Making Use of Rubbing Alcohol

Isopropyl alcohol, also known as rubbing alcohol, is a common household item with various uses ranging from antiseptic to cleaner.

It’s perfect for cleaning electronics because it vaporizes quickly and doesn’t leave any residue behind.

Choose one with greater alcohol content, as those with less than 70% alcohol concentration may take longer to dry up.

A cotton swab is required to utilize this successfully. Use the alcohol to wet the swab and use it to reach into the USB port.

After that, gently rub the swab across the port’s inside, collecting as much dirt as possible. The moist swab can remove more dirt, and alcohol is a fantastic solvent for removing even stubborn stuff.

Drawbacks of Rubbing Alcohol

Depending on the degree of alcohol you apply, it may take a few hours for the ports to dry fully.

At the same time, if you aren’t careful with the cotton swabs, you may inadvertently push the dirt deeper into the port.

Making Use of Compressed Air

How To Clean USB Port On Laptop?

Cleaning the dirt and debris out of a laptop’s USB ports using compressed air. It’s also used to wipe the remainder of the laptop clean.

If you have one, you can use an electric blower to help with this. If not, a can of compressed air can be obtained at a reasonable price and used instead.

With each approach, the heavier clumps of dirt or dust balls inside the USB ports must be removed first.

After that, insert the nozzle of the can or the blower into the USB port at an angle. The high-pressure air will flow into the USB port once turned on, driving dust and other particles out.

You won’t be forcing dust into your laptop’s internals because the USB ports’ back ends don’t open into the internal body of the machine.

However, you’ll need to slant the nozzle to avoid pushing the dust deeper into the USB port and making things worse.

Drawbacks of using Compressed Air

Unless you already own a blower or compressed air can, you may need to purchase one, which can be costly.

At the same time, compressed air can run out over time, so if you choose to use them, you will need to buy a new one every time it runs out. 

Using a Contact Cleaner

Contact cleansers are a class of chemical products used to remove dirt and other undesired buildups off conductive surfaces of electronics, including USB ports.

If your USB ports have a buildup of anything from dirt to debris, contact cleaners can be used to clean them out, and some can even remove rust.

You may need to turn off your computer, disconnect power, and even let it cool down a little, as with each process. After that, you can clear it out with a contact cleaner.

A WD-40 Specialist is a well-known brand. All you have to do is spray the port with the contents of the can, and don’t be put off by the fact that the spray is liquid.

Before moving on to the next port, give each one a good spray and ensure it’s clean. The solution dries quickly, and you can get back to work on your computer right away.

It effectively removes dirt, residues, and even oil from your ports, leaving them clean.

Drawbacks of using a Contact Cleaner

The biggest disadvantage of utilizing a contact cleaner is that a single can be quite expensive for certain people.

Use a Toothpick

How To Clean USB Port On Laptop?

To remove any leftover debris, use a toothpick after trying compressed air. Toothpicks will not fit through the hole in the port. The pointed end of the toothpick must be taken off with diagonal cutters. Cut the toothpick’s flat edge to fit into the port. Remove any splinters with a knife. The hole can be stitched with a toothpick. If there’s anything stuck within, gently push it in and wiggle it out. You don’t want to poke it so hard that debris gets stuck in the USB-C controller chip. Toothpicks are effective because they are narrow enough to fit into the port while firm enough to remove debris. They’re also small enough to manipulate with your hands.

Use a Disposable Dental Floss

The pick on the end of a disposable dental floss is much thinner than a toothpick and is great for cleaning the USB-C port on your smartphone or laptop.
