This jewelry cleaner works much better than I anticipated. It is single use. All you have to do is fill the container with water followed by the addition of ten drops of solution, which come in a separate bottle, then shake it up a bit. What I like the most is that the solution is fresh every time so I am not re-dipping in dirty cleaner. Jewelry comes out dazzling! There is a brush supplied for those items that need a little extra cleaning or hard to reach areas. The solution bottle is a nice size so it can be used many times.
