Due to its proper formulation, CRYSTAL GREEN glass cleaner is recommended for cleaning glass and all types of enameled or vitrified surfaces. Spray only once at 20 cm from the surface. Then dry with paper or a cloth that leaves no residue. It is not necessary to clarify. A dosage and a suitable temperature allow to minimize the consumption of water and energy as well as to reduce the contamination of the water. This product is not designed for large-scale cleaning. In case of persistent dirt, repeat the cleaning process.
