Use a soft cloth for all operations and never abrasive wipes.
Never use powder detergents, alcohol or acetone, as these will irreversibly damage the material; use only liquid detergents free of alcohol and ammonia.
To remove any lime deposits on the surface, wipe with a soft cloth soaked in lemon or vinegar, preferably heated.
To avoid limescale stains on taps, simply wipe them dry after use.
