What must be done if further cleaning is needed for a charging port?

Using a few drops of alcohol to clean the charging port is an effective method because isopropyl alcohol (commonly known as rubbing alcohol) acts as a solvent that can dissolve dirt, grime, and corrosion without causing damage to electronic components. It also evaporates quickly, which helps to minimize the amount of moisture present once the cleaning is done, reducing the risk of further damage to the internal components.

This approach ensures that the cleaning process is safe and effective, especially since the charger port contains sensitive electronic contacts. Allowing the alcohol to sit for a brief period helps to loosen stubborn debris, making it easier to remove.

In contrast, using water is risky because water can cause short circuits and corrosion within electronic devices. A vacuum cleaner may not effectively target the dirt directly inside the port and could potentially damage delicate parts. Moreover, putting the port in rice is a myth that is not useful for cleaning; while rice can absorb moisture, it does not address dirt and debris inside the port itself.
