Although it is possible protect USB-C ports of many devices using a suitable case, a plug or even just a piece of tape, sooner or later the time will come when it will be necessary proceed with a thorough cleaning.
That’s because it’s easy for debris to accumulate in such a small space, especially when it comes to a smartphone that you often keep in a pocket full of lint. So, let’s see together how to clean any USB-C port in a minute or two, and what to avoid in the process.
The checklist for cleaning a USB-C port
The general principle is one: pay attention. If you damage the electronics of the porta USB-C, the connection may stop working. The worst thing would be to short the entire device, although that’s unlikely.
First of all, blow air on the door to remove dirt and debris. If you’re lucky, this may be all you need to do, but you’ll probably need one can of compressed air. Hold the nozzle straw directly to the port and use bursts of one second each. Be sure to hold the can perfectly upright, as tipping it may cause liquid to leak.
If you think there is still debris in the door, get one toothpick, a small dental cleaning implement, or something similar that is not metal, sharp, or hairy. Due to its size, if you decide to use a wooden toothpick, you may need to file it down.
Then, insert the cleaning stick and gently working the sides, scrape off the debris. The principle is to try to avoid the USB connector pin at the bottom. At this point, use another gust of air to force out any newly loosened debris. If there is still material in the port, repeat steps 2 to 4.
The common mistakes when cleaning the USB-C port
While some of these tips may seem obvious, it’s important to always keep them in mind.
First of all, avoid inserting anything directly into porta USB C. That’s where the connector pin is, and doing so could damage the pin or scratch the power or data contacts.
The other tip is to do not use a cotton swab. It’s probably too big for a USB-C port, but the biggest risk is leaving lint behind, swapping out one type of dirt for another.
Do not use metal or sharp objects. Indeed, they are more prone to damage the electronics and, in the worst case, could cause a short circuit and ruin the whole device.
In the end, avoid getting liquids in into the port, either from a can of compressed air or otherwise. If this happens, make sure the device is turned off and let it dry. You can use cold air to speed up the process, but not a hot hair dryer.
