Our advice is to not wait any length of time to clean your engagement ring. It can be kept clean very simply if you brush it with a tooth brush often. Make sure to brush underneath the main diamond when you want to clean your ring. Once some dirt, oils, and buildup has taken place underneath the diamonds for a length of time then it is much harder to clean your diamond ring. If you start almost immediately after receiving your ring then it is much easier to keep it shining.
