Can you tell me how to clean car electrical connectors?

My car battery has white powder on the connectors. How do I clean car electrical connectors so I don't break down?

That’s definitely a good area to keep clean! There is a pretty simple process to follow for cleaning your car’s electrical connectors.
The first step is to disconnect the female battery cables with a wrench. Wipe it clean of dirt and corrosion with a clean cloth.
Then, use a small piece of fine-grit sandpaper to buff the metal connectors by wrapping it around the connectors and rotating until they are clean.
You can use vinegar to get rid of the corrosion and make sure the connectors are allowing for maximum power flow.
