You could also use quick-drying contact cleaner, which you can spray directly into your port. A flat, dust-free table or desk in a well-lit area.

You could try a cotton swab, but they are usually too thick to fit inside of a charging port.

If you’re cleaning the charging port of a PC laptop that has a DC power port instead of USB-C, use a flashlight to look inside the port first. Sometimes these ports have pins at their centers that can be easy to break. If you can’t fit a toothpick inside of the port without touching the pin, take your PC to a service center for cleaning instead.

To avoid damaging the port, don’t hold down the nozzle for more than 2 seconds. Too much air pressure can disrupt the phone or tablet’s delicate internal structures. Resist the urge to blow into the port with your mouth! This could add moisture to the port and potentially break your phone or tablet. [5] X Research source

Be gentle, but firm—just firm enough to remove stuck-on debris. If there is gunk inside of the port, you could dampen the cotton with a very small amount of rubbing alcohol and repeat the process.

If it’s difficult to get the remaining dirt out of the port, you could try wrapping double-sided tape around the end of a sewing or a syringe needle and gently nudging it free. If there is visible debris that you can’t remove using these methods, take your device to a service center. If you are still having trouble with your charging port, check your charging cable—it could be dirty or damaged. If you have another charging cable, give that one a try.
