Cleaning of the soapstone
: the soapstone is a natural stone, therefore minor colour
differences may occur; as it is normal, they may not serve as a basis for quality com-
plaints! To clean the soapstone from dirt and fat with water and soap, as well as small
scratches, use sand paper (grain size 240).
Warning
:
Under no circumstances you may use sponge, scouring, aggressive
or scratching cleaning agents!
If the grate is blocked so that the equipment cannot
serve the intended function, the grate is to be removed for cleaning.
