When it comes to battery maintenance, it’s important to make sure the battery terminals are free from corrosion. Corrosion can prevent the battery from functioning properly and even cause damage to other parts of the vehicle. In this article, we’ll go through the steps on how to clean battery corrosion.
What is Battery Corrosion?
Battery corrosion is the build-up of a white or bluish-green substance on the terminals of a battery. This substance is a result of the chemical reaction between the battery acid and the metal terminals. Over time, the corrosion can become so severe that it can prevent the battery from functioning properly.
Before starting, you’ll need a few materials:
- Baking soda
- A wire brush or toothbrush
- A wrench or pliers
- A cleaning cloth
Steps to Clean Battery Corrosion
Step 1: Disconnect the Battery
The first step is to disconnect the battery. Use a wrench or pliers to loosen and remove the negative cable from the battery terminal. The negative cable is usually black and has a minus sign (-) on it. Then, remove the positive cable, which is usually red and has a plus sign (+) on it.
Step 2: Mix Baking Soda and Water
Mix baking soda and water together to form a paste. Use about 3 tablespoons of baking soda for every 1 tablespoon of water. The paste should be thick enough to stick to the terminals.
Step 3: Apply the Paste
Apply the baking soda paste onto the battery terminals. Use a wire brush or toothbrush to scrub the terminals until the corrosion is removed. Be sure to wear gloves and eye protection.
Step 4: Rinse with Water
Rinse the battery terminals with water to remove any leftover baking soda paste. Use a cleaning cloth to dry the terminals.
Step 5: Reconnect the Battery
Reconnect the battery by first attaching the positive cable, then the negative cable. Tighten the cables with a wrench or pliers.
What causes battery corrosion?
Battery corrosion is caused by the chemical reaction between the battery acid and the metal terminals. Over time, this reaction can build up a white or bluish-green substance on the terminals.
Can I use something other than baking soda to clean battery corrosion?
While baking soda is the most commonly used substance to clean battery corrosion, other household items such as vinegar or lemon juice can also work. However, be sure to rinse the terminals thoroughly with water after using any substance.
How often should I clean my battery terminals?
It’s recommended to clean your battery terminals every 6 months to prevent corrosion build-up.
Cleaning battery corrosion is an important part of battery maintenance. By following these simple steps, you can ensure your battery terminals are free from corrosion and functioning properly. Remember to always wear gloves and eye protection, and to rinse the terminals thoroughly with water after cleaning.
