Baking Soda (Bicarbonate of Soda) can be used to neutralize battery acid corrosion on cars, mowers, etc. , because it is a mild alkali. Be sure to disconnect the battery terminals before cleaning. Make a paste of 3 parts Baking Soda to 1 part water, apply with a damp cloth to scrub corrosion from the battery terminal. After cleaning and re-connecting the terminals, wipe them with petroleum jelly to prevent future corrosion. Please be careful when working around a battery--they contain a strong acid.
You can also use Coke or Pepsi to clean the posts on your car battery. Simply pour on and it will clean them almost like magic.
If you inadvertently spill battery acid on any of your clothing then you could risk holes appearing in your clothes. Wash any clothes that have been affected in a strong solution of baking soda and water. The solution will neutralize the acid preventing damage.
