ame you are a genius when it comes to cleaning rings!!!! I did exactly what you told me.... A few drops of method (I bought the blue one) in a plastic dish filled with hot water. Soaked both my engagement ring and my anniversary wedding band in this dish on opposite sides to avoid scratching. I think I soaked them for five to ten minutes. Wasn't sure how long to soak. Removed one, brushed it, rinsed under hot water and OMG!!!!! The white gold rhodium plating is PURE SHINY BRIGHT WHITE/SILVER!!!! I haven't seen it this white since DH gave it to me last month!!!! And the diamonds!!!! OMG!!! My main stone is a marquise D color and it used to sparkle regardless... But now I think it lights up a room!!!! My side stones are both baguettes and princess cut in both rings, channel set. WOW!! My rings look gorgeous!! I wish I knew about using dish soap last month! I hope the red conosseurs sonic cleaner did not cause my rings any harm! They look stunning right now and I'm looking forward to seeing them shine in my office tomorrow under the flourescent lights!!!! Now... A few questions... How long do you soak your rings in the solution? How hot is the water? How often do you soak them during a week? YOU are diamond cleaning IDOL!!! Thank you!!!!
