1. Prepare a solution with soap and water. Squeeze some detergent in the bowl, then pour in warm water and stir the solution to make it foam. Use a soft cleaner, preferably a natural one, to avoid the chemical composition of the cleaner damaging the ring. You can also use mild hand sanitizer, shampoo or shower gel. Make sure not to use soap containing "humectant", or you may leave a film on the ring.

2. Put the ring in the bowl 15 minutes. Soak the ring in soapy water. Soap water will penetrate and disintegrate the dust, dirt and stains on the ring.

3. Take out the ring for inspection. If you can still see the stains, you need to clean them further. Instead, you can wash the ring with water.

4. Gently brush off the dust on the ring with a soft toothbrush. Be sure to use a brush with soft bristles, not a brush with medium hardness or very hard bristles, so that your ring will not be scratched. Brush gently, and use a brush to clean the dust in the small gap. If necessary, you can use toothpicks to help clean up the dust in the gap.

5. Wash the ring with cold water.

6. Dry the ring. Put the ring on a paper towel or a clean cloth and let it dry completely.
