2005 Mercury Montego Question: Battery terminal corrosion

Postive battery terminal corrosion cleaned month ago. Corrosion returning. Why? -
Answer 1
The battery probably has a small leak, possibly around the battery terminal. I would consider replacing the battery. Also, when you clean a battery, clean the entire battery with an acid neutralizer (baking soda) and remove both terminals and clean the posts and the cable ends. -
