Clean Car Battery Corrosion

Removing battery corrosion is a fairly simple and inexpensive task. Just follow these steps:

Disconnect the battery cables. Put on gloves to protect your hands first. When removing the battery cables from a vehicle that is more recent, you may be required to enter a security code into the navigation system.

First, disconnect the cable from the negative battery. The cable may be black or marked with a negative sign or the abbreviation NEG. Then, disconnect the red or positive cable. To free the cables, you may need pliers or a wrench.

Carefully examine the cables for any indications of excessive wear or peeling insulation. You will need to get new cables if your old ones are frayed or damaged.

Neutralize the corrosion. To neutralize the corrosion and begin removing it, use a battery cleaning spray or a paste made of baking soda and water. You may need to scrub the terminals with a wire brush if there is a lot of corrosion. After you’ve finished scrubbing, use water to wash it off.

Dry the battery. Use the microfiber cloth to dry the batteries, terminals, and cables once you’ve removed the corrosion.

Reconnect the battery cables. Connect the cables once the battery is dry. Take care not to tighten them too much. If you replaced your cables, you will connect the new ones at this time.

How Can You Prevent Battery Corrosion?

Here’s how to prevent battery corrosion:

Perform routine maintenance. Every so often, look for signs of corrosion on your battery. When you get your oil changed, you should do this. If you check your battery on a regular basis, you can catch any early signs of corrosion and deal with it before it gets worse.

Use a protective treatment. Commercial sprays or brush-on treatments for preventing corrosion can be purchased at auto parts stores. Before you use the battery cables, disconnect them to get between the cable and the terminal.

Make sure your battery is properly charges. Corrosion can result from either overcharging or undercharging your battery. Take your battery to a mechanic if it frequently overcharges or undercharges. They can figure out why.

Use petroleum jelly or battery greases. Corrosion can be prevented by coating the terminals with battery grease or petroleum jelly. Before applying either, remove the battery cables. Because it is silicone-based, battery grease will last longer in a hot engine.
