Even the most robust faucet surfaces need a minimum of maintenance. The more gently you treat your faucets, the longer you can enjoy the shine of the fine surface. A soft cloth is therefore the right tool for cleaning. You should never use caustic, scouring, or aggressive cleansing agents, they attack the surfaces and thus dull the finish. Different materials need different cleaning methods. The following explains how you can clean your faucets gently as well as thoroughly.
Chrome surfaces should be cleaned with a mild washing liquid or soap. In order to remove calcium, you should not use cleansing agents which contain mineral acids (e.g. hydrochloric acid) or aggressive organic acids (e.g. acetic acids).
