Provides a one-step solution to battery terminal corrosion removal and acid neutralization. Delivers a powerful, heavy-duty foam that clings to battery surfaces, provides extended contact time and neutralizes acid quickly. Helps eliminate power leaks and aids in restoring full starting power. Features a low odor, non-flammable, water-soluble formula. Contains a unique color indicator that turns red in the presence of acid, then changes back to yellow when the acid is neutralized. Leaves behind a residual film that provides short term corrosion resistance.
