What is the white, crusty substance accumulating on my S10 Blazer’s battery post?

The white, crusty stuff that can accumulate around S10 Blazer car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

How do I clean corrosion off my S10 Blazer vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your S10 Blazer’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
