The type of cleaning that is necessary and acceptable depends on the type of jewelry. If it is costume jewelry (such as nickle or other inexpensive metals), you will want to stick with soap and water. If it is silver, you can try a good silver polish. For gold, there is a different type of polish. Most stores have these types of polishes in the cleaning isle or near the jewelry counter. Jewelry that contains precious or semi-precious stones will require greater care. Some stones, like sapphires, are too soft to clean with polishes or the type of jewelry cleaner that asks you to soak the item in a tray of chemicals. For home remedies, you can try vinegar, mix water and baking soda to make a paste polish, or tooth paste. Again, be extra careful if you are cleaning jewelry that contains stones. The hardest part to clean will be under the stones or in any gaps between links. I found the most helpful thing was to use a clean tooth brush with whatever cleaning agent you chose.
