How to clean your phone’s USB port




Given the life of our phones, it’s no wonder their ports need a little TLC from time to time. No matter how rugged your smartphone is, or how rugged your phone case is, the USB port is bound to accumulate dirt and dust after prolonged rough use, especially with regular exposure to the elements. If your USB-C port has stopped working or looks a little dusty, here’s how to clean it safely.


  • Dust and debris can prevent your phone’s USB-C port from working properly.
  • A can of compressed air is the safest way to clean your phone’s USB port.
  • Do not use liquid inside your phone’s USB-C port.

The best way to clean your phone’s USB port

The USB port on your phone is sensitive, so you’ll need a gentle hand to clean it. By far the safest way to clean the USB port on your phone is with compressed air. The compressed air will loosen the dust and blow out the dirt without having to put anything in the port.

The use of compressed air speaks for itself, but we’ll give you a quick overview anyway.

  1. Position the compressed air nozzle a short distance from the USB port.
  2. Always keep the jar upright.
  3. Use short bursts of compressed air to remove dust and debris.

While you can just as easily blow into a USB port, a can of compressed air is more powerful, and there’s less chance of liquid accidentally entering the port.

Removing stubborn dirt from your phone’s USB port

If your USB port is still clogged with dirt, it’s time to dig a little deeper. At this point, we should mention that placing any cleaning products in the USB port can be risky and you need to be very gentle. Apply pressure at the wrong angle and you may break or bend the connectors. If you’re worried about damaging the internal connectors, take your phone to a professional.

If you want to try it, you’ll need a toothpick or similar narrow object. You can buy phone cleaning tools online, but if you don’t have them on hand, a toothpick or the plastic end of an interdental stick will also work. We do not recommend using a safety pin or anything metallic, and you should never insert anything into a USB port.

With your poking tool of choice, very carefully begin working around the central electrical contact. Remember that the goal is to remove debris, not push it further in, so try to use small scooping motions. This should allow you to remove deeper dirt. Again, be gentle, and if you encounter resistance, change your movement instead of applying more pressure. Finally, blow out the USB port with compressed air to remove any loose particles.

How to prevent dirt from entering the USB-C port

Prevention is by far the best course of action. If you work in a dusty environment or regularly carry your phone in your pocket or purse, consider getting a dust cover kit or a phone case with built-in port covers. This will prevent dirt from getting into your USB port in the first place and you won’t have to clean it as often. Dust plugs can be easily lost, especially if you need to keep using the USB port for charging, but they are cheap and come in packs of several. If your phone supports wireless charging, you may want to consider some great wireless chargers in addition to using dust plugs.
