How to Clean and Polish Bronze. Almost everyone has bronze décor pieces in their home. These metal artifacts may have looked shiny and new when you bought them, but the longer they are exposed to air and moisture, the greener and duller they become. Bronze reacts with moisture (oxidation) to form a greenish layer on its surface, called patina. Some homeowners appreciate the darkened finish because it adds character to the metal, but many prefer their bronze clean and shiny. Here are a couple of natural ways to clean and polish your bronze treasures.
How to Use Lemon
Step 1
Gather the bronze items you want to clean. Clean only a few pieces at a time because the task requires a good amount of elbow grease.

Step 2
Pour a tablespoon of baking soda into a small dish and squeeze some lemon juice over it. The pasty mixture will bubble, but will quickly settle down.
Step 3
Use a small piece of soft cloth to rub this paste onto your bronze piece. Rub until you're satisfied with the clean. You can leave the mixture on the item while you work on the other pieces.
Step 4
Wash the mixture off under running water, then dry and buff with a clean soft cloth.
How to Use Vinegar
Step 1
Combine equal amounts of flour and salt in a small dish, then add enough vinegar to make a paste.
Step 2
Smear the paste onto the bronze pieces and let stand for about 30 minutes.
Step 3
Wash the paste off under running water, then dry and buff with a clean soft cloth.
