Marble is a metamorphic rock resulting from the transformation of limestone or dolomites. Marble requires attention and need to be installed mainly indoors. Being a so-called limestone, it remains a porous material, its absorption rate varying according to the marbles.

Daily, use dishwashing liquid, black soap or diluted linseed oil soap mixed with lukewarm water. Rub stained and/or dirty areas with a soft brush or sponge. Rinse thoroughly and remove excess water.


Granite is a very solid and resistant magmatic stone. The granite has a low porosity and is very resistant to bad weather. Suitable for making work plans for kitchens, it resists heat and is easily maintained.

Daily, degrease granite with a sponge and dishwashing liquid. If a stain persists, rub with a soft brush and dishwashing liquid then rinse with warm water. If a spot is too encrusted, consult the Ateliers Sansone.


Blue stone is an authentic natural stone, which is sensitive to bad weather and aggression. Therefore, it is used both indoors and outdoors.

Daily, clear water is sufficient to clean the blue stone. It is possible to add a small amount of neutral PH soap to the water. Daily cleaning with soap nourishes the stone and allows it to be protected against some attack.


Quartz is a material adapted to kitchen worktops, easy to maintain. Non-porous, it does not absorb liquid which facilitates cleaning.

Daily, degrease quartz with a sponge and dishwashing liquid, mixed with warm water. Rinse the surface thoroughly and remove any excess water. If a spot is too encrusted, do not hesitate to consult our team.

Important advice

Marble, stone and quartz are sensitive to acidic products (vinegar, lemon, etc.) & detergent products. Quartz also fears UV rays and its resistance to heat is limited. In case of doubt, do not hesitate to consult the Ateliers Sansone.
