Though gold does not tarnish like sterling silver, it can still collect dirt after regular use, which will dullen its surface and deter its prevalent glow.
To clean your gold jewelry at home, it is important to use a mild soap and a soft cloth or brush, as gold can easily scratch.
You will need a solution of dishwashing liquid and warm water, a soft bristled brush, a small bowl, and a soft dry cloth. In the small bowl, place the gold piece then cover it with the warm water and soap solution. Allow the piece to soak for at least 15 minutes. Then, use your brush and scrub the piece gently, concentrating on all visible dirt. Rinse under warm water and wipe dry with the soft cloth.
