To clean enamel jewelry I would use something non abrasive and safe on all types of fine jewelry. A solution created by mixing half Mr. Clean and water then a small amount of ammonia should work great. This is the same solution used in the ultrasonics of many jewelry stores I know of and is safe with all types of jewelry. Even the easily damaged opals can be cleaned in this solution. Allow your jewelry to soak for 15 seconds then rinse with water and dry.
