  • What is the white, crusty stuff around my Outback’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Outback car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • What do I do about corrosion on my Outback car battery? To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag.
