It's best to first remove the terminals from the connections then scrub off the acid with a brass brush (from the dollar store) then pour water mixed with baking soda over the terminals (this will neutralize the battery acid) & scrub a bit more with the wire brush. Clean the inside & outside of the connections then rinse well by pouring water over the area. Your battery will be clean in no time.

* Be sure to clean off any of the acid, water & baking soda from your car. I failed to clean up the area right below my battery inside the hood area after doing this one time & the battery acid messed up my car by eating away at the metal.

---> PS. You can buy a batery terminal cleaner for about $3 at any Auto Part Store or Hardware Store. This is a round metal brush made to fit on to the terminal to clean it.

Coca Cola is excellent for cleaning battery terminals - just pour it on and the acid in it will eat up the corrosion. No joke! Good luck and God bless you.

Another one here with the Coca Cola as cleaner; once they're clean, keeping a copper penny on the battery( with a dab of caulk!) redirects the corrosion to the coin, not the terminals.

You can get a terminal head cleaner its good and don't take that long then you can get some little felt rings that has grease on them to stop the buildup coming back you can get them anywhere you buy a battery, and thanks I need to get me another Terminal cleaner.

Clean corrosion off the battery terminals, using a wire brush or steel wool, to scrape battery posts and cable clamps. Clean the top surface with a mild solution of baking soda and water, without letting it seep under cell caps.
