Bronze flatware – eating and serving utensils made of a copper alloy with or without nickel-plating or other finish -- comes in plain designs as well as decorative designs that may require additional cleaning. Additionally, bronze flatware has copper in it, which can stain and corrode. As a result, the methods used to clean it differ slightly from other metal flatware such as stainless steel.
Wash your bronze flatware immediately after you use it with warm soapy water and a cloth. Rinse it thoroughly and then wipe it dry with a soft cloth.
Apply a homemade bronze cleaning paste to the flatware to remove the stains or a commercial bronze flatware-cleaning product. To make your own paste, pour 1/2 cup vinegar into a container, add 1/2 tsp. salt and sprinkle flour into the container while mixing with a spoon until the contents of the container have a paste-like consistency.
Apply the paste, or commercial cleaner, to the flatware and wait 20 minutes. If you're using a commercial product, wait for as long as recommended on the product label.
Wipe the paste or commercial cleaner from the flatware. Rinse the flatware thoroughly with warm running water. Dry and polish your flatware with soft cloths.
