Koch Chemie RS Reactivation Shampoo is descaling soap for ceramic coatings. Strong foaming, acidic shampoo to reactivate ceramic seals. Hydrophilic dirt such as dust, limescale and salts are removed by washing with the Reactivation Shampoo. Such dirt impairs the easy-to-clean effect and the hydrophobic effect of the ceramic-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.
