If you have a battery that won’t hold a charge, or if the battery terminals are dirty, you can clean them with coke. This is an old-fashioned cleaning method that works well on metal surfaces.

  1. Pour about 1/2 cup of coke into a small bowl or container.
  2. Wet your hands and scrub the terminals clean with the coke. Be sure to get into all the nooks and crannies.
  3. Rinse off the terminals with water and dry them off with a paper towel. ..
