How to Clean Battery Terminals

You maintain the appearance of your car by washing, waxing, and vacuuming it. But have you ever thought of cleaning things up under the hood of your car? Cleaning your battery terminals might really help your automobile battery function better by allowing it to breathe easier.


  • Gloves that provide protection, such as dish gloves
  • Baking soda is a type of baking soda.
  • Water
  • A shabby toothbrush
  • Rag
  • Petroleum jelly is a type of jelly that is used to lubricate surfaces.
  • Combine the ingredients

One tablespoon of baking soda should be added to one cup of water, and the mixture should be properly mixed.

  • Disconnect the battery from the cables

Engine and battery performance can be adversely affected by accumulation of debris, corrosion of the battery, and accumulation of filth on its terminals. If you discover that the battery case is leaking, bulging, or bloated, you should forgo the cleaning and instead visit your local Firestone Complete Auto Care for a new battery replacement.

  • Dip a toothbrush into your cleaner and start scrubbing

Start by washing the terminals with just an old toothbrush which has been dipped in your baking soda cleaner. This will require a little elbow grease, and you’ll need to clean the toothbrush on a regular basis as you go about your tasks. To completely remove any remaining accumulation, properly clean the terminals. Keep the toothbrush out of the bathroom and away from the children.

  • Wash out the residue with water and lay it out to dry

You should give the battery a quick washing after removing all the rust and debris from the terminals. To clean the terminals, keep filling a spray bottle with water and spray them down. It’s also possible to clean everything using a wet rag if you will not have a spray bottle on hand. Next, dry the terminals fully with a second rag, if necessary.

  • Rub petroleum jelly onto the terminals

This will lubricate them, aid in the prevention of additional corrosion, and assist in the strengthening of the connection. It is easy to get things moving again when the car didn’t bother or if the battery flow is low by keeping your car batteries in good condition. It is critical to keep a constant charge in your battery to avoid becoming stranded on the road.

How to Clean Corrosion from a Car Battery

3. Submerge and soak the battery terminals in the vinegar solution that has been made

Lift the terminal clamps and submerge them in the jar of vinegar until they are completely submerged.

4. Wait a few minutes

After that, remove the terminals out of the vinegar and wipe them down with a clean towel or rag one more time. Make sure you get rid of any muck that has accumulated. Using another towel or rag, lightly spray it with water for a quick rinse.
