Very good at normal tarnished silver and stains. Very pleasant to use. If you take time, you can also remove heavy redactions with Butler's hand alone policy. For me, the two-stage cleaning silver has proven itself for cutlery. Any more tarnished parts come first in a soda-salt-aluminum bath. It sounds complicated, but is simple: plastic bowl with aluminum foil, reinlegen silver parts, each pour one to two tablespoons of baking soda and salt to and with hot water. Top front of an open window in a just unused space, because the chemical reaction produced hydrogen sulfide. This gas does not smell good and is not healthy. After about twenty minutes, barely forming gas, instead an easily removable light coating on the cutlery. Now tilt away the water, the cutlery Rinse and dry. The immersion bath has then a lot of the redactions removed on the silver, but not everything. Therefore, polish with Butler hand. Then the silver looks almost like new. Silver parts Zierschwärzugen not the soda-salt-aluminum bath, the ornaments are then possibly off also. The technique only try with insignificant items and see whether the desired result is achieved. And so please little as possible to the hydrogen sulfide "sniffing".
