The Koch-Chemie Reactivation Shampoo is a great soap for descaling ceramic coatings. A strong foaming, acidic shampoo used to reactivate cearmic seals. Hydrophilic dirt such as dust, limescale and salts are removed by washing with the Reactivation Shampoo. Such dust impairs the easy-to-clean effect and the hydrophobic effect of the cermaic-sealed surfaces. The acidic setting of the shampoo ensures that the dirt is loosened and removed. This revives the dirt and water-repellent properties of the ceramic coating.
