How to Clean the Ports on your Electronic Device

Difficulty

Easy

Steps

Time Required

10 - 15 minutes

Introduction

Use this guide to clean the ports on your favorite electronic device.

If your device isn't registering something being plugged into a port, like a USB flash drive, that port may be dirty and require cleaning.

The cleaning procedures for each type of port follow the same progression: cleaning with air, a brush, and finally a cotton swab with isopropyl alcohol. Although similar, the procedures do vary slightly, and you should read the steps for the type of port you're cleaning.

This guide uses tools that you might have around the house, but we also sell a Precision Cleaning Kit that includes some small brushes and picks to make your cleaning life easier.

Tools

Step 1

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

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

Don't use your mouth to blow into your audio 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 end 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.

Step 6

Don't use any metal tools to clean the audio port, as you risk damaging it.
Insert the head of a brush, like a dry toothbrush, into the audio 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.

Step 7

Apply a few drops of highly-concentrated isopropyl alcohol (>90%) to the cotton.
Insert your tool in the audio port.
Don't force the tool into the port, as you risk damaging the contacts.
Twist the tool back and forth within the port to clean it.
Wait a few minutes for the isopropyl alcohol to evaporate before plugging in your device and testing it.

Step 8

Don't use your mouth to blow into your USB-A 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 end 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.

Step 9

Don't use any metal tools to clean the USB-A port, as you risk damaging it.
Insert the head of a brush, like a dry toothbrush, into the port.

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.

Wait a few minutes for the isopropyl alcohol to evaporate before plugging in your device and testing it.

Step 11

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

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.
