By coming into contact with oxygen, metals can change color, which is why their maintenance and cleaning is vital to protect and safeguard them.
In the case of copper, the corrosion process causes an unsightly brown patina. In the case of brass, on the other hand, dirt produces a black patina.
To avoid stains, simple natural tricks can be taken, allowing us to have copper and brass pots and pans and items so shiny that they look as good as new.
For light, recent stains, simply use warm water and soap. Mix the water with soap and use a sponge to clean the surface. Then dry thoroughly with a cotton or microfiber cloth.
Vinegar also helps to remove stains effectively. Pour a few drops in water and apply it to metals. Remember to dry thoroughly.
One of the most effective ways to clean copper and brass is by mixing lemon and salt. The acid in the lemon is an effective remedy for shallow stains.
To clean copper well, cut a lemon in half and rub it all over the surface. Afterwards, wipe well with a dry cloth.
To clean brass you can use a solution of water, vinegar, flour and salt. Apply it with a toothbrush and scrub well over the surface. Let it work for 10 minutes, then rinse with water and dry well.
