Bronze bars are a popular medium in the arts industry. Aside from the metal’s classic beauty, bronze provides superior strength and casting properties that enable artists to sculpt and create intricate pieces.
Even brass masterpieces are prone to darkening, though. When exposed to air and moisture over time, bronze develops a greenish, darkening buildup called patina. Fortunately, there are ways to remove the patina to restore a bronze statue’s sheen.
Baking Soda and Lemon Juice
Mix two tablespoons of baking soda with a spot of lemon juice until a soft paste develops. Rinse the item in warm water and dry completely to remove airborne particles or other debris. Then, apply the paste to the item with a small polishing cloth.
Leave the paste on the surface for 20-30 minutes before rinsing it in warm water. Buff dry the surface with a clean towel and see if the sheen has returned. If not, repeat each step until you achieve the desired result.
Vinegar, Flour, and Salt
Alternatively, you can use vinegar, flour and salt to restore the shimmer of bronze. Simply combine equal parts of flour and salt, then add a few drops of white vinegar. Mix it until a soft paste with the consistency of toothpaste forms.
Bronze bars are essential to creating a sculpture, which will only maintain its beauty if you know how to maintain it. Following this guide will preserve your art and reward your hard work.
