Fixing a corroded battery terminal is not easy. You should clean it thoroughly to make it function again. A solvent and a sturdy scrubbing tool are vital for this purpose. You can use an old toothbrush or a wire brush and a battery cleaner. The following ways can assist you in fixing corrosion from the terminals. In cold temperatures, DO check that the battery’s fluids are still liquid. If they’ve frozen solid, don’t jump-start the vehicle—that could cause the battery to explode! DON'T connect the black cable to the negative terminal, as that could also cause an explosion. ALWAYS follow the instructions in your owner’s manual. We need to neutralize the acid on top of the batteries first and foremost. This can easily be done with a homemade mixture of baking soda and water.

Using the wire brush, neutralize the battery acid with a baking soda/ water solution. Or buy a can of battery terminal spray cleaner. Dry off the battery with paper towels. Then apply acid neutralizing felt pads (about $3 a set) to the posts and connect the cleaned terminals (Photo 4). Finish the job by coating each terminal with anti-corrosive Remove the battery negative terminal clamp and then the positive terminal clamp. Apply a mixture of one ounce of baking soda and four ounces of water to the terminals and clamps. Let it stand for 10 minutes. Rinse it off and then brush the surfaces with a wire brush (available at any auto parts store). Since most car batteries are fairly accessible, regularly inspecting and dealing with corrosion isn’t a difficult automotive maintenance task. How Can You Clean The Corrosion? The simplest way to clean battery corrosion is with a wire brush. Remove the connections from each terminal and brush each clamp and terminal until the gunk has been .
