PROBLEM: How to clean wall clock battery Terminals?

SOLUTION:
Take down the clock from wall and remove the batteries. Use a damp soft cotton swab to remove any major corrosion deposits. Wear vinyl gloves while cleaning any battery corrosion. Make your cleaning agent by combine 1 tablespoon of baking soda with a teaspoon or so of water. Stir to make a paste. Apply the baking soda paste to the battery connections using a cotton swab or small piece of cloth. Once the baking soda is applied, you may see it bubble and foam, as it reacts with the corrosion. When the foaming stops and there are no major deposits left to be scraped out. Rinse the connections by using just a little water applied with a cotton swab.
