How to Remove Corrosion From Electronic Contacts
- 1). Remove the batteries if you need to remove corrosion on battery contacts. If cleaning other electronic contacts, disconnect power to the device to prevent a short circuit. Wipe as much of the corrosion away as possible with a clean cloth.
- 2). Dip a cotton swab into white vinegar. Brush vinegar directly onto the corroded contacts. Vinegar is a weak acid that will dissolve and loosen corrosion.
- 3). Wipe off the liquefied corrosion. Dry contacts completely before reinstalling fresh batteries.
- 4). Remove persistent corrosion by making a paste of two parts baking soda to one part water. Brush the paste onto the contacts with a cotton swab. Let paste dry.
- 5). Wipe away the paste. Spray compressed air on the contacts to dislodge any remaining corrosion. Wipe the contacts dry with paper towels.
