Sinks made of stainless steel

The sink should always be wiped dry with a soft cloth after every use so limescale isn't even given a chance to settle on the surface.
"Blancopolish" is recommended for intensive cleaning and to refresh the surface. It removes minor signs of wear with ease, and helps to prevent fingerprints and new dirt. Water simply rolls off. And it leaves the sink looking wonderfully shiny.
Please note: many of the materials that are used in the kitchen are harder than stainless steel (e.g. porcelain, ceramic knives etc.). It is in the nature of these materials to leave signs of use.
Sinks made of SILGRANIT

SILGRANIT, the granite-based composite material developed by BLANCO, contains water- and dirt-repellent substances that are brought up to the surface every time the sink is cleaned.
This provides permanent protection against limescale and stains for maximum ease of care.
Usually a damp cloth is all that is required for your sink to stay clean and lovely.
More stubborn marks can be removed in moments with a damp sponge.
However, any limescale or dirt deposits that do form can easily be removed using BLANCOACTIV, any standard commercial washing detergent, acetic acid or household cleaning product with active oxygen.
