Deep cleaning of marble and granite without removing the natural sheen or damaging the surface has always been a problem. LEM-3 is the solution! Diluted in water in suggested ratio. LEM-3 acts vigorously against dirt and delicately with the material to be cleaned. Pleasantly perfumed and with the pH factor specifically studied for a deep cleaning of marble or any other stone material without damage, this is surely the detergent for the professional.
