The gel is dedicated to sanitization and extensive cleaning of the fixture and sanitary devices, including toilet bowls, urinal, bidets, etc. Silver nanoparticles get rid of bacteria, viruses and fungi, leaving the toilet crystal clear. Owing to an increased viscosity, the gel adheres to the cleaned surface for a longer time. It is ultimately efficient against water scaling, rusty weeping, soap-based and lime soils. It removes the residues of the cement mortars. When used regularly, it polishes and protects against repetitive soiling.
