How to Remove Bronze Tarnish and Pitting

Kaye Wagner

Bronze tarnishes when it becomes exposed to oxygen, water or any other material that will corrode it. Metal becomes pitted when it corrodes for a long time and actually develops small holes in its surface. Extensive pitting will completely ruin a piece of bronze metal beyond repair. If bronze has light pitting or tarnish, you can salvage it by using a homemade cleaning solution.
