How to Clean Car Battery Terminals
Things Required 
  • Rubber Gloves
  • Stiff-bristled Brush
  • Screw Driver
  • Razor Blade
  • Electrical tape
  • Sodium Bicarbonate (Baking Soda) or Cola 
  • First, wear good quality rubber gloves to prevent any form of acid injury. Open the car hood and detach the battery terminals from the battery.
  • Now, with the help of a bristled brush, rub off the battery terminals. Make sure to clean the ring terminal, both inside out. Carefully scratch the inside of the ring terminal, with the help of a screwdriver or a pointed tool.
  • Once you clean the terminals to a clean and shiny state, examine the wires leading into the battery terminals.
  • In case you notice any form of greenish or whitish powder under the sheathing of the copper wire strands, cut open the wire housing, approximately ½ inch from the top, with a razor blade.
  • Keep cutting until you see shiny copper. Now, carefully cut any corroded wire you notice. Check that you leave enough length so that the wire easily reaches the terminal.
  • Next, use an electrical tape to stick down the wire. In case you fail to do so, you may need to get hold of a new cable.
  • Finally, make a solution of baking soda and water, and pour it over the terminals. You can also use a can of soda for the same. It will clean the gunk around the terminals and help them secure a better connection with the battery.
