Technician A says a specially designed wire brush is available to clean the terminals of a side-terminal battery. Technician B says that baking soda and water can be used to neutralize corrosion on battery terminals. Which is right?

A specially designed wire brush is effective for cleaning the terminals of a side-terminal battery. These brushes are designed to reach the tight spaces around the battery terminals without causing damage to the terminal itself. This tool helps remove corrosion and buildup that can impede electrical connections, ensuring proper battery function.

Baking soda mixed with water is also an effective method for neutralizing corrosion on battery terminals. Corrosion typically forms on battery terminals due to the buildup of sulfuric acid from the battery. The alkaline properties of baking soda help neutralize this acidic corrosion, allowing for easier cleaning and improved conductivity once the terminals are cleaned.

Both techniques are useful in maintaining battery performance, making the combination of using a wire brush and a baking soda solution a comprehensive approach to battery maintenance. This understanding is essential for anyone involved in auto mechanics, highlighting the importance of keeping battery terminals clean for reliable vehicle operation.
