Causes of Damage

The main cause of damage to church ironwork is oxidation corrosion: a reaction with oxygen in the air causes rust to form.

Rusting is more likely when one or more of the following apply:

  • high moisture levels
  • high levels of salt in the air (e.g. seaside conditions)
  • high levels of pollution
  • damage to the paint or other protective coating

Over-cleaning of metallic objects can damage decorative elements made of softer metals, or destroy protective coatings such as galvanising.
