Module 6. Materials & hardware

Which of these is a common cause of corrosion?

  • Water in fuel.
  • Spilled battery acid.
  • Untreated metal.

Explanation

Spilled battery electrolyte is a classic direct cause of corrosion because the strong acid attacks metal and surrounding structure aggressively and immediately. Untreated metal and water in fuel may eventually contribute to corrosion, but spilled battery acid is the recognised common, active cause requiring prompt neutralising and cleanup.

chevychase asking:

surely they are all common causes of corrosion?
