How to Clean Corroded Batteries From the Contact Point

Batteries, whether on a car, in a camper or in an electronic device tend to corrode when left in for a long period of time, especially if you do not use the battery for some time. It is common to see corrosion on an electronic device if you don't remove the batteries and you don't use that device often. Always remove batteries when not in use.

Instructions

1

Put the rubber gloves on -- battery acid is corrosive and will burn your skin, even if it is dry. Brush excess acid powder off the battery terminal. If you are working on a small device, use the old toothbrush. If you are working on a vehicle battery or some other large battery, use the bristle brush.

2

Pour some baking soda onto the corroded terminal. You only need enough to coat the terminal. For a large battery, pour just enough water onto the baking soda to wet it down. Allow it to soak for a few minutes. For batteries in electronic devices, wet the toothbrush, then brush the baking soda around. Take care to not let water get into the device.

3

Pour water onto a vehicle battery to rinse the baking soda and acid off the battery. Clean the terminals of baking soda and acid with a rag for batteries in electronic devices.

4

Repeat the procedure as necessary.
