Each sink has two nuts, which are embedded in the bottom. This allows the washbasin to be securely mounted on any washbasin.
If the washbasin is mounted on a wooden table care must be taken to ensure that the pickling, painting or treatment agents that may be used are completely dry. If mortar, plastering or painting work has to be done in the bathroom or toilet after the sink has been installed, the basin must be carefully covered. Highly concentrated acids and bases can cause chemical reactions with the copper, causing color changes and destruction of the patina.
Therefore, no acidic or basic silicone may be used for the assembly. Do not use silicone with any of the following ingredients: acetate, acetic acid, acid, aceto, amino. The copper sinks should only come in contact with neutral crosslinking silicone, which is available in every hardware store. As a test, you can smell the tube shortly after opening it: if the silicone smells unpleasant don’t use it for our copper sink.
Because of the manufacturing process of our washbasins a patina of copper oxides is created and protects the pure copper underneath from further reactions. Therefore, the look of our sinks is maintained over many years.
Chemical agents used in everyday life in the bathroom are not a problem. For more aggressive agents such as hair coloring, bleach, nail polish remover, and the like, make shure that they are acid free. It is also recommended after use of such products to rinse the basin briefly with water.
Above all, acetic acid-containing substances must not come into contact with the sink, otherwise the toxic copper acetate (verdigris) can form. If limescale builds up in the sink, try to remove it carefully mechanically. Only use chemical lime removers if they are acid-free. Most of these special limescale cleaner are offered for use on natural stone. These cleaners can also be used on our copper sinks. Residues of any chemical cleaning agent should be washed immediately after cleaning the basin.
The washbasin does not have overflow protection, so if there are children in the household you may want to consider a non-closable drain system.
For the care of the copper, it is recommended to rub an odorless oil or fat into the basin 3-4 times a year and then dry it with paper. You can use furniture oil for example. When cleaning the washbasin, do not use a scouring pad or the rough side of a cleaning sponge, otherwise the patina of the copper will be damaged.
