Removing limescale gently
If limescale has formed, it is best to treat this with a mild, organic acid, e.g. a solution of acetic or citric acid. Important: before applying the substance, check whether your surfaces are resistant to acids. Marble and aluminium, for instance, should not be cleaned with acidic substances. Many plastics and varnishes are also sensitive to acid. As the owner of a BLANCO mixer tap in Stainless steel, Silgranit look or Ceramic look, however, you’re good to go: if used correctly, these materials tolerate cleaning with acetic or citric acid without any issues. Instead of acid cleaners, you could use a mild descaling spray, such as BLANCO Antikalk. This limescale-removing agent has been specially developed for BLANCO mixer taps and sinks. It cleans gently yet thoroughly.
To remove limescale, apply the cleaning agent to the soft side of a sponge and wipe the mixer tap thoroughly. Be sure not to leave acid-based cleaner on for longer than indicated on the package instructions. Avoid lengthy, vigorous scrubbing with the rough side of your sponge. This can scratch your mixer tap. Rinse your mixer tap down with clean water and rub it dry with a microfibre cloth.
