•
Before cleaning, remove any dirt burnt onto the stone with the aid of
a metal spatula or a scraper of the kind used for cleaning ceramic
hobs;
•
For best results, the stone must still be warm; otherwise, wash it in
hot water;
•
Use metal mesh or non-abrasive scouring pads, dipped in lemon or
vinegar;
•
Never use detergents;
•
Never wash in the dishwasher;
•
Never leave the stone to soak;
•
The damp stone must not be used for a least 8 hours after the end of
the cleaning procedures;
•
Over time, slight cracks may appear on the surface of the stone. This
is due to the normal expansion of the stone's finishing glazes at high
temperatures.
