There are many reasons that make your car difficult to start. One of them is due to the battery terminals have corroded. Let us see how to clean the battery terminals.
1. Clean with Baking Soda
– Step 1: Stop the car and turn off the engine. Make sure the car is completely turned off before you do any cleaning or battery replacement. Otherwise, you may experience shock or the battery will have a spark.
– Step 2: Determine the battery terminal size. 2 types:
- If the terminals are on the sides of the battery, you will need to use an 8 mm wrench to loosen the two nuts.
- If the terminal is on the side of the battery, you need to use a 10 mm or 13 mm spanner.
– Step 3: Remove the battery terminals.
- Loosen the nut on the cable clip at the negative terminal (-). Remove this cable completely from the battery pile. Remember to remove the negative terminal of the battery first.
- Repeat the above steps with the cable clamp at the positive (+) end. If you are having trouble removing any of the cables, try rotating and pulling them at the same time.
– Step 4: Check the battery. Check if the battery is cracked, leading to a possible acid leak. If any signs are found, replace the battery.
– Step 5: Check the battery piles, clamps. Check the battery connectors, the stakes, the cables to see if they are in the best condition. If large cracks are found, replace them.
– Step 6: Prepare a cleaning solution. Stir 1 teaspoon of baking soda (about 15 ml) into 1 glass of water (about 250 ml). Dip an old toothbrush in this mixture and scrub the tip of the battery to remove rust, corrosion. You can even immerse the ends of the battery cables in hot water to remove corrosion on them.
– Step 7: Scrub the battery. Use a toothbrush to clean the clamps and stakes of the battery. Make sure you soak the brush in the baking soda solution well enough.
– Step 8: Rinse the battery again. Wash the battery and cables with cold water. Make sure all baking soda and rust are washed off. Dry the battery and the clamps with a clean cloth.
– Step 9: Battery lubrication. Lubricate all exposed metal surfaces on the battery poles, poles and clamps. Use commercially sold battery terminal protection lubricants or sprayers. This helps to push water out of the contact surface, protecting electrical equipment from getting wet, short-circuiting, and increasing electrical contact for the battery head.
– Step 10: Replace the battery.
- In contrast to disassembling, we attach the positive (+) cable clip to the suitable pole first. Use a spanner to tighten the nut.
- Do the same with the negative clamp (-). Check the strength of the poles by gently rotating them with your hand.
2. Clean with coca
– Step 1: Prepare. Wear a plastic glove to protect yourself from electrodes. Prepare a suitable spanner to loosen the battery terminal nuts.
– Step 2: Remove the battery. Use a loosen spanner each terminal. Do not remove the cables completely.
– Step 3: Use coca to clean the battery pole. Pour coca onto one end of the battery. Note pouring from the inside out in one direction. Do this on top of the other battery.
– Step 4: Wash off with water. Let the coca soak for 2 minutes, then rinse with water, dry. Next, you just need to tighten the stakes and start the car.
