The impurities stains on the surface of the sink are usually lime residues which, depending on the degree of hardness of the drinking water in your region, may be of greater or lesser intensity. These wastes capture dirt particles in a palpable way, so in a short time these unsightly stains are produced. Likewise, the small particles of iron and oxide of the pipes, especially in new constructions or when they are made repairs of the same, give the impression of generating marks of oxidation.

To avoid these stains, we recommend wiping the sink surface with a cloth after each use.
