Description
Deep-penetrating stain remover for absorbent natural stone. Tenax Zero Purple is a water-based active chlorine solution engineered for removing existing stains from absorbent natural stone surfaces — marble, granite, and select rough-finish ceramic — while helping prevent new spots and shading from forming. Non-aggressive on polished natural stone finishes when used as directed. Apply by roller or brush, allow to dwell 30–60 minutes, then rinse thoroughly.
Coverage: approximately 160–270 sq. ft. per liter. Store below 77°F.
⚠️ Important: Contains active chlorine. Avoid contact with metals and certain plastics. Not recommended for onyx or other alkali-sensitive materials. Always test on a small hidden area first.
