Spray a small quantity of glass cleaner on your pair of diamond earrings and gently scrub away the grime. Try to focus on the inner, hidden portions of the earrings where the residue tends to accumulate. Use a toothpick to reach these hidden areas between the metal prongs and the diamond. After rinsing off, wash your earrings under an excess of tap water. Dry them with a soft cloth.
You can also use mild household chemicals, like ammonia, to cleanse off dirt from your diamond earrings. Mix ammonia in water in a 1 to 2 ratio, and soak the earrings in this concoction for 15 to 20 seconds. Take them out and scrub gently with a soft cloth. Use an abrasive cloth to dry the earrings off.
If you want to avoid ammonia, then use a mild dishwashing detergent. Mix a liquid or powdered dishwashing detergent, whichever is available, in water and soak the earrings in it for 10 minutes. Remove them from the mixture and scrub with a soft-bristled toothbrush to clean the diamonds and the metal and remove any traces of grime. Rinse the earrings off under tap water and pat them dry with a soft cloth.
Lest oil can also be used to clean the diamond jewellery. Soak your earrings in the oil for 15 to 20 seconds, cleanse them with a gentle brush and make them sparkle like new.
Mild abrasive cloth
If the grime accumulated is a bit intense, then use a mild abrasive cloth while you dry your diamond after using any of the above methods.
