How To Clean Your Battery Terminals

 

You spend timing cleaning your vehicle. Washing, waxing, and vacuuming.  

How about checking under the hood?  

Using materials you have at home I will show you 5 easy steps to clean your battery terminals which can help your car battery last longer and be stronger. 

Items you will need: 


Protective gloves 

Baking Soda 

Water 

Rag 

Tooth Brush (One you will never use again) 

Petroleum Jelly 


A Battery Terminal Cleaner Brush is also a helpful tool!


Homemade battery cleaner is 1 Spoonful of baking soda in one cup of water. Mix together. 

Make sure your engine is off. Vehicle unlocked. Access your battery which may be under the hood or in the trunk.  

Visually inspect your battery for any signs of leaking, swelling or bloating of the case. If you see any of these signs you should stop and replace the battery.  

Next check your battery terminals. Are they corroded? If they are they should be cleaned. Disconnect the Negative (Black) side first and the Positive (Red) side last.  

Clean the terminals: 

Using the toothbrush and your cleaning solution scrub the build-up off the battery terminals. Dip the toothbrush into the cleaner and use some elbow grease to get the job done.  

Next rinse the battery with water and wipe down the battery with a rag. Then wipe the vehicle side terminal connections with a rag.  

Apply a small amount of petroleum jelly to the connection and re-attach the positive cable first and the negative cable last. Make sure to tighten the connections. A loose connection can create arcing, a voltage drop which is resistance in the circuit, and damage to the connection and wiring. I have seen the battery connection and wiring melt due to the heat generated from the resistance in the circuit from a loose connection.
