Problem with battery post corrosion you clean them but problem reoccurs and your car wont start until posts recleaned Is there a product to prevent corrosion or is this a symptom of another problem?

There is a product that looks like flat washers made of felt that you can fit over the battery posts that will prevent corrosion (don't remember what it's called, but available at your local auto aprts store or Walmart). You can also try putting a dab of grease on the battery posts and terminals after cleaning.

The grease will work best for you to help eliminate corrosion's. The point of putting grease on the terminals is to keep oxygen from coming in contact with the terminals and also help with keeping acid off the posts. When you clean the terminals use baking soda and water to neutralize the acid which will help for future corrosion
