I use this jewelry cleaner I got at the county fair:

I love it! It smells like bananas...
The jewelry cleaner you get at the jewelers is just ammonia, that's why it smells awful. You can do it cheaply yourself. Buy ammonia at
walmart or something, soak your ring in it, and use an old toothbrush to get off the grime.
I personally like my banana-smelling cleaner...
