Things You'll Need

Instructions

Alkaline Batteries

1

Fill a bowl with vinegar or lemon juice.
2

Dip a small, soft-bristled brush, cotton ball or cotton swab into the liquid.
3

Rub the liquid into the leaking battery or the remnants from a leaking battery. Continue cleaning until all of the residue is removed.

Acid Batteries

1

Fill a small bowl with baking soda.
2

Dip a cotton swab or small soft-bristled brush into the baking powder. Since it is powdery, it will fall off. This is OK. Do not add water or a liquid to the baking powder.
3

Rub the baking powder into the acid leak. As the powder is moved over the leak, it will absorb the acid and begin to form a paste-like substance. Use a clean soft cloth or cotton swab to remove the paste. Continue cleaning until all of the acid is absorbed.
