How to Clean Alkaline Battery Leakage From Terminals
- 1). Verify that the battery is an alkaline-type battery. Acid-type batteries also contain electrolyte fluids, but they are acid. You should use an acid to clean leakage from alkaline battery terminals, but acid batteries require an alkaline cleaner. Reversing the two may make a worse mess and can be hazardous (for acid-type batteries, you can follow this same procedure except use baking soda, which is alkaline).
- 2). Follow safety rules. Potassium hydroxide can cause respiratory damage, skin irritation and eye injuries. Work in a properly ventilated space. Always wear gloves and eye protection when cleaning leakage from alkaline battery terminals.
- 3). Remove the leakage from electrical contacts and other surfaces using vinegar or lemon juice applied with a small brush, such as an old toothbrush. Do not use water. Water will not neutralize the alkaline and may damage electronic circuitry.
- 4). Allow the cleaned area to dry, and then wipe the surfaces and contacts with a barely damp cloth. Set the device in a dry place for several hours so it will dry completely before installing new batteries.
