Tenax
Zero Purple Liquid Stain Remover
Best deep-cleaning solution for natural stone and ceramic surface maintenance.
The Tenax Zero Purple Liquid Stain Remover is a specialized cleaning treatment designed for porous surfaces like marble and granite. This powerful, water-based formula utilizes active chlorine to penetrate deep into the material, effectively eliminating existing stains while actively preventing the formation of new spots and shading. It is safe for use on polished natural stone surfaces because it is non-aggressive, and it also works on rough-finish ceramic stonewaves. Application involves spreading the product and allowing a contact time of 30 to 60 minutes before rinsing thoroughly. Always perform a preliminary test in an inconspicuous area before full application.
