Solution

1. Preparation

Tools Required: Safety goggles, gloves, wrench set, wire brush or terminal cleaner, baking soda, water, clean cloth.
Wear safety goggles and gloves to protect against acid exposure.

2. Disconnect Battery

Use a wrench to loosen the negative (-) terminal first and remove it.
Then, loosen the positive (+) terminal and remove it.

3. Clean Terminals

Mix a solution of baking soda and water (1 tablespoon of baking soda per cup of water).
Dip the wire brush or terminal cleaner into the solution and scrub the corroded areas on the battery terminals and cable connectors to remove corrosion.
Rinse the terminals with clean water and dry them with a clean cloth.

4. Inspect and Repair Cables

Check battery cables for any signs of damage or fraying. If cables are damaged, replace them.
Ensure the cable connectors are not loose or corroded; if necessary, replace them.

5. Reconnect Battery

Start by connecting the positive (+) terminal first and tightening it.
Then, connect the negative (-) terminal and tighten it securely.

6. Final Check

Inspect that both terminals are tight and free from corrosion.
Ensure that there is no debris or dirt around the battery area.
