How to Clean Battery Corrosion


If you’re wondering how to clean battery corrosion, you’ve come to the right place. This common problem can be removed safely and efficiently with some baking soda, vinegar, and water. Once you’ve removed the corrosion, you can confidently continue using battery-powered items. Of course, keeping your batteries clean and corrosion-free is also essential for safety reasons.

Baking soda

There are several ways to clean battery corrosion, and one of them is using baking soda. Combined with hot water, baking soda cleans the battery terminals and other affected areas. A steel wire brush is the best tool for the job, but an old toothbrush will do, too. You can make a cleaning solution of baking soda and water and use it to scrub the terminals. You can also use the same cleaning solution for battery cables.

Using the baking soda solution to clean battery corrosion is easy. You can apply it directly to the corroded area or apply it slowly over the area. Once you’ve finished, use a damp paper towel to remove any excess. Next, rinse the battery and the cable end with cool water.


It can quickly become corroded if you ignore your car battery. This can reduce the power your battery can produce and its lifespan. The corrosion usually occurs at the battery’s terminals, but careful cleaning can help eliminate it. Unfortunately, vinegar can also damage touch screens, so you’ll need to use caution when cleaning with it.

To clean your battery’s terminals, first place the battery in a basin with a few ounces of water. Then, fill the basin with about 350 ml of vinegar. Immerse the battery terminals in the vinegar solution for about 30 minutes, then wipe them down with a clean cloth.


You can clean battery corrosion with water or a homemade cleaning solution. Both of these solutions are acidic, but they work to clean out corrosion in various ways. One of the essential cleaning methods involves mixing baking soda with water. This mixture is effective because it causes a chemical reaction that loosens the corrosion. Soak the corroded clamp in the solution, and leave it there for 20 minutes.

You can also use baking soda and water to clean battery terminals. For best results, use a steel wire brush. If you don’t have one, you can use a stiff-bristled toothbrush. First, mix the two ingredients in a clean plastic container. Then, dip the brush in the solution and scrub the terminals.

Socket wrench

A socket wrench is an excellent tool to clean battery corrosion. Before you start cleaning, you should ensure that the battery is disconnected from the vehicle. Doing so will prevent power spikes and help remove corrosion from the battery terminals. You need to loosen the clamps on the positive and negative battery terminals to clean battery terminals. To do this, you will need a ratchet and socket wrench.

The battery terminal clamps are held in place by an 8 to 13-millimeter nut. Some cars even feature a “pinch” system to tighten the clamp without tools. To remove the clamps, use a socket wrench and a ratchet with a matching socket. When removing clamps, wear gloves to protect your hands from the acid. It can burn your fingertips and sensitive skin.

Acidic solution

Battery corrosion can be a severe problem. Fortunately, cleaning it is pretty straightforward. You can use household items like baking soda and vinegar to neutralize the acid. Make sure to wear gloves and safety glasses when handling the battery. Also, you should check your battery for leaks regularly. If you notice any, it’s best to clean the battery immediately.

First, you should turn off your device and remove the battery. If the corrosion is crystalline, you should use a Q-tip to wipe it away. If there is still some residue left, use a toothpick to pick it out.
