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.
Locate And Disconnect The Battery
With the car turned off, pop the hood and find the battery. Don your safety glasses and gloves: the white residue on your battery terminals is dried battery acid, which isnt something you want to mess around with.
Use a socket wrench to disconnect the battery, starting with the negative terminal. This terminal should be labeled with a negative sign and may have a black cap. Loosen the bolt and carefully remove the cable from the terminal.
Disconnect the positive terminal secondthis one should be labeled with a positive sign and may have a red cap. Once you remove the positive connecter, dont let it touch the negative connector or any other metal part in the car.

If youve ever gotten in your car, turned the key to start the ignition and nothing happened, chances are pretty good that it was a battery problem. Maybe you left the lights on and it drained your battery, or maybe there was something more to it, like dirty, greasy, corroded battery terminals.
This problem pops up more often than you might think, especially if you leave your car sitting without running for extended periods of time. You see, when the engine doesnt run, and it just sits, the battery terminals oxidize at a rapid rate. In order to combat this, you should start checking your battery terminals, regularly, for build-up and corrosion. If this happens, your battery posts will appear to be covered in a white, ashy substance. Fortunately, these are easy to clean and something that you can do entirely yourself.
What Youll Need
Before you jump under the hood, lay out all of your tools and cleaning supplies. These include:
- Locking pliers or vice grips

How To Clean A Corroded Car Battery With Coca Cola
Corrosion on a battery is a problem that often occurs with older batteries. The battery fluid leaks out causing the metal to fuse with other parts of the battery. This is a problem when the battery needs work or replacement. There is no need to take the car to a mechanic to fix this problem. A simple solution of Coca Cola will remove most battery corrosion.
Disconnect the battery cables if possible before beginning. Remove the negative side first, then the positive side. If you remove the positive side first, then you may get shocked because the current remains connected to the car. Tie back both cables so they are out of the way. This prevents them from moving out of place and accidentally touching the battery causing electric shock. If you can’t remove the cables because of corrosion, then pour a small amount of Coke around the connection points, taking care not to touch any part of the battery. Once the Coke has eaten the corrosion, then you can remove the cables.
Pour a small amount of Coca Cola over any corroded areas slowly. Add more Coke later if you need to increase the corrosion power. Wait for the Coke to bubble and eat away at the rust and corrosion. Wait for the Coke to stop bubbling before you move on to the next step. This should take about a minute. Pour some Coke over the battery connectors themselves if there is any corrosion present on them.
