To keep your gold jewelry looking shiny, you could use a toothbrush and some soapy water to clean inside the crevices of the jewelry. Dishwashing liquid is a suitable cleaning solution for cleaning gold jewelry. Make sure that you rinse the jewelry with warm water until the water runs clear to ensure that all of the soap has been rinsed off completely. Afterwards, buff your jewelry piece with a soft, lint free cloth.
Instead of using soap and water to clean your gold jewelry, you could also use a non-abrasive jewelry cleaner. Before using a particular jewelry cleaner, check to see if the jewelry cleaner is safe to use on your jewelry especially if it contains gemstones.
Try not to wear your gold jewelry everyday to avoid getting it damaged. If you do need to wear your jewelry on a daily basis, then it's recommended that you clean your jewelry everyday to avoid any build-up of grease and dirt.
Store your gold jewelry in a velvet-lined jewelry box or case that contains compartments for each item. If you don't have a jewelry box, you should wrap each piece of jewelry in a separate piece of tissue paper and keep them in a small bag or pouch. It's best to keep your jewelry separate because this will prevent your gold jewelry from getting scratched by other jewelry pieces that may contain gemstones.
When storing your jewelry, make sure that it's dry because moisture can cause the springs and clasps to weaken over time.
