How to clean an iPhone charging port (Lightning or USB-C)

Step by step: how to clean an iphone charging port

Safety first. Turn the iPhone off and unplug the cable first. Never put metal into the port (paper clips, pins or a SIM tool), because the contacts are fragile and metal can short them. If the phone shows a liquid-detection alert, dry it as Apple describes instead of cleaning.

1. 1

   Turn the phone off and take off the case

   Unplug the cable and turn the iPhone off. Remove the case, since a thick or dirty case can stop the cable seating fully and look like a port problem.

2. 2

   Look inside with a light

   Shine a flashlight straight into the port. Lint usually sits as a gray or dark mat packed against the back wall. If you can see bent or damaged contacts, stop and contact Apple.

3. 3

   Sweep the port with a dry, soft brush

   Brush gently in and out of the opening with a clean, dry, soft-bristled brush, then tap the phone, port down, against your palm. Loose dust and pocket fluff should fall out.

4. 4

   Ease out packed lint with a toothpick

   If a mat of lint remains, slide a wooden or plastic toothpick along the back wall of the port and lift the lint out toward you. Work slowly with light pressure and stay off the contacts. Packed lint often comes out in one flat piece.

5. 5

   Check again with the light

   Look inside again. You should see the back wall of the port clearly. Repeat the brush and toothpick steps until nothing is left.

6. 6

   Plug in firmly and test

   Turn the phone on and push the cable in firmly. It should click in fully, with no gap. Apple’s charging steps say to remove debris and then plug in firmly, and to check the cable and adapter for damage if it still will not charge.

What not to put in an iPhone charging port

Leave out anything metal, anything wet and compressed air. These are the common shortcuts that turn a five minute fix into a repair.

Cleaning a Lightning port vs a USB-C port

The best way to clean an iPhone charging port is the same for both types: dry brush first, then a non-metal toothpick, then a firm test. The shape of the port changes where you put the toothpick.

• Lightning (iPhone 14 and earlier): the port is a flat slot with contacts along the inside. Run the toothpick along the back wall and lift lint out; do not scrape the sides.
• USB-C (iPhone 15 and later, most Android phones): the port has a thin center tongue carrying the contacts. Work the toothpick in the gap around the tongue, never levering against it, because it can bend or snap. Clean a USB-C port on an iPad or laptop the same way, with the device off.
• Other Apple gear works the same way. For the AirPods case, Apple says to use a clean, dry, soft-bristled brush and not to put anything else into the charging port.

For an Android phone, check your maker’s guidance too; most give the same warnings about metal tools and liquid.

What to do if your iPhone says liquid is detected

Dry the phone, do not clean the port. Apple’s liquid-detection guide says to tap the iPhone gently against your hand with the connector facing down, then leave it somewhere dry with some airflow, and try charging again after at least 30 minutes.

• It can take up to 24 hours to dry fully; you can try again through that time.
• Do not use a hair dryer or other heat source, or compressed air.
• Do not push a cotton swab or paper towel into the connector.
• Do not put the phone in rice; Apple says small rice particles can damage it.

If charging still fails after the port is clean and dry, see Apple’s won’t-charge checklist, which covers cables, adapters and outlets. If the sound is muffled as well, our iPhone speaker guide uses the same dry tools.

Mistakes to avoid

• Using a paper clip, safety pin or SIM ejector tool in the port.
• Blasting compressed air into the port, which Apple says not to use on an iPhone.
• Cleaning the port while the phone is on or plugged in.
• Prying against the center tongue of a USB-C port.
• Drying a wet port with heat or rice instead of air and time.
