How do you clean car battery corrosion?

My car battery has been having some issues, how do I clean up the corrosion around it?

Oh no, battery corrosion can be really shocking when you first see it! Let’s get it cleaned up as fast as possible. Before you get started, you’ll need:
  • Baking soda
  • Water
  • A cup
  • Paper towels
  • Scrub sponge
When you have those items, follow these steps:
  • First, disconnect the battery from your car. As you’ll be using a bit of water, you don’t want to risk an electrical shock or other damage.
  • Then, spread baking soda over the entire area that’s affected by the corrosion. Baking soda should work to neutralize the battery acid.
  • Now, add a small amount of water to the baking soda. This should cause a chemical reaction that will hopefully remove the corrosion.
  • Next, dry the area with paper towels.
  • Finally, clean off the area and potential remaining residue using a scrub sponge.
While this should take care of your battery issues, it never hurts to have a backup plan. If you’re looking for towing coverage, lockout service, tire change, jump starts, key replacement, and more, try a roadside assistance membership through Jerry.
