What should I do if my battery terminals are rusty?
To resolve the rusting problem, remove the Terminal from your battery as the steps below:
Newer model cars are different than older models so please contact Battery Australia and we will do the cleaning for you.
You will want to disconnect the negative terminal first, then the positive terminal.
You may need to use a pair of pliers to loosen and remove the cable/ wiring.
Be sure not to short your battery out by touching a metal tool to the battery and another metal object.
If you find that the cables are damaged or have excessive corrosion, replace them immediately.
If the battery terminals have damage, you will need to replace your battery.
You can now poor a little baking soda on each terminal/ post and the wiring connectors/clamps and scrub them with a wet toothbrush. If the toothbrush isn’t doing the trick, you can use a wire brush. When you have finished cleaning the terminals, wipe and dry the terminals with a lint free cloth.
Hook the positive wire back to the positive terminal/ post, then the negative wire back to the negative terminal/ post (reverse of what you did earlier).
