    • Don't use your mouth to blow into your USB-C port, as the moisture from your breath can damage the contacts.

    • Insert the tip of a dust blower, or the nozzle of compressed air, at one corner of the port.

    • This gives room for any debris to eject out of the port.

    • Blow a few puffs of air into the port.

    • Plug in your device to check if it works and if the connector is fully seated.

    • If your device isn't working or seats properly, unplug it and repeat the blowing process.

This comes at a time where my Galaxy S9 thinks the port is broken so often I've changed to my old phone and gotten a wireless charger. Might as well give it a proper deep clean some day.
