One of the easiest ways to clean a diamond ring at home is using a solution of lukewarm water and liquid detergent. Make sure the liquid soap you are using to clean your diamond rings is mild and appropriate for the gemstones and metal settings. Else, it can corrode the metal and even stain the diamonds.
Start the cleaning process by putting your wedding diamond ring in the cleaning solution and leaving it for a while. After 20 minutes, take it out and gently scrub the dirt off using a soft bristled brush. Finally, rinse the ring thoroughly using normal water.
