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. Instead of purchasing a commercial cleaner from the store, clean the bronze at home with natural ingredients to retain its sparkling appearance.

Things You'll Need

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

  • 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.

  • Dry off the bronze with a clean, soft cloth. If the bronze still appears dull, clean it with vinegar.

  • Combine an equal amount of flour and salt into a small bowl. Add 2 to 3 tbsps. of each for best results.

  • Slowly add vinegar to the dry ingredients until a thick paste forms.

  • Rub the paste onto the bronze pieces and allow to sit for 30 minutes.

  • Wash off the paste under running water. Dry the bronze with a soft cloth.
