Phone charging port
One of the most-asked cleaning questions there is, and the manufacturer's guidance does not answer it — while prohibiting the tool every article recommends.
Precautions
- Disconnect from the power supply first
- Check the manufacturer's instructions
- Consider professional help
In detail
A charging port fills with pocket lint, and a phone that stops charging is usually a phone whose port is packed rather than broken. It is one of the most-asked cleaning questions there is, and it is worth being clear about what the evidence does and does not support. The phone manufacturer's cleaning guidance covers the GLASS, CERAMIC AND METAL surfaces of the device. It does not address the port at all. What it does say bears on it directly and negatively: DO NOT USE COMPRESSED AIR, and do not let moisture get into any opening. Compressed air is the technique almost every consumer article recommends for exactly this job. So there is a prohibition and no method. Consumer sources suggest a wooden or plastic pick, a soft brush, or a toothpick, and warn against metal tools near the contacts — advice that is plausible but has no authority behind it.
