How to Clean Car Battery Corrosion

Have you ever lifted the hood of your Nissan and noticed there was corrosion around the battery? Corrosion isn’t pretty, but you can easily clean and maintain your car battery and save yourself from the high cost of a new battery. Follow along with this guide at Baytown Nissan to learn what causes car battery corrosion and how to remove corrosion from your car battery. 

Signs of Battery Corrosion

Baytown drivers can see signs of battery corrosion if they start experiencing weaker power, trouble starting their car, or low voltage codes displayed on their dashboard. Drivers can quickly perform a visual inspection by popping the hood after the vehicle has been fully cooled or hasn’t been used for at least 30 minutes. If the battery terminal is caked in white, or sometimes green/blue, powdery material, that means it may be time to remove the corrosion from the car battery. Drivers should also note if they see signs of damage or rust on the metal parts of the terminals and cables.

Causes of Car Battery Corrosion

What causes car battery corrosion? Busy drivers around La Porte may notice that time is the main cause of the corrosion on their battery. When a vehicle is constantly heating and cooling as the motor runs, it causes the release of hydrogen gases through ventilation. Over time, the gases are let-off and mix with the surrounding material and leave a substance at the connection point. The corrorison drivers can see as a result is because of the electric connection happening at the terminal of a car battery.

Removing Corrosion from a Car Battery

DIY enthusiasts around Liberty who are interested in learning how to clean car battery corrosion can use two main options. Auto parts stores sell solutions made specifically for cleaning car batteries, or drivers can create their own homemade solutions. Other tools needed are wire brush or scrub sponge, gloves, goggles, and a respirator when handling the solution or creating a homemade solution for protection, and when working around battery acid, electric currents, and rust. 

Professional Battery Cleaner

With a battery cleaning solution or other electrical contact cleaning spray, liberally cover the affected surface of the battery, then brush with a wire brush until the corrosion is removed.

DIY Battery Cleaning Solution

Those using a DIY cleaning solution need first remove the connectors from the terminal. Pour the baking soda over the corrosion to neutralize the acids, then add water to start the reaction. Dry the area with a paper towel and rub the affected area with a scrub sponge.

To prevent further corrosion, use a rust inhibitor spray, a battery protector spray, or an anti-corrosion gel. Is it time to replace the battery? Learn how to test a car battery.
