I prefer their mitts to the polishing cloths. You just slip a mitt on and rub the item in your kitted hand. I never use the cream. I use the method below.
I mix ammonia with water in a small bowl and let a silver piece sit in it for awhile. NOTHING with stones goes in....just silver. When I rinse it off, its prefect. I learned this from a friend who owns a dental lab. He used to clean pieces for me in a sonic machine in the lab and told me how to do this at home. I mix the ammonia to water at a ratio of about 1 part ammonia to 2 parts water. I put in one piece and make sure that all of it is getting exposed to the mixture while it sits for about 20 minutes. Then I just rinse it off under running water and dry. It's comes out like new. I have a large collection of Elsa Peretti silver pieces, so I do this often.....but remember, only metal....no stones.
