Cleaning
Fill your wash-basin with tepid and put the stone into it (use with the lift-help), add some dish-washing powder.
It is sufficient to clean the stone with a dish-cloth; only in case of strong dirt or crusts use a scratch.
The INOX - serveboard and the glass bowls can be cleaned even in a dish-washer.
It is sufficient to wipe the wooden plate with a moist cloth.
