Remove The Cables Working On The Negative One First

How To Clean Car Battery Terminals

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.

    How To Clean Car Battery Terminals: The Complete Guide ...

    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.

    Step 1

    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.

    Step 2

    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.

    Step 3

    Step 4


    • One can or bottle of Coca Cola
    • Corroded car battery
