Clean an alkaline battery leak by removing the batteries and swabbing the area with a cotton swab dipped in vinegar. Wear safety glasses and latex gloves when cleaning up the battery leak, as contact with potassium hydroxide in the battery can lead to skin and eye irritation.
- Put on protective gear
Put on a pair of safety glasses to protect your eyes from contact with the potassium hydroxide in the battery, and slip on a pair of latex gloves to protect your skin from the chemical.
- Remove the batteries
Open the battery compartment, and remove the batteries. Dispose of the batteries carefully to avoid contact with the corrosion. Flush the skin or eyes with water if contact occurs.
- Clean with the cotton swab
Dampen a cotton swab with white vinegar. Rub the corroded areas with the cotton swab, allowing the acidic vinegar to dissolve the alkaline corrosion. Make sure to clean all surfaces that have come into contact with the corrosive material, getting into the grooves with the cotton swab. Reapply vinegar as the cotton swab dries.
- Dry the area
Once all the corrosive material is removed, use a clean cotton swab to dry all the surfaces in the battery compartment.
