When exposed to oxygen, metals can change color, which is why their care and cleaning is essential for protection and preservation.

With copper, the corrosion process creates an unsightly brown patina. However, with brass, dirt creates a black patina.

To avoid stains, simple natural measures can be taken that allow us to make copper and brass pots and objects shiny so that they look like new.

For light and fresh stains, simply use warm water and soap. Mix water with soap and clean the surface with a sponge. Then dry well with a cotton or microfiber cloth.

Vinegar also helps to effectively remove stains. Add a few drops to water and apply to metals. Remember to dry well.

One of the most effective ways to clean copper and brass is by mixing lemon and salt. Citric acid is an effective remedy for superficial stains.

To clean copper well, cut a lemon in half and rub it all over the surface. Then clean well with a dry cloth.

To clean brass, you can use a solution based on water, vinegar, flour and salt. Apply it with a toothbrush and rub it well on the surface. Leave on for 10 minutes, then rinse with water and dry well.
