Simple Tips for Removing Car Battery Corrosion

Are you frustrated with the corrosion on your car battery? Do you feel like it's a huge pain to maintain and keep clean? It doesn't have to be. This blog post will give you some guides for removing corrosion from your car battery. This can help prevent power losses and ensure that your vehicle runs smoothly!

If your car battery corrode, it will make the battery not work. The corrosion will make the car not start in the morning when you work. It can also cause damage to other things in your car like the AC and electrical wiring.

Usually, you can see car battery corrosion. It is easy to spot. Sometimes, people have an older battery, and the corrosion will start to grow around the terminals or cables of your car's battery. This reduces how well it conducts electricity, making the battery not work as well and sometimes stop working altogether.

Keeping your battery's corrosion-free extends its life and performance. But there's no need to be concerned! Battery rust removal is straightforward, and it may be done by anybody.

Yes, and you are not the exception.

You can get rid of battery corrosion by doing these 6 simple steps.

Step 1

Unplug Your Battery Cables

If you want to avoid getting shocked when disconnecting your car battery, make sure you disconnect the negative cable first.

There are two sorts of wires that can be distinguished by their appearance. A negative cable is indicated by the (-) sign, the abbreviation 'NEG,' and the color black. A positive cable is indicated by the (+) sign, the acronym 'POS,' and the color red.

Step 2

Check for damage to the battery cables.

Damaged and worn battery cables are bad for cars. If the cables are showing signs of corrosion or are frayed, splintered, peeled, or dried out in any way, then it is time to replace them with new ones.

Step 3

Remove corrosion from the battery and terminal connections.

After the wires have been removed, the battery corrosion can be removed and neutralized. There are a couple various approaches to this, so we'll go over them.

  • Apply a battery cleaning solution where corrosion has formed on the battery and battery cables. Commercial-grade cleansers can be used to clean your battery. The battery will be cleaned and the acid will be neutralized. If it is not available, baking soda or Coca-Cola can be substituted. Coca-Cola is recommended by several individuals as a simple and inexpensive solution to clean their car engine. But you should be careful because Coca-Cola has unhealthy sugars and acids that can damage your engine.
  • On the other hand, the baking soda technique is tried and true as well as easy to execute.  What you have to do is add a teaspoon of baking soda and a glass of water. Use an old toothbrush or bristle brush to scrub the solution on the corroded areas. To fix a corroded battery, cover it with baking soda. Then pour water on the terminals. The two things will react and neutralize the acid corrosion. If you need to, do it again on the ends of the cables.

Step 4

Remove the detergent and rinse with clean water. After putting the acid on the rust, use a toothbrush or a bristled brush to scrub off the rust.

Be careful to avoid the solution nor the corrosive elements fall on other parts of your car. If you can take your car's battery out, then do that.

Be careful when you use professional-grade supplies. Do not let the battery cleaning chemicals touch your car if you use them. The chemicals can stain your car permanently if they come in contact with it.

Once you've washed off all the corrosion, rinse the battery and cable end. Let them dry. If you can, use an air compressor. It will make things go faster.

Step 5

Take Some Corrosion-Preventative Measures  Apply anti-corrosion pads once everything dries. These protect your battery posts. Use pads that are coated in a battery-corrosion preventative compound.

If your car battery is wet, use petroleum jelly on the terminals. This will make it easier for electricity to go from the terminal to the cable end. It will also help protect your battery terminals from future corrosion.

Make sure that you use anti-corrosion pads around your battery posts. These protect the battery from corrosion.

Step 6

Connect Your Battery to Your Vehicle. After you clear the corrosion, let everything dry. Then you can put a substance on your battery that will keep it from rusting again.

Connect the positive battery terminal first. Then connect the negative one. Do this in REVERSE order to avoid complications.

Now, if you want to apply some extra battery-corrosion protector, do it!

Do you want to skip Steps 1 through 6? Keeping your car battery clean is important. It will last a long time and work well if you do.

You can do this job yourself, but if you want, you can also bring your vehicle to the nearest mechanical shop near you.
