How can i dry my charger port iPhone 12

Howdy tahnaeah,

It sounds like you are seeing a liquid-detection alert on your iPhone. We know how important having a working iPhone is for you, and you’re in the right place to find a resolution.

We can see you are coming over to the Communities from the most relevant article that can help address your question: If you see a liquid-detection alert on your iPhone. As quoted directly from that article,

"If your iPhone or Lightning accessory is wet

Unplug all cables or accessories. Don't plug them in again until they're completely dry.

To dry your iPhone:

1. Tap your iPhone gently against your hand with the Lightning connector facing down to remove excess liquid. Leave your iPhone in a dry area with some airflow. 
2. After at least 30 minutes, try charging with a Lightning cable or connecting a Lightning accessory.
3. If you see the alert again, there is still liquid in the Lightning port or under the pins of your Lightning cable. Leave your iPhone in a dry area with some airflow for up to a day. You can try again to charge or connect a Lightning accessory throughout this period. It might take up to 24 hours to fully dry.

Here are a few things not to do:

• Don’t dry your iPhone using an external heat source or compressed air.
• Don't insert a foreign object, such as a cotton swab or a paper towel, into the Lightning connector.
• Don’t put your iPhone in a bag of rice. Doing so could allow small particles of rice to damage your iPhone."

If the alert remains after taking those steps, your iPhone may benefit from an in-person inspection at your local Apple Store or Apple Authorized Service Provider: Apple - Find Locations - Location Selector. You'll need to contact the store to confirm hours or operation and to make an appointment prior to visiting. Otherwise, you can reach out to Apple Support directly as well, to confirm your options: Get Support
