USB-C charging ports are common in modern laptops, gaming systems, phones, and tablets, offering a universal solution for charging and data transfer. However, like other exposed electronic ports, USB-C ports can collect dust, grime, and debris over time.
If you find it difficult to insert a cable or your device isn't charging properly, the port could be dirty. This article teaches you how to safely remove dirt and other substances from your USB-C charging port using simple household items.
Step 1: Gather Your Cleaning Materials
Before you start, ensure you have a clean, flat surface with sufficient lighting. Gather the following supplies, many of which you may already have around the house:
-
A can of compressed air
-
A plastic dental pick (or a wooden toothpick shaved to fit the port)
-
A small amount of cotton
-
70% isopropyl alcohol (or a quick-drying electronics cleaner made specifically for cleaning ports, sensors, and other electronics)
Step 2: Turn Off Your Device
Whether you're cleaning the USB-C charging port of a laptop, Nintendo Switch, phone, camera, or other device, make sure it is fully powered down before you begin. This step is crucial to avoid any electrical damage during the cleaning process.
Step 3: Spray Quick Bursts of Compressed Air into the Port
Using the can of compressed air, spray quick bursts of air into the port. Bursts of one to two seconds should be enough to loosen debris. Repeat this several times at different angles until the port is clear. Most cans of compressed air come with a straw-like nozzle attachment, allowing you to spray concentrated bursts right into the port.
If possible, hold the device upright so that the charging port faces downward, and then spray upward into the port. This allows excess debris to fall from the port to your working surface.
Step 4: Drag a Dental Pick Around the Edges of the Port
If there’s a substance inside the port that can’t be removed with air, use the sharp end of a plastic dental pick or a narrow toothpick. Avoid using anything too sharp, like a needle. Be firm but not rough; you don’t want to loosen the port. Don’t blow into the port with your mouth to loosen the gunk you remove with the dental pick—this could introduce excess moisture into the port and damage the internal components. Instead, hold the device with the port facing down and blow it free with compressed air.
Step 5: Use Isopropyl Alcohol for Sticky Substances
If the port has some sort of gunk or goo inside, wrap a small amount of cotton around the end of the dental pick and dampen the cotton with a small amount of isopropyl alcohol. Circle the inside of the port with the cotton end until you've removed the substance.
Don’t get the cotton too wet with alcohol—just enough to dampen it. Be careful not to get rubbing alcohol anywhere else on your device, as it can ruin certain oleophobic screen coatings and rubber seals inside waterproof phones and tablets. You can put low-intensity rubbing alcohol on a Q-tip and gently wipe the area with it.
Step 6: Keep Your Port Covered in the Future
Since USB-C charging ports are commonly available for devices made to be taken out of the home or office, these ports are often exposed to a fair amount of dust and debris. Take smartphones, for example, which you may stick into your coat pocket, leave on a dirty table, or throw into a dusty purse. Some ideas for keeping your port clean:
-
Cover the port with a small strip of adhesive tape when you’re not using it. This may leave a little residue on the port over time, but you can easily clean it off with isopropyl alcohol and cotton.
-
Use a case that covers the port when you’re not using the device. Most phone and tablet cases leave USB-C charging ports exposed for ease of use, but you can opt for one that doesn’t.
-
Purchase a USB-C dust plug—a small plastic or silicone plug that fits inside your port when you’re not using it. These small pieces are easy to find at electronics stores and other retailers.
Conclusion
Cleaning your USB-C charging port regularly is essential for maintaining the performance and longevity of your device. By following the steps outlined in this guide, you can easily remove dust, dirt, and debris from your port, ensuring a reliable connection and efficient charging.
Remember to keep your port covered when not in use to prevent future buildup. Regular maintenance will save you time and potential repair costs, keeping your devices functioning smoothly.
