Jewelry cleaning is the process of removing dirt, oils, and tarnish from various types of jewelry, including gold, silver, and gemstone pieces. Regular cleaning helps maintain the shine and appearance of jewelry, ensuring it looks its best. Common methods include using mild soap and water, specialized jewelry cleaners, or ultrasonic cleaners, depending on the material and type of jewelry. It is important to consider the specific care requirements for different materials. For instance, pearls and opals may require gentler cleaning methods, while diamond and platinum can withstand more robust cleaning techniques. Always check for any loose stones before cleaning to avoid damage.
