Luckily, there are a couple of simple ways how to clean car battery corrosion. The first, and most proven, method is to use baking soda. Combine a teaspoon of baking soda with a glass of water, and then use a brush to scrub the battery terminals with the mixture.
This method works by neutralizing acidic corrosion and will leave your battery terminals smelling great.
Disconnect your battery cables
The first step in cleaning your blue stuff on car battery is to disconnect the battery cables and connect them to the terminals. You can do this by using distilled water or a cleaning solution. Use a wire brush to remove corrosion from the terminals.
Next, wipe the battery terminals with a lint-free cloth. After rinsing the battery, rub petroleum jelly around each terminal. Make sure to connect the positive cable first, then the negative cable, and finally reconnect the battery cables. Car battery usually have a life span of five years, and it is normal to see some corrosion in them when they are reaching the end of their life. Clean the corrosion off of your battery using common household items.
If you have a new car battery, you may need to enter a security code to remove the battery cable. Otherwise, you can use a terminal cleaner to loosen the connection. If the terminal clamp is damaged, the clamp may break and fall off the battery post.
Check the damage battery cables
Before clean car battery corrosion, you must check the battery cables. If the cable is corroded, it will decrease the available voltage at ignition. You must ensure that the negative battery cable is intact as a direct connection to the negative terminal can result in sparks and ignite hydrogen gas from the blue stuff on car battery. In addition, damaged battery cables will lead to a stalled car. Check the battery cables regularly and replace them if necessary.
If you notice a white or brown substance on the terminal end of the battery cable, it is an early sign of corrosion. Corrosion results from the buildup of deposits caused by leakage of the electrolyte and the reaction with other elements. If you notice these signs, you should immediately replace the battery cable or consider getting it replaced. You must also check for cracks, breaks, or corrosion along the cables.
Remove the corrosion from battery terminals
You can remove the corrosion from battery terminals by cleaning them with a solution made of baking soda and water. A steel wire brush works best, but an old toothbrush will work just as well. To get the job done, mix the baking soda with water and scrubbing the battery terminals should be a simple process.
Clean battery cables with battery corrosion spray, you can use the same method. To avoid contaminating the terminals, you should wear protective gloves and paper towels. After cleaning, you should rinse them with clean water and dry them. You can also apply a little petroleum jelly on the battery terminals to prevent further corrosion. This will also make the connection stronger.
Make sure you don’t use too much petroleum jelly, because it will cause a poor connection. Lastly, clean the battery terminals again with a rag before reconnecting them. Remember to clean the terminals thoroughly before using petroleum jelly or any other cleaning solution.
Rinse and dry
Fortunately, there are many DIY methods for blue stuff on car battery corrosion that you can try. First, you need to get rid of all corrosion and dirt on the battery terminals. Make sure you protect your battery post area with a terminal protector pad, which are thin circular pads that are red or black in color. These pads contain a protective coating that can effectively neutralize corrosion. Rinse thoroughly after each cleaning and dry the battery completely.
Next, you need to disconnect the negative and positive blue stuff on car battery cables. The negative cable will be marked with a (-) sign, and the positive cable will be marked with a (+) sign. You may have to wriggle the connectors loose, however, if the corrosion is severe. When the battery is disconnected, make sure to remove the cable if it is attached to the car. After that, you can safely re-connect the battery to the car’s electrical system.
Reconnect your battery to your vehicle
Disconnect the cables that connect the battery to your vehicle. This will help prevent electrocution and burns. To identify the cables, find the positive and negative terminals on your battery.
The negative terminal is marked with a negative sign, while the positive terminal is typically marked with a positive sign, abbreviated POS, and red in color. If you are not sure which cable is the positive one, you can check the connector for wear and damage by using a socket wrench.
Before reconnecting your battery to your vehicle, apply some petroleum jelly on the terminals. This will help prevent corrosion and keep them lubricated. If you don’t have petroleum jelly, you can use a cheaper option. When reconnection is complete, remember to put the junction covers on your vehicle. Otherwise, your vehicle may require professional help. But, it’s still possible to clean blue stuff on car battery corrosion by yourself.
It is a good idea to clean a battery leak using a mild household acid such as vinegar. Both liquids can neutralize alkaline discharge. You can apply a drop of lemon juice or vinegar to the area that is corroded. Wait for it to neutralize.
Use about a teaspoon of baking soda to coat the battery terminals and any other areas that are affected. Use your brush to remove the corrosion. A steel wire brush is the best option, but an old toothbrush will do just as well with some elbow grease.
