How To Clean Bronze

Bronze has a charming, warm glow that shines through when created into jewelry and household décor accessories like cabinet hardware, a bronze statue, candlesticks, and more that are all resistant to water damage.

Bronze develops a greenish patina over time, which is not surprising given that bronze is a copper alloy made up mainly copper at 88 percent and 12 percent tin.

While some people love the patina because it delivers a sense of antiquity, many prefer to restore bronze to its original shine, even if it’s only a few years old.

Fortunately, you don’t need any stinky or potentially caustic chemicals to clean and polish bronze; in fact, you can accomplish it with just a few common household materials.

  • Place a bowl with ketchup and your bronze object. The amount of ketchup you need to use will vary based on the size of the object you’re polishing.

The Polishing Process

While you’re rinsing the bronze, use your cleaning towel to wipe away any leftover polishing paste. Using a soft cloth, dry the bronze object. Allowing the bronze to remain wet will result in water stains.
