Sandblasting glass beads/Abrasive glass beads
Glass beads abrasive with their hardness and spherical form can remove impurities and metal oxides without damaging the treated surface. Glass does not react chemically with other material so that the micro-beads do not create any corrosion on the treated surfaces with no deposits of foreign substances.
