Materials and Tools Needed:

  1. Safety gear (gloves, goggles, and a mask)
  2. Wrench or socket set
  3. A solution of baking soda and water (1/4 cup baking soda to 1 cup water)
  4. A small brush or old toothbrush
  5. A clean, lint-free cloth or paper towel
  6. Terminal protector spray or petroleum jelly
  7. Wire brush or battery post cleaner

Step-by-Step Guide:

  1. Safety first: Before you begin, make sure to wear safety gear, including gloves, goggles, and a mask, to protect yourself from any potential harm caused by battery acid or debris.
  2. Turn off the golf cart: Ensure that the golf cart is turned off and the key is removed from the ignition.
  3. Locate the battery: Open the battery compartment of your golf cart to expose the battery terminals.
  4. Disconnect the battery cables: Using a wrench or socket set, carefully loosen and remove the battery cables from the terminals, starting with the negative cable (usually black or marked with a “-“). Then, remove the positive cable (usually red or marked with a “+”). Keep the cables away from the terminals to avoid accidental contact.
  5. Prepare the cleaning solution: Mix 1/4 cup of baking soda with 1 cup of water to create a cleaning solution that will neutralize battery acid and help remove corrosion.
  6. Clean the terminals: Dip the small brush or old toothbrush into the cleaning solution and gently scrub the battery terminals and cable clamps to remove any dirt, corrosion, or debris. Be thorough and ensure that all areas are cleaned.
  7. Rinse and dry: Once the terminals and clamps are clean, use a clean, lint-free cloth or paper towel to wipe away any remaining cleaning solution and residue. Ensure that the terminals and clamps are completely dry before proceeding.
  8. Clean the battery posts: Use a wire brush or battery post cleaner to scrub the battery posts and remove any remaining corrosion or debris. Make sure to clean both the positive and negative posts thoroughly.
  9. Reconnect the battery cables: Attach the battery cables back onto the terminals, starting with the positive cable. Securely tighten the cable clamps using a wrench or socket set. Repeat this process for the negative cable.
  10. Apply terminal protection: To prevent future corrosion, apply a terminal protector spray or a thin layer of petroleum jelly on the terminals and cable clamps.
  11. Close the battery compartment: Once all steps are completed, close the battery compartment and ensure it is secure.
