clean

Cyber clean is a curious product that consists of a moldable rubber that sticks any dirt in its path. Many people use it because, thanks to the fact that it is moldable, it can be put through cracks in fans or small places, such as our ports.

Also, you can use it for other purposes that have nothing to do with your USBs or PC.

3-in-1 contact cleaner spray

Although its use is generic, it can be used to clean our USB port. It is a simple spray that acts and dries quickly without leaving residues, as is the case with isopropyl alcohol.

Before using it you should disconnect or turn off the device to prevent any problems that may arise.

Tips for keeping your laptop’s USB port clean

Prevention is better than cure, so it is interesting to know how to keep our USB slot clean to avoid having to do this process continuously. We can summarize the tips in these:

Watch how you transport the device. In case it is a laptop, maybe it gets dirty because your suitcase or backpack is dirty. If it is not, change its arrangement inside it because that may be what is going wrong.

Tape when not in use. This is an option worth noting because it works so well. The problem with this workaround is that the tape loses adhesion to the port as it is applied and removed.

Plug, the best option to clean your USB port. If you have bought a new TV or monitor, you will have seen that its HDMI or USB ports come with plugs to prevent them from getting dirty, right? Well, you can buy these dust caps on Amazon for USB Type-A and Type-C.


We hope this information has been helpful. Put our tips into practice and keep your laptop usb ports clean and functional at all times.
