A USB-C port is a handy feature of various electronics that can help transfer data over a small distance. However, these ports are open spaces into the device that can become clogged with dirt and become faulty.  

If you are looking for tips on how to finally clean your USB-C port, we have plenty of advice in this handy guide. 

What Is A USB-C Port And How Does It Work? 

A USB-C port is a standard cable connection interface for many modern computers and electronics. They are a newer standard to support thinner cable types and form factors than previous editions USB-A and USB-B.

These USB-C ports are typically used to hold USB cables. There are many devices that utilize USB ports such as printers, network adapters, USB drives, monitors, and other compatible devices. Most people who interact with modern technology have used a USB port at some point in their personal or professional lives.

Why Should You Clean Your Phone/Laptop's USB-C Port? 

Because you typically carry your phone and laptop around to use in everyday life, these open spaces will inevitably gather dirt. It is not something we typically think about, but not cleaning these handy devices once a month can inhibit or damage the function of your beloved tech.  

Dirt build-up in USB-C ports can make the ports less efficient, slow the transmission of data, and cause your device to disconnect the power while in use. 

Signs That A USB-C Port Needs Cleaning 

  • The USB-C Port Doesn’t Charge 
    While it is easy to assume that your port has simply worn down or has software issues, the solution may be simpler than getting a new device. Dirt build-up can get in the way of the connection between a USB cable insert and the port interior. 
  • The USB-C Port Can’t Transfer Data  
    Electronics may seem to have a habit of stopping functioning when you are in a hurry or doing important things. However, instead of groaning in frustration, you may find that cleaning the port and groaning in irritation can restore the port. 
  • Cables Don’t Click Into Place In The USB Port   
    A cable can only properly work within the port when connected with a click. If the cable feels loose or does not click, there may be dirt build-up getting in the way; cleaning should quickly resolve the issue. 

4 Ways To Clean USB-C Ports (DIY Guide Without Damage) 

Knowing how to clean a USB port is part of the battle. There are a few different ways to clean your USB-C port that are cheap and easy to do.
