How To Clean Battery Terminals
The terminals of your car battery will have deposits which you need to scrub off. Since these are due to chemical reactions, you canât just wipe them off.
Vinegar contains acetic acid, which is not a very strong acid but can trigger the chemical reaction needed to get rid of corrosion and deposits. Disconnect the terminals with a wrench, and apply a mixture of baking soda and vinegar on the terminals. Let it sit for a while so the reaction can take place and loosen the deposits and dirt on the terminals.
Scrub it with a wire brush and clean it with water.
Another option is to use Coca Cola. Like vinegar, Coca Cola is an easily available option. Since it is a carbonated drink, it dissolves the metal oxides and gets rid of the rust on metals and alloys. There is also acid in the drink, which neutralizes the corrosion and cleans the terminals.
Again, first you need to disconnect the battery terminals or turn off the carâs ignition. First, scrape off the deposits as much as you can before you start with the coke. Once done, pour some of the drink on the terminals and leave it for about 10 minutes.
After a while, you will see that the coke has broken up the corrosion and deposits. Clean it with water and wipe it all off with a towel.
Make sure you dry the terminals and any metal parts after youâre cleaning them with water. If the terminals are left exposed to moisture, they can oxidize and begin to rust.

What Is Battery Acid Leakage
Battery acid is an alkaline residue composed of potassium hydroxide. While its not a true acid, its no less corrosive or hazardous. It can burn your skin, harm your eyes, and corrode the delicate wires and chips in battery-powered devices.
Youll only find this type of battery acid leakage with alkaline batteries. Devices increasingly are using lithium-ion batteries, and these batteries fail in a completely different way. While alkaline batteries emit a fluid that eventually turns into a white powdery crust, lithium-ion batteries abruptly stop working or they heat up, catch fire, or, in rare cases, explode.

Remove The Cables Working On The Negative One First
To be able to thoroughly clean the corrosion off of a car battery, you would need to remove the cables first with a wrench. But you must first identify the negative and positive terminals from where you are going to disconnect cables. For safety, the negative cable should be disconnected first to avoid electrocution and burns.
The negative terminal can usually be identified by a marking of the negative sign, the abbreviation NEG written on it, and/or the color black. The positive terminal comes with a marking of the positive sign, the abbreviation POS written on it, and/or the color red.
Also, while you disconnect the negative cable, you must try not to let the wrench contact the positive terminal. You might get shocked if they touch. Then move on to the positive cable after disconnecting the negative cable.
But if you are having a hard time removing any of the cables, try to twist the cable while pulling it up.
Clean Away Corrosion And Rinse
Using around a teaspoon of baking soda, or more as necessary, coat your battery terminals and other affected areas. Pour a small amount of water on each terminalthen use your brush to scrub the corrosion away. While a steel wire brush will work the best, an old toothbrush can work with enough elbow grease.
