How to Clean Bronze Metal

Once air and moisture encounter bronze, it begins to appear dull and a green layer begins to form on the surface. While some people like this dark appearance, others prefer to keep the bronze shiny and clean.

Keep bronze clean and polished with common household items.

Things You Will Need

  • 1 tbsp. baking soda
  • Small bowls
  • Lemon juice
  • Clean, soft cloths
  • Flour
  • Salt
  • Vinegar

Once air and moisture encounter bronze, it begins to appear dull and a green layer begins to form on the surface.  While some people like this dark appearance, others prefer to keep the bronze shiny and clean. Instead of purchasing a commercial cleaner from the store, clean the bronze at home with natural ingredients to retain its sparkling appearance. 

  1. Add 1 tbsp. of baking soda to a small bowl. Squeeze an equal amount of lemon juice over the baking soda and stir until a paste forms.
  2. Rub the paste onto the bronze with a clean cloth. Leave the mixture on the bronze for two to three hours, then remove it by running warm water over the bronze.
  3. Dry off the bronze with a clean, soft cloth. If the bronze still appears dull, clean it with vinegar.
  4. Combine an equal amount of flour and salt into a small bowl. Add 2 to 3 tbsps. of each for best results.
  5. Slowly add vinegar to the dry ingredients until a thick paste forms.
  6. Rub the paste onto the bronze pieces and allow to sit for 30 minutes.
  7. Wash off the paste under running water. Dry the bronze with a soft cloth.
