Solution

1. Preparation

Gather all necessary tools and materials.
Ensure the vehicle is parked on a level surface, and the power is turned off.
Wear safety gloves and goggles for protection.

2. Disconnect the Battery

Use a socket wrench to loosen the negative (-) terminal first; remove the cable and secure it away from the battery.
Loosen the positive (+) terminal next; remove the cable and secure it away from the battery.

3. Clean the Terminals

Mix a solution of baking soda and water (1 tablespoon of baking soda in 1 cup of water).
Dip an old toothbrush or battery terminal cleaner brush into the solution.
Scrub the battery terminals and connectors gently to remove corrosion.
For stubborn corrosion, let the solution sit for a few minutes before scrubbing.
Wipe the terminals with a clean, dry cloth to remove any residue.

4. Reconnect the Battery

Reattach the positive (+) terminal first and tighten it securely.
Reattach the negative (-) terminal next and tighten it securely.

5. Final Check

Inspect the terminals once more to ensure everything is tight and clean.
Close the battery compartment and ensure all covers are properly replaced.
