Stone protection instructions
Natural stone can be partially subdivided into hard 
and soft rocks. In the group of hard rocks belong granite, gneiss, quartzite and porphyry, while in the group of soft rocks – all types of marble, limestone, travertine and marble onyx.
Marble is a subtype of limestone, which is exposed to acidic substances; as a result the surface of the stone is affected. On the unpolished (faceted) stone it’s less obvious; while on the polished surface mat spots appear in a second and are almost impossible to clean. In this case the surface of the stone is to be repolished (if it’s possible in a given case). That’s why it’s advised to avoid acid containing liquid (vine, fruit juice, Coca-Cola, vinegar, lemon juice), as well as acid containing cleaning substance contact with marble surfaces.
It is not advised to use abrasive cleaning substances and hard brushes on marble surfaces, because they also can leave scratches and wales. Every surface of stone in bathroom is exposed to water; therefore they must be regularly treated with water and grease repelling substances.
The majority of kitchen top surfaces made of marble or granite needs to be treated with stone cleaners, which delay oil, grease and water permeation into work surfaces. If light stone surface gets in contact with deep coloring products (beets, cherry juice), it must be immediately cleaned with damp napkin.
Appropriate and regular stone care is the main condition so as natural stone ware look good and serve long. Even small scratches and mat surface will be less visible, if stone will be treated correctly and regularly, by using only for natural stone tailored cleaning and care substances. We recommend using “Lithofin” or “AKEMI” production.
