How to clean battery terminals from oxidation?

Oxidation of battery terminals is a common problem faced by car owners. The build-up on the terminals impairs contact, which can lead to problems with starting the engine and the operation of electrical equipment. In this article, we will tell you how to effectively and safely clean the terminals of your car from oxidation. You can also improve your car and transform it using tuning accessories, a wide range of which is available in our product catalog.

Why do terminals oxidize?

Oxidation is a natural chemical process caused by the reaction of metal with oxygen and other substances present in the environment. In the case of a battery, acid vapors released from the electrolyte settle on the terminals and react with the metal, forming a coating.

Signs of oxidation:

• White, blue or greenish coating on the terminals.
• Difficult engine starting.
• Unstable operation of the car's electrical equipment.

How to clean battery terminals?

There are several ways to clean oxidized terminals:

1. Baking soda solution:
• Remove the terminals from the battery (first the negative, then the positive).
• Prepare a solution of 1 tablespoon of baking soda and 1 cup of water.
• Apply the solution to the terminals using a brush (toothbrush or metal).
• Rinse the terminals thoroughly with clean water and wipe dry.
2. Special cleaners: Car shops sell special cleaners for cleaning battery terminals. They effectively remove oxidation and prevent it from recurring.
3. Mechanical cleaning: To remove heavy deposits, you can use fine-grit sandpaper or a wire brush. Be careful not to damage the terminals.

Precautions:

• Before starting work, be sure to disconnect the terminals from the battery.
• Use protective gloves and goggles.
• Do not allow the soda solution or cleaner to come into contact with your skin or eyes.

Oxidation prevention:

• Regularly check the condition of the battery terminals.
• Lubricate the terminals with special grease or technical petroleum jelly.
• Monitor the condition of the battery and eliminate electrolyte leaks in a timely manner.

Cleaning oxidized terminals is a simple procedure that you can do yourself. Regular battery care will ensure its reliable operation and extend its service life.
