Steps to Clean Corroded Battery Connections
Step 1: Turn Off The Power
First, turn off the power to your device or vehicle. This can be done by removing the key or unplugging the device. Always ensure everything is off. This keeps you safe while you work.
Step 2: Inspect The Battery
Next, look at the battery connections. Check for any corrosion. If you see white or blue powder, you have corrosion. Remember, do not touch it yet!
Step 3: Prepare The Cleaning Solution
To make a cleaning solution, mix baking soda and water. Use one tablespoon of baking soda for every cup of water. Stir it well. This will help break down the corrosion.
Step 4: Remove The Battery Cables
Now, use a wrench or pliers to remove the battery cables. Always remove the negative cable first. This is usually black. Then remove the positive cable, which is usually red. Be careful not to touch both cables at the same time.
Step 5: Apply The Cleaning Solution
Take your old toothbrush and dip it in the cleaning solution. Gently scrub the corroded areas. The baking soda will fizz a little. This is normal. Keep scrubbing until you see the metal again.
Step 6: Rinse The Battery Connections
Once you are done scrubbing, rinse the connections with clean water. Use a clean cloth to wipe away any leftover baking soda. Make sure everything is dry before you reconnect the battery cables.
Step 7: Reconnect The Battery Cables
Now, it’s time to reconnect the battery cables. First, connect the positive cable. Then connect the negative cable. Make sure they are tight and secure.
Step 8: Test Your Device
Finally, turn on your device or vehicle. Check if it works properly. If everything is good, you have done a great job!
