be kept tight and free of corrosion. A solution of two
tablespoons of baking soda to a pint of water makes an
excellent cleaning agent for corroded battery terminals
and a dirty battery case. Apply the solution with a paint
brush or whisk broom and thoroughly flush the outside
of the battery with clean water when finished. Coat the
battery terminals with a light grease or petroleum jelly to
inhibit corrosion.
CAUTION
Do not allow the soda solution to
enter the battery cells. It may cause
the battery to be neutralized.
