Grab your cleaning brush and with its stiff bristles, brush away the white/green corrosive parts as much as you can. Use scraper if some spots are stubborn. After you’ve done brushing make a mixture of water and baking soda. The ratio should be 1 TBSP baking soda to 1 pint of water. Now, gently fill the irrigation bulb, turkey baster, with the mixture you made.

After that, slowly apply the mixture to the cable terminals and cable connections. If ever there are areas that are heavily corroded, you can use your bristled-cleaner tool to further scrub the spots. You might as well disconnect the cable clamps and terminals to clean it more efficiently. You must disconnect the negative side first and then the positive side. It is recommended that you use battery cable removal tools to ensure proper disconnection of cables.

Use your battery cable brush to remove corrosion found in terminals, battery posts, and hold down clamps and brackets. Use the baking soda mixture to flush these parts clean. Then, use a liquid cleaner in a spray bottle to wash the outside of the battery including the cable ends and the hold down parts. A sponge or rag can be used to get rid of any remaining dirt or grease. When you are done cleaning, dry the battery with a cloth.

After cleaning and drying is done, carefully put back together and tighten up the clamps properly around the battery terminals. Make sure to start with the positive cable first when you reconnect the battery. You have done one car maintenance task and make sure to check on the car battery often. Having regular maintenance will make your car perform better during cold winter months.
