This worked great on some old sterling silver jewelry of mine that had not been cleaned in years. Curiously, I had trouble cleaning a silver necklace that I had bought recently. Not sure why. But, I will be keeping these as they work great on most silver. Yes, they do have an odor, but that is to be expected with this type of chemical remover. It doesn't bother me and washes right off. From reading these reviews, I have decided to clean some silver serving bowls with it. How convenient.
