This stuff's expensive! Dawn dish liquid, + (3) about 1 cup of water, + (4) a good empty jar -- [I use the empty jar from the first jewelry cleaner I bought about 20+ years ago.] I just add my rings to the jar and GENTLY “shake” it. I also let it sit for as long as I want when I’m busy (They’ve even been in there overnight before). All I have to do when I remove the jewelry, is rinse well. It’s AMAZING how the diamonds sparkle!!!
