A typical car battery consists of individual cells, with each compartment alternating between lead and lead plates coated with lead dioxide immersed in a sulfuric acid solution. This causes a chemical reaction that releases electrons that provide the juice that turns the starter motor, turns on the radio and keeps the lights on, among other functions.
Sometimes, especially on cheap batteries, the sealant around the post allows the sulfate in the battery to escape and react with the lead in the post, producing a white deposit and flakes. If it is heavy, it will interfere with the battery connection and block the flow of electricity, leaving you stranded.
Fortunately, this is one of the easiest areas of your vehicle to maintain. Here are some simple methods to clean corrosion from car battery terminals.
Mix them to make a consistency of pancake batter and apply to the terminal. The mixture will slowly remove the corrosion.
Reasons For Battery Terminal Corrosion & How To Prevent It
Even if it works, it’s a mess. I remember my dad doing this trick on my sister’s Ford Pinto in the 1980s. By the way, my dad rarely swears, but my vocabulary grows a little every time he has to come up with a bad excuse for a car.
You can achieve the same effect by using any brand of cola. Its weak acidity will slowly dissolve the corrosion on the battery terminals. Pour a little on the terminal, leave it for a few minutes and then wipe it clean.
I have about three of them scattered around the garage. One reason I like them is because they are like me – cheap but effective.
Just disconnect the battery, start with the negative terminal. Use a brush to loosen and remove deposits and corrosion from terminals and connectors.
How To Remove Car Battery Corrosion: Causes & Prevention
Apply battery terminal grease to the terminals to prevent corrosion. It can be found at any auto parts store and usually comes in small packets like ketchup.
Another great option is AMSOIL Heavy-Duty Metal Protector. It creates a protective coating on the terminals that prevents corrosion. In addition, you can use it as a base for vehicles to protect it from rust.
Regardless of your method, replace the hood periodically and clean the battery terminals as needed. Living in cold places is normal, I clean the battery terminals every fall no matter what it looks like to make sure I don’t run into a dead engine when I turn the key on a cold morning. You’ve probably come across a white-blue substance on your battery terminals at least once before opening the hood of your car.
Car batteries are important for the trouble-free operation of your car. It controls electrical consumers such as ignition, lights, radio or AC. Having a parking space in the middle of the road can be embarrassing for many. So, what causes battery terminal corrosion?
Why Do Battery Terminals Corrode? ❤️
The most common cause of battery terminal corrosion is hydrogen or electrolyte leakage from the battery. It may also be because the dynamo easily charges the car battery over a long period of time. Chemical reactions with copper clamps are also not uncommon.
Corrosion of the battery terminals occurs after years of driving with the same battery, and you need to understand the cause and how to fix it. Here is a more detailed list of the five most common causes of battery terminal corrosion.
Batteries convert acid into electrical current. Sometimes the hydrogen gas in the battery leaks out and finds its way into the atmosphere. It reacts with other substances, and corrosion of the battery terminals is the result.
Different battery-related problems will appear depending on which part of the battery corrosion has formed. If it is on the negative pole, this is a sign of undercharging. If it is on the positive terminal, it is caused by overcharging.

This problem is synonymous with lead batteries. Due to age or damage, the battery electrolyte can leak and accumulate on the battery terminals. The likelihood of electrolyte leakage increases if you overfill the battery with water.
Copper is a good conductor and does not corrode easily. However, when an electric current passes through the copper terminals, copper sulphate is produced and this leads to corrosion of the battery terminals.
A blue precipitate on the copper terminal may indicate copper sulfate. Copper sulphate does not conduct electricity well and you start the car.
If the alternator undercharges the car battery, it can cause corrosion of the car battery terminals. Check the voltage with a multimeter when your car is running to make sure it doesn’t charge above 14.5 volts when you start the engine.

It can also happen because you regularly charge the car battery with a car battery charger.
If you overcharge the car battery, it can cause the electrolyte to leak, as mentioned earlier. Not all car batteries are rechargeable, but you should double check if you have one that it is not overcharged.
Now that we know what causes car battery erosion, we need to know how to fix it. There are several different methods you can use to clean the battery terminals.
If you want to remove copper sulfate from the terminal, you need a solution of soda and water, and a brush. First, check that the car’s ignition is switched off. Remove the battery terminals and use the brush to remove some of the corrosion.
Serious 12v Battery Corrosion. Normal?
Apply the baking soda solution and continue to remove the corrosion with the brush. When finished, clean the terminal with clean water. It is a good idea to apply a wheel bearing grease to the terminals to prevent further damage. Some may prefer Vaseline, but this does not last as long as grease.
Most of the soft drinks we use contain a small amount of carbonation. Pour some baking soda on the terminal and use a soft sponge to remove the residue. This works well in the absence of a soda solution.
If the battery has excessive corrosion on the terminals, use a solution of baking soda and an old toothbrush. Begin by removing the battery terminals – negative should be first. Mix the baking soda solution and put it in a cup. Soak each terminal in the solution and let it soak for the next 20 minutes.
Rub a caustic substance on the terminal. Pour the soda solution and make a fresh one. Soak the battery terminals again while removing the corrosive material. Clean the terminal with water and let it dry or wipe it with a damp cloth. You can also use sandpaper to clean the terminals. Apply some grease or petroleum jelly and reattach the terminals, starting with the positive.
The Importance Of Keeping Car Battery Connections Clean
The best way to prevent corrosion of the battery terminals is to ensure that the alternator does not overload the car battery. You also want a newer car battery in good condition. Anti-corrosive sprays are also effective in preventing corrosion.
Since a leaking car battery causes a lot of battery wear, you may need to replace your car battery to prevent it from happening again soon.
This clamp is one of the best on the market and will help prevent further corrosion of the battery terminals. The clamp is made of thin copper and keeps the entire clamp in contact with the electrical current.
One of the causes of battery terminal erosion is an over- or under-charged battery. The manufacturer’s manual often has a recommended battery voltage. Be careful not to charge it too hard with the car charger.

Also check the voltage when the car is idling with a multimeter. If the alternator charges above 14.5 volts, there is a problem.
Various sprays are available on the market to prevent terminal corrosion. You can also use vaseline or grease if you think the spray is expensive. A coated felt pad can also be used to prevent corrosion of the battery terminals. If you have opened the hood of the car and a green/white fungus grows on the poles of the car battery, this is a sign of corrosion. Battery corrosion can be caused by many different issues and can cause various problems for your car, including a significant reduction in the life of your car battery.
