How to Clean the Ports on your Electronic Device

步骤 1 Inspect your ports




• Shine a flashlight into your port and inspect it for any large blockages.
• A buildup of dust, grime, and lint inside the port can prevent the connector from fitting properly in the port.
• Follow the links below to skip to the procedure for your type of port:
• USB-C port
• Audio port or "headphone jack"
• USB-A port
• HDMI port
• Laptop "barrel" charging port

步骤 2 Blow air into the USB-C port


在这个步骤中使用的工具：
Dust Blower
$4.99
购买


• 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.
• If your device still doesn't work or sits properly after multiple repetitions, move to the next step.

步骤 3 Brush your USB-C port
• Don't use any metal tools to clean the USB-C port, as you risk damaging it.
• Insert the head of a brush, like a dry toothbrush, into the port, making sure the hairs surround the middle contact pad (the black tab in the middle of the port).
• Gently turn the brush in small circles to break up any clumped debris.
• Remove the brush and use a dust blower or compressed air to blow out any debris.
• If any debris is stuck, reinsert the brush and rotate it to let the hairs "scoop" out any debris.
• Plug in your device and check if it's working. If it's still not working, move on to the next step.

步骤 4 Clean the USB-C port with isopropyl alcohol
• Follow this guide to make a custom cotton swab.
• You can also use dental picks with barbed tips (non-flavored).
• You can use a normal cotton swab, but most are too thick and have loose cotton that can snag on sharp edges.
• Apply a few drops of highly-concentrated isopropyl alcohol (>90%) to the cotton.
• Insert your tool between the middle contact pad and the perimeter of the USB-C port itself.
• Don't force the tool into the port, as you risk breaking the middle contact pad.
• Slide the tool along the perimeter of the port to clean it.
• Wait a few minutes for the isopropyl alcohol to evaporate before plugging in your device and testing it.
