Natural stones usually require very little maintenance, but still they need attention when you clean them. Use only the appropriate preparations for this purpose. It is better surfaces to be impregnated due to prevent wear out or discoloration. For routine cleaning, use a cellulose sponge, not natural, because it can be easily destroyed when you rub it on the stone surface. For floor cleaning is recommended sponge - mop instead of others, made of strips, because they often leave drops .
