I have used the tabs to clean my toilet sink (6-8 tabs), my porcelain washbasin (5-6 tabs), and for descaling of my coffee (1-2 tabs) and my kettle (1-2 tabs). Works beautifully. The tabs dissolve in boiling water under any circumstances. There remains no unpleasant taste in the coffee or the kettle back, rinse again afterwards is quite sufficient. The tabs are also suitable for cleaning of fittings, but you have to dry the Tabs pound (unfortunately, very hard, a mortar is recommended) and the sponge diving earlier in warm water. Use the tabs, are inexpensive and save so many cleaners.
